Nothing feels as satisfying and authentic as
making your first batch of wine from fresh grapes. And there's no
better time to try it than in early autumn, when grapes all over the
country are ripening in vineyards and backyard gardens.
There are many kinds of grapes to choose from,
depending on where you live. Vitis vinifera is the classic choice for
flavor, varietal character and historic authenticity. This famous
European wine-grape family includes such renowned varieties as
Chardonnay, Merlot, Zinfandel and Cabernet Sauvignon. In the United
States, to make a sweeping generalization, v. vinifera grapes thrive
in California and the Pacific Northwest. They also grow well in
microclimates scattered from New York to the Great Lakes, the
Mid-Atlantic states and beyond.
Those who live in colder, wetter climates may not
be able to find v. vinifera grapes grown locally. Don't be
discouraged. Fine hybrids and Vitis labrusca grapes, which are less
susceptible to cold and disease, may be growing near your home. Other
options include ordering grapes through your favorite local
winemaking shop or from a produce wholesaler.
Whatever kind of grapes you use, the general
techniques, equipment and ingredients are the same. Here's an
overview of some key steps along the way.
Basic Winemaking Equipment
Here's everything you need to make your first
one-gallon batch of wine from fresh grapes. You should be able to
find this equipment at any homebrewing or home winemaking supply
shop.
Large nylon
straining bag
Food-grade pail
with lid (2 to 4 gallons)
Cheesecloth
Hydrometer
Thermometer
Acid titration kit
Clear, flexible
half-inch diameter plastic tubing
Two one-gallon
glass jugs
Fermentation lock
and bung
Five 750-ml wine
bottles
Corks
Hand corker
Inspecting the Fruit
Winemaking starts with inspecting the grapes. Make
sure they are ripe by squishing up a good double handful, straining
the juice and measuring the sugar level with a hydrometer, a handy
device you can buy at a winemaking supply shop. The sugar density
should be around 22° Brix - this equals 1.0982 specific gravity or
11 percent potential alcohol - and the fruit should taste sweet, ripe
and slightly tart.
The grapes also must be clean, sound and
relatively free of insects and other vineyard debris. Discard any
grapes that look rotten or otherwise suspicious. Also, it's very
important that all the stems are removed, since they will make your
wine bitter.
Keeping it Clean
Winemaking demands a sanitary environment. Wash
all of your equipment thoroughly with hot water, boiling what you
can. It's also wise to arm yourself with a strong sulfite solution to
rinse any equipment that comes in contact with your wine. To make it,
add 3 tablespoons of sulfite powder (potassium metabisulfite) to a
gallon of water and mix well.
Adjusting the Juice
Adjusting the juice or "must" of your
wine is critical. Luckily, it's also easy. Acid content is measured
with a simple titration kit; you can buy one at a supply shop. The
ideal acid level is 6 to 7 grams per liter for dry reds and 6.5 to
7.5 grams per liter for dry whites.
Here's an example: If your must measures 5.5 grams
per liter, then you need to add 1 gram per liter of tartaric acid to
bring it up to 6.5 g/L. Since 0.2642 gallons equals 1 liter, 1 g/L is
equivalent to adding 3.8 grams of tartaric acid to your one-gallon
batch. Add this powder in one-eighth teaspoon intervals, checking
acidity carefully after each addition, until the desired level is
reached. You can buy tartaric acid at your supply shop.
You also need to monitor the sugar level with your
hydrometer. The must should be about 22° Brix for both reds and
whites. To bring the sugar concentration up, make a sugar syrup by
dissolving one cup sugar into one-third cup of water. Bring it to a
boil in a saucepan and immediately remove from heat. Cool before
adding in small amounts, one tablespoon at a time, until the desired
degrees Brix and specific gravity is reached. To lower the sugar
level, simply dilute your must or juice with water.
The temperature of your must can also be adjusted
to provide the perfect environment for yeast cells. Warming up the
juice gently (don't cook or boil it!) is an easy way to bring it to
pitching temperature without damaging the quality of the wine.
Fermentation can sometimes reach into the 80° to 90° F range,
though the 70° F range is standard for reds (whites often are
fermented at cooler temperatures).
If your grapes have been refrigerated or are too
cold, use this unorthodox but quick trick: Heat up a small portion of
the juice in the microwave, mix it back into the fermentation pail
and re-test the temperature. An electric blanket wrapped around the
fermentation pail also works, but takes longer. For cooling, add a
re-usable ice pack and stir for a few minutes. Pitch the yeast when
the temperature reaches 70° to 75° F for reds and 55° to 65° for
whites.
Racking
the Wine
"Racking" means transferring the
fermenting wine away from sediment. You insert a clear, half-inch
diameter plastic hose into the fermenter and siphon the clear wine
into another sanitized jug. Then top it off and fit it with a
sanitized bung and fermentation lock. This can be a delicate
operation and it's important to go slowly. You don't want to stir up
the sediment, but you don't want to lose your siphon suction.
Bottling the Batch
Bottling
may sound complicated, but it's really not. To bottle your wine, you
simply siphon your finished product into the bottles (leaving about 2
inches of headspace below the rim), insert a cork into the hand
corker, position the bottle under the corker and pull the lever. It's
always wise to buy some extra corks and practice with an empty bottle
before you do it for real.
Wine bottles can be purchased at home winemaking
stores, or you can simply wash and recycle your own bottles. These
supply stores also rent hand-corkers and sell corks. You should only
buy corks that are tightly sealed in plastic bags because exposure to
dust and microbes can spoil your wine. Corks can be sterilized just
before bottling, with hot water and a teaspoon of sulfite crystals.
