At Manatawny Creek Winery, we focus on sustainable vineyard practices that improve soil health and reduce environmental impact. We’ve ditched chemical fertilizers entirely in favor of compost made from horse manure sourced at local farms, along with grape skins, seeds, and stems left over from our own production — compost! Composting does more than just feed the vines; it builds healthier soil by boosting organic matter and encouraging the beneficial microorganisms that a thriving vineyard depends on.
Growing grapes on the East Coast comes with its own set of challenges. Our humid climate creates the perfect conditions for fungal disease, which has historically meant heavy pesticide use. We’re actively changing that. Natural phosphorous acid products now replace harsher compounds in our fight against downy mildew, and instead of conventional insecticides, we use pheromone ties and an insect growth regulator to disrupt grape berry moth mating cycles. We’ve also refined our canopy management by opening up the fruiting zone to improve airflow, which naturally reduces our need for sprays.
Weed management is another area where we’re pushing ourselves to do better. We’ve phased out pre-emergent herbicides, which can linger in the soil and surrounding ecosystem for years, and shifted to post-emergent options that break down quickly. At the same time, we’re experimenting with methods that could allow us to reduce or even eliminate herbicides altogether.
Sustainability is a process, not a finish line. We’re continually learning, adjusting, and improving, with the goal of producing exceptional wines while caring for the land that makes them possible.
Sustainability isn’t just a vineyard concern — it extends to every corner of how we run our business. One of our most significant investments in reducing our environmental footprint has been the installation of an 11-kilowatt solar energy system, which you can’t miss if you visit: an entire roof blanketed in photovoltaic panels. Here’s how it works — when sunlight hits the silicon cells in each panel, it stimulates electrons to flow in a circuit, generating direct current (DC) electricity. That electricity travels to three inverters on our crush pad, where it’s converted to alternating current (AC) and fed into our electrical panel to power the winery. Any surplus energy we don’t use gets pushed back out to the grid for others to draw from.
Waste reduction is another area where we’re always looking to close the loop. During harvest, we generate significant amounts of pomace — the grape skins and seeds left behind after pressing — along with stems removed during destemming. Rather than discarding any of it, everything goes straight to our composting area, where it’s combined with horse manure from neighboring farms and transformed into the rich compost we use to nourish our vines. We’re also experimenting with composting our used filter press pads, with the goal of keeping them out of the landfill entirely.
Even in the office and tasting room, the small choices add up. We recycle toner cartridges, use recycled paper for our tasting notes and wine labels, and find second lives for used wine bottles — either through recycling or by passing them along to customers who make their own wine at home. We’re also keeping an eye on emerging alternatives, like recyclable aluminum capsules that could eventually replace the tin capsules we currently use.
There’s an old Iroquois principle, part of their “great law of peace,” that captures this mindset perfectly: every decision should be made with the next seven generations in mind. That idea sits at the heart of everything we do at Manatawny Creek Winery, whether we’re tending the vineyard or finding smarter ways to run our business.
Tannins are compounds in wine that dry out your mouth; in fact, many people get the terms “dry” and “tannic” confused for that reason. Dry simply means a lack of sweetness. Tannic means a noticeable level of tannins. They are detectable because they bind with the proteins in your mouth leaving a dry, puckering sensation. These compounds are present in the skins and seeds of grapes. Red wines have more tannins than whites since red grapes are fermented in contact with the skins and seeds. Winemakers who want to get more tannins in their red wines, will leave the wine on the skins and seeds for a long period of time during fermentation. Winemakers who want less tannins may use fining agents to remove tannins from a wine. Tannins are also present in oak, so wines that are aged in oak barrels tend to be more tannic due to the tannins extracted from the barrel.
Tannins are a part of a group of compounds called Phenolics and have antioxidant properties which have been in the news lately because of the health benefits. The amount of tannins that people like in a wine is a very subjective thing. Some people like more than others. The type of food you are eating with a wine may also determine your enjoyment level regarding tannins. At Manatawny Creek Winery, we tend to make our wines with relatively low levels of tannins.
Malolactic (often shortened to ML) fermentation, sometimes called the secondary fermentation, typically follows the primary fermentation (where the yeast convert sugar to alcohol). In this ML fermentation, bacteria convert malic acid in the wine to lactic acid, thereby reducing acidity and making the wine softer. Sometimes these bacteria produce a buttery or butterscotch character during the fermentation. ML bacteria are added to certain wines depending on the desired style. At Manatawny Creek Winery, we put all of the dry reds through ML including the Cabernet Sauvignon, Merlot, Cabernet Franc, Pinot Noir, Meritage and Chambourcin. The only white that typically gets put through ML is the Chardonnay; the butterscotch character that may be noticeable in the Chardonnay is due to the ML fermentation. The Pinot Grigio may or may not get put through ML depending on the acidity. Fruity wines like the Riesling or Vidal Blanc will not get ML bacteria added, because we do not want anything to take away from the fruit.
Sulfites are a class of compounds added to wine and other foods as a preservative. They are natural compounds that have been used as an anti-oxidant and anti-microbial agent in wines since early recorded history. Concern arose over sulfites when people got sick by eating food at salad bars that was treated with very high levels of sulfites. There are some misconceptions about sulfites that we’ll try to clear up:
All wines contain sulfites: red, white, French, American, Australian, etc. Yeast naturally produce sulfites during fermentation. Nearly all winemakers add sulfites, including those from all over the world. The U.S. Government requires wine sold in the U.S. to label wine if it contains sulfites. If you drink foreign wine while abroad, you are not being warned, but the wine still contains sulfites. Organic wine must be made without added sulfites, but these wines are quite perishable. The level of sulfites in wine is very small, especially when compared to other foods. Typical levels in wines are about 80 100 ppm (parts per million). Dried fruit, such as apples and apricots are typically packaged with 500 2000 ppm sulfites.
Research has shown that sulfites do not cause headaches. There is something in red wine linked to headaches, but the cause has not yet been found. We recommend drinking extra water when you drink wine, simply to avoid dehydration which can cause headaches.
The answer is that we never add any flavorings to our wine – all the flavors that are described occur naturally from either the grapes themselves, the yeast during fermentation, or oak barrels during aging. For example, even though most of our wines are made from grapes, other fruits like strawberry, cherry, raspberry, and blackberry emerge from the grape during fermentation. These fruit flavors and aromas are very subtle most of the time, but often you can detect them when you are looking for them. Other aromas and flavors, like butterscotch for example, are caused by malolactic bacteria during a secondary fermentation (see website for last month’s question of the month).
Wines that are aged in oak, like the Cabernet Franc and Merlot, exhibit aromas of vanilla and toasty wood, which are extracted from the barrel into the wine during the aging process. Certain types of grapes make wines with distinct characteristics. As an example, Gewurztraminer, a white grape, will often make a wine that has aromas of rose petals and lychee nuts. Pinot Noir, a red grape, may contain aromas of strawberries, mushrooms and violets. So next time you’ve got a glass of wine in front of you, open your mind to all of the many possible flavors and aromas, and see if that changes your wine-drinking experience!
White oak is the favorite wood used in barrels and imparts both flavors and tannins to wine. Typical oak flavors include vanilla, toast and smoke. The barrels lose their ability to impart flavors after 3 to 5 years of use and the oak character diminishes each year. Wineries who use new oak every year need to charge more for the wine because barrels are so expensive; a typical American barrel costs about $350 while French barrels can cost over $700. Many winemakers think that American oak has a stronger, sweeter character than its French counterpart. The other major region of the world that supplies oak for barrels is Hungary and Hungarian oak barrels seem to have a more smoky character than others.
Most of the oak in America comes from Kentucky, Missouri, Tennessee and Ohio, but it turns out that the Appalachian mountains in Pennsylvania are a great source for slow-growing oak and companies are starting to make PA barrels. Most of the barrels we use at Manatawny Creek Winery are Pennsylvania oak barrels for a truly PA product. French oak is used in our Pinot Noir and Hungarian oak is used in our Merlot, but PA oak dominates the Cabernet Franc, Cabernet Sauvignon, Chardonnay and Meritage!
It is our Ganimede tank and is a special tank used to ferment red wines. There is a cone inside that collects the carbon dioxide generated during fermentation; every few hours, a valve is opened that releases the carbon dioxide and disturbs the cap that is formed. In this manner, the skins that rise to the surface to form the cap now come in contact with the wine, imparting color and tannins. We can only use this tank when we have at least 3 tons of 1 variety of grapes. Otherwise, we need to ferment in the macrobins and punch the cap down by hand which is backbreaking work sometimes.
If you happen to be sitting on the deck during harvest, you may feel like you’re in the middle of an earthquake when the valves on this tank open – it gets rather violent!