A one-gallon batch will yield about five
standard-size (750 ml) bottles of wine. If the fifth bottle isn't
quite full, then either drink that bottle or use smaller bottles to
keep the wine. The key is to have full, sealed containers that are
capable of aging.
Now you're ready to make your first batch of
fresh-grape wine. Below you'll find step-by-step recipes for a dry
red and a dry white table wine. The recipes have similar steps and
techniques, with one important difference. Red wines always are
fermented with the skins and pulp in the plastic pail; the solids are
pressed after fermentation is complete. White wines are always
pressed before fermentation, so only the grape juice winds up in the
fermenting pail.
Dry Red Table Wine
Ingredients
18 lbs. ripe red
grapes
1 campden tablet
(or 0.33g of potassium metabisulfite powder)
Tartaric acid, if
necessary
Table sugar, if
necessary
1 packet wine yeast (like Prise de Mousse or
Montrachet)
Harvest grapes
once they have reached 22 to 24 percent sugar (22° to 24° Brix).
Sanitize all
equipment. Place the grape clusters into the nylon straining bag and
deposit the bag into the bottom of the food-grade pail. Using very
clean hands or a sanitized tool like a potato masher, firmly crush
the grapes inside the bag. Crush the campden tablet (or measure out
1 teaspoon of sulfite crystals) and sprinkle over the must in the
nylon bag. Cover pail with cheesecloth and let sit for one hour.
Measure the
temperature of the must. It should be between 70° and 75° F. Take
a sample of the juice in the pail and measure the acid with your
titration kit. If it's not between 6 to 7 grams per liter then
adjust with tartaric acid.
Check the degrees
Brix or specific gravity of the must. If it isn't around 22° Brix
(1.0982 SG), add a little bit of sugar dissolved in water.
Dissolve the yeast
in 1 pint warm (80° to 90° F) water and let stand until bubbly (it
should take no more than 10 minutes). When it's bubbling, pour yeast
solution directly on must inside the nylon bag. Agitate bag up and
down a few times to mix yeast. Cover pail with cheesecloth, set in a
warm (65° to 75° F) area and check that fermentation has begun in
at least 24 hours. Monitor fermentation progression and temperature
regularly. Keep the skins under the juice at all times and mix twice
daily.
Once the must has
reached "dryness" (at least 0.5° Brix or 0.998 SG), lift
the nylon straining bag out of the pail and squeeze any remaining
liquid into the pail.
Cover the pail
loosely and let the wine settle for 24 hours. Rack off the sediment
into a sanitized one-gallon jug, topping up with a little boiled,
cooled water to entirely fill the container. Fit with a sanitized
bung and fermentation lock. Keep the container topped with grape
juice or any dry red wine of a similar style. After 10 days, rack
the wine into another sanitized one-gallon jug. Top up with dry red
wine of a similar style.

After
six months, siphon the clarified, settled wine off the sediment and
into clean, sanitized bottles. Cork with the hand-corker.
Store bottles in cool, dark place and wait at
least six months before drinking.
Red wine is fermented with the pulp and skins.
This "cap" will rise to the top, so you need to "punch
it down" frequently with a sanitized utensil.
Dry White Table WineIngredients
18 lbs. ripe white
grapes
1 campden tablet
(or 0.33g of potassium metabisulfite powder)
Tartaric acid, if
necessary
Table sugar, if
necessary
1 packet wine yeast (like Champagne or
Montrachet)
Harvest grapes
once they have reached 19 to 22 percent sugar (19° to 22° Brix).
Pick over grapes, removing any moldy clusters, insects, leaves or
stems.
Place the grape
clusters into the nylon straining bag and put into the bottom of the
food-grade plastic pail. Using very clean hands or a sanitized tool
like a potato masher, firmly crush up the grapes inside the nylon
bag.
Crush the campden
tablet (or measure out one teaspoon of sulfite crystals) and
sprinkle over the crushed fruit in the bag. Cover pail and bag with
cheesecloth and let sit for one hour.
Lift the nylon
straining bag out of the pail. Wring the bag to extract as much
juice as possible. You should have about one gallon of juice in the
pail.
Measure the
temperature of the juice. It should be between 55° to 65° F.
Adjust temperature as necessary. Take a sample of the juice in the
pail and use your titration kit to measure the acid level. If it is
not between 6.5 and 7.5 grams per liter, then adjust with tartaric
acid as described above.
Check the degrees
Brix or specific gravity of the juice. If it isn't around 22° Brix
(1.0982 SG) adjust accordingly.
Dissolve the
packet of yeast in 1 pint warm (80° to 90° F) water and let stand
until bubbly (no more than 10 minutes). When it's bubbling, pour
yeast solution directly into the juice. Cover pail with cheesecloth,
set in a cool (55° to 65° F) area and check that fermentation has
begun in at least 24 hours. Monitor fermentation progression and
temperature at least once daily.
Once the must has
reached dryness (at least 0.5 degrees Brix or 0.998 SG), rack the
wine off the sediment into a sanitized one-gallon jug, topping up
with dry white wine of a similar style. Fit with a sanitized bung
and fermentation lock. Keep the container topped with white wine. Be
sure the fermentation lock always has sulfite solution in it. After
10 days, rack the wine into another sanitized one-gallon jug. Top up
with wine again.
After three
months, siphon the clarified wine off the sediment and into clean,
sanitized bottles and cork them.
Store bottles in cool, dark place and wait at
least three months before drinking.