The answer is pretty simple; our vineyards are not located in Champagne, France. So why the confusion? Because some of the large bulk wine producers in California and New York started calling their cheap sparkling wine Champagne . This, of course, infuriated the French. True Champagne comes only from France ‘s northernmost winegrowing area, the Champagne region. Manatawny Creek Winery, along with most American sparkling wine producers, elects to use the term sparkling wine in order to show respect to this great wine-producing area. True Champagne also requires the use of methode champenoise which is the traditional method of producing bubbles in the wine by conducting a secondary fermentation in the bottle. Both of our bubblies are produced using methode champenoise, a very labor-intensive production method. But one that produces very tasty results! And remember, Champagne and Sparkling wines are not just for New Years’ celebrations ? they should be enjoyed throughout the year!
We tell you that our Blanc de Blancs is made in the traditional Methode Champenoise style but what does that really mean? And how on earth do you pronounce it? According to my favorite book, Wine Lover’s Companion, it is pronounced may-TOD shahm-peh-NWAHZ. It is a process where the bubbles are produced by a secondary fermentation that actually takes place in the bottle.
We put a base wine with some added sugar and yeast into bottles closed with crown caps. The yeast ferment the sugar producing carbon dioxide that has nowhere to escape to, causing bubbles to form. After about a year in “tirage”, these bottles are put in riddling racks, where they are subjected to turning every day until all of the sediment from the fermentation has fallen into the neck of the bottle. Then, one cold day in the winter, we disgorge to remove the sediment; this is done by freezing the necks of the bottles so the sediment is trapped in an ice plug. The bottles are turned over, the crown caps removed, and the ice plug shoots out of the bottle. We than add a dosage of wine and sugar and cork the bottle. A wirehood is placed over the cork so the cork is not pushed out of the bottle by all the pressure. It’s a heck of a lot of work, but well worth it!
Port is a sweet, fortified wine that is typically served after a meal. The process to make port differs from the typical winemaking process for table wines in that the fermentation is stopped about halfway by the addition of grape neutral spirits. This results in a wine with an alcohol content between 18% and 20% with a lot of the natural sweetness from the grape remaining. Port originated in Portugal’s Douro Valley and the name comes from the fact that historically, these wines were shipped out of the city of Oporto.
There are three basic categories of port made with red grapes – vintage, ruby and tawny (white port is made with white grapes but is much less common). Vintage ports, the expensive type, are made from grapes of a single vintage and are typically bottled with only a little more than a year of aging in barrel. They are only made in declared years in Portugal and the consumer is expected to do most of the aging since Vintage port gets better with age and often needs many years to become drinkable. Ruby port can be made from grapes of different vintages and is aged for about 2 years before release. It is typically ready to drink when released and is simpler and less expensive than Vintage port. Tawny ports are made from grapes of different vintages and aged in barrels to purposely undergo slow oxidation; this turns the color of the red wine to a tawny color and gives it a unique character. The label of a Tawny port will often show the average number of years of aging – typically 10, 20, 30 or over 40 years.
The grape varieties used in port in Portugal are numerous and varied and do not include anything that we grow in Pennsylvania. At Manatawny Creek, we make our port from Cabernet Franc, one of the red varieties that grows very well in our area. We produce it in the vintage port style, using grapes from a single vintage and bottling the wine after 1 year of aging in neutral oak. Our port definitely benefits from several years of aging and, just like true Portuguese Port, is the ideal beverage to pair with chocolate!
We hear this question all the time and the answer is quite complicated. But basically, it really depends on the type of wine, how it’s made and personal preference. Let’s discuss each of these 3 factors one at a time.
The type of wine is very important when considering how long to hold a wine before drinking it. As a wine ages, it tends to lose fruit and gain complexity. Typically, fruit wines and most white wines should be consumed young before they lose a lot of fruit character. Oak-aged white wines like Chardonnay can sometimes be held longer because they have acquired some tannins from the barrels that give them some aging capacity. Red wines can typically be aged longer than white wines, although there are exceptions. Certain specialty wines, like Vintage Port, can be aged for a very long time. The grape variety and the location of the vineyard plays a critical role when determining aging capacity; a big Cabernet Sauvignon made from grapes grown in Bordeaux will last much longer than a fruity Concord made from grapes grown in Pennsylvania.
Winemaking practices have an effect on aging capacity of wine. Factors that affect the aging potential such as levels of acid, alcohol, sugar and tannins can be manipulated by winemakers. Taking tannins that we discussed in last months’ Question of the Month as an example, a winemaker may leave the wine in contact with the skins during fermentation for a few weeks to make a highly tannic red wine. Alternately, there are fining agents that can be used to remove tannins to make a less tannic wine. A highly tannic wine will taste much better after years of aging because upon aging, tannins bind together and create a softer, more drinkable wine.
Possibly, the most important factor when deciding on how long to age a wine is personal preference. Some people prefer fruit-forward wines while other people will exchange fruit for complexity. Some people like tannins while others don’t like that puckering sensation that tannins can cause. The list goes on. Preferences can also be affected by what you are eating with the wine, but that is another topic!
So what do we recommend for our wines? All of our fruit wines and white wines will be best if consumed within 1 year. The exception would be our oak-aged Chardonnay which some may prefer with another year of aging. The fruity red wines like the Harvest Red, Concord and Chambourcin also fall into the 1-year category. Our dry, oak-aged reds like the Merlot, Cabernet Franc, Cabernet Sauvignon and the Meritage are made to be consumed upon release, but will also do well with up to 2 or 3 years of aging. Our Port definitely needs a year or two of aging before reaching its peak and should be drunk within 5 years.
After a bottle of wine is opened, the wine is immediately exposed to oxygen which causes spoilage reactions to occur. If an opened bottle with headspace is left out on the counter in your kitchen, the wine’s flavor will start to change and the wine may spoil in a few days. Spoilage does not mean that the wine is harmful to drink; in this context it could mean anything from vinegar to just not “tasting good” anymore.
So how do you make an opened bottle of wine last longer? There are 2 major things you can do. The first is to chill it by putting it into the refrigerator; with red wine, you would just need to allow enough time to warm the wine up before serving again. The second is to remove the oxygen. The pump apparatus that people use helps a bit because it removes some of the air, but you can’t create enough of a vacuum to remove all of the oxygen. Spraying compressed gas (Private Reserve for example) into the bottle helps also because you are replacing oxygen with an inert gas like nitrogen or argon. But the absolute best way to remove the oxygen is to pour the remaining wine into another smaller container. Our suggestion is to get a 375-mL bottle (half-size bottle) and when you open a bottle that you will not finish, pour half of it into the smaller bottle. That leaves 2 glasses for now and 2 glasses for later!
Wine should be stored in a cool location where a constant temperature is maintained. Heat is a wine’s enemy so no matter how nice it looks, don’t install a wine rack in a cabinet above your stove or refrigerator! High temperatures make a wine age must faster than normal. Fluctuations in temperatures force air in and out of the bottle and can also cause rapid aging due to exposure to oxygen. Wine coolers are a great way to store wine, but are rather expensive. Usually, a nice, cool basement is a good location for wine storage.
One other thing to remember when storing wine with natural cork is that the cork must be kept wet. That means the wine either needs to be stored on its side or upside down. If the cork dries out, air can get into the bottle easier and cause spoilage. Wines with synthetic corks or screw caps can be stored in any position.
How do you pair wine and chocolate? Many people, in fact, think that wine and chocolate don’t go well together at all, but I think that great matches can be made between the right wine and the right chocolate. As with wine and food pairings, balance is the key; you don’t want the wine to overpower the chocolate and vice versa. With that in mind, the key ingredient in chocolate pairing success is sweetness level. I believe that oftentimes people try and pair sweet chocolate with dry wine that may not work very well. Sipping a dry red without any perceptible sweetness will taste sour and bitter after taking a bite of sweet chocolate.
The goal with chocolate pairing, therefore, is to try and match the sweetness level of the chocolate with the sweetness level in the wine. This can run the spectrum from a sweet Moscato with white chocolate all the way to 85% dark chocolate with Cabernet. We really like the way 60% dark chocolate complements our Cabernet Franc Port which is why we serve it to our customers in the tasting room. Of course subjectivity is also a factor, as is typically the case when talking about wine. Gather your friends with different kinds of wines and plates of chocolate and see what you like!
There are a few reasons why drinking wine could cause a headache and the answer really depends on the individual. The first cause is simply dehydration. Not keeping your body hydrated when drinking any alcohol can cause a headache. The second cause is tannins. Tannins, which are found in the skins of grapes and are the compound that causes your mouth to feel dry and puckery when you’re drinking red wine, have been shown to make the body release seratonins and high levels of seratonins can cause headaches. Tannins are present at much higher levels in red wine than in white wine, so if only red wine gives you headaches, tannins may be the cause. The third potential cause is histamines.
Histamines are also present in the skins of grapes and the fact that some people lack an enzyme to break down histamines efficiently has led researchers to believe that histamines can contribute to headaches. This theory, however, has been questioned based on other studies that have not supported it. Once again, only red wines would cause headaches if histamines were the culprit. The last potential cause of headaches is sulfites. This theory is questionable, however, because typically white wine contains more sulfites than red wine and red wine is usually to blame for headaches. Also, a more typical response to sulfites is respiratory problems rather than headaches.
So what should you do if you get headaches? I personally make sure that I drink one glass of water for each glass of wine consumed. If you think tannins may be the cause, try and choose red wines that are lower in tannin content; for example, drink Chambourcin instead of Cabernet Sauvignon. The histamine hypothesis people believe that taking an anti-histamine before drinking wine could help. Obviously, asking the advice of your doctor would be a good idea. Another good idea would be to keep a log of which wines that you drink cause the headaches and see if any kind of pattern emerges – hopefully your favorite wines are not the culprits!
Late harvest is a wine term that simply means a wine made from grapes picked toward the end of harvest. The grapes are typically allowed to hang longer than usual so the sugars accumulate, the flavors intensify, and the grapes get very ripe. Late harvest wines are sometimes confused with ice wines which are made from grapes that are allowed to hang even longer until they actually freeze on the vine.
The most popular varieties used to make late harvest wines are Riesling, Gewurztraminer, Muscat, Semillon and Sauvignon Blanc. The final two are used to make probably the most famous dessert wine, Sauternes, in France’s Bordeaux region.
Our late harvest Muscat is made with four different Muscat varieties: Muscat blanc, Muscat Ottonel, Muscat of Alexandria, and Orange Muscat. We grow the Muscat Ottonel in our own vineyard and the other three are from Pagoda Hill Vineyard in Oley. We are loving this wine – hope you do too!
We have competition from lots of different wildlife for our wonderful grapes growing in the vineyard, but the species that does the most damage is deer. In the spring, the adorable creatures come into the vineyard and chomp on the young tender shoots; if they eat too much, they can actually kill a vine. More damaging, however, is in the fall when they come in and eat the ripening grapes. It’s absolutely amazing how many grapes a herd of deer can eat in one night. In 2009, we lost at least 10 tons of grapes to deer. Yes, that is 20,000 lbs of grapes!!! Not wanting a repeat of 2009, we had 8-foot deer fences installed in both vineyards in 2010. Now we watch and laugh as the deer stand outside the fence, longingly wishing for the good old days. It’s very satisfying.
The creatures that run a close second to deer are the birds. We have the adorable backyard birds like robins, doves, bluebirds and goldfinches that peck a few grapes here and there. The real culprits, however, are the huge flocks of starlings that swoop down en mass from the trees and peck many grapes at once. To avoid bird destruction, we put bird netting over every single row of grapes in the vineyard. That is the easy job. Once the grapes are harvested, we have to pull off the netting and stuff it back into the bag for next year which is the harder job. If we didn’t net our vineyards, the birds would eat all of our grapes! Of course sometimes “smart” puppies get stuck after playing in the nets and need a little assistance.
The government requires a winery to put the geographic origin of the grapes used to make the wine on the label. This is the appellation and it can either be defined by political boundaries, such as the name of a county or a state, or by American Viticultural Areas (AVAs), which are federally-recognized growing regions. Famous AVAs include Napa Valley or Sonoma Valley. Obviously, we use the appellation Pennsylvania on our wine labels, but does that mean that all of the grapes have to be grown in Pennsylvania? Sadly, the answer is No. The government allows up to 25% of the grapes to be grown from outside the state. That means that even though a bottle of wine has the Pennsylvania appellation on the label, it could possibly contain a significant amount of grapes grown in California! Crazy, huh. So how do you know if you are actually getting a locally-grown product? You have to ask the producer.
We at Manatawny are committed to using local fruit. We grow about half of the grapes that we need and the rest are purchased only from vineyards in Pennsylvania, with the majority from local vineyards. The exception is Niagara and Concord grapes which we buy from the Erie, PA area.
