A BEGINNERS GUIDE FOR HOME WINEMAKING IN BERRIEN COUNTY, MICHIGAN
AND OTHER NORTH AND CENTRAL STATES  (rev. 7/91, 2nd edition)



Introduction

     Berrien County abounds in fruit of all kinds suitable for winemaking.
Good wine can be made from virtually any fruit, although some make better wine
than others.  Fruits can even be combined, so that they compliment each other.

     Berrien and neighboring counties host Michigan's most famous wineries,
including Tabor Hill and St. Julian.  Therefore, wine grapes are also avail-
able locally.  An Italian hybrid, Vidal, and a French hybrid, DeChaunac, are
two examples of premium wine grapes usually available the 1st week of October
each year.  Another red, Foch, is also sometimes available, but not every
year.   Other reds are becoming available (i.e., Chancellor and Chambourcin).

     Winemaking supplies are available locally as well.  In St. Joseph,
Lambrecht's liquor store has everything needed to set up a home winemaking
operation.  Additional supplies are available by mailorder, such as Ken's Wine
Supply (now known as Diversions Inc.) in Traverse City, and Cask & Keg in
Mattawan.  Out-of-state suppliers are numerous.

     The Federal Government allows home winemakers to produce, tax-free, up to
150 gallons of wine per household per year.  Wine may be used by the immediate
family only, and may not be sold.  Commercial wineries must be licensed and
bonded, and are taxed by the Inernal Revenue department.

     Wine is a healthful beverage taken in moderation.  It is probably man's
oldest fermented drink, mentioned frequently in the Old and New Testament of
the Bible.  Its health benefits were confirmed by Apostles Luke and Paul, and
are supported by modern medical science.  Wine has anti-viral properties, and
was used as an antiseptic in Biblical times.  Everyone knows the enjoyment a
good wine adds to meals.

     Wine can be made at home easily, and with great economy.  The equivalent
of a six-dollar bottle of fine table wine can be made at home for about 90
cents in materials cost.  Equipment required is reusable indefinitely, and
inexpensive.  All else needed is a little space, instruction, and patience!

Getting Started

     In the beginning, you will need to buy the following:

     o    Five-gallon glass watercooler bottles, 2 minimum
     o    Fermentation locks, one per bottle
     o    Size 6 1/2 center-hole white rubber stoppers, for above
     o    Plastic tubing, 4 feet, food grade vinyl (or syphon apparatus)
     o    Brix or Balling hydrometer (saccharometer)
     o    Liquid thermometer, immersion type
     o    Cork inserter and wine bottle corks (no taper)

     It will also be very handy to have the following:

     o    A sturdy bench or table (supporting 200 lbs or more)
     o    A 20-gallon plastic bucket or trash can
     o    A plastic yard-trash bag or Visqueen roll
     o    A wooden spoon or paddle 2 feet long
     o    Lots of empty (cleanable) wine bottles

     Obviously, you will need a place to set-up your equipment.  The ancients
used cellars and caves, and with good reason.  The earth provided a constant-
temperature environment:  not too cold in winter, not too hot in summer.
Modern man has his basement, which often is sufficient to provide the same
function.  What you want is as constant a temperature as practicable, between
60 and 80 degrees F.
     Why is this so?  Because wine is a delicate thing that spoils in the
heat, and quits fermenting in the cold.  Average room temperature is therefore
best.  If you have a basement, put your equipment in it near a sink, such as
found in the utility room, because you will need a source of hot running water
handy to wash things out.

Making the Wine

     So now you have all the equipment.  Next, you must decide what kind of
wine you want to make.  The best way to start is to make wine from the clean
juice of wine grapes.  There still exist a few farmers who press, filter and
cold-tank such juice from one or two varieties;  for a few dollars a gallon,
they will fill up your 5 gal. container.  If special arrangements are made, a
few wineries will do this also.  Place your order well in advance!

     The easiest juice to get is Vidal.  Others may also be available.  NOTE:
Get Concord juice only as a last resort, because it will not make good wine
all by itself; it needs skillful blending, dilution, and manipulation to make
it into something palatable (and then only as a dessert wine).  You might try
Niagara, though (Concord's white brother).  Dilute the juice 25% first.

     Once you get the juice, you must immediately begin the winemaking process
or else it will spoil, or produce inferior results.  Therefore, before you go
to the vineyard, be sure to stock up on these supplies:

     o    Granulated sugar (cheapest available), 10 lbs or more
     o    Montrachet or other wine-yeast packets, 1 per batch (Lambrechts)
     o    Potassium Metabisulfite (Lambrechts)

     After you have all these things listed above, your equipment, and your
juice, you are ready to begin-

The Fermentation

     Fermentation is the process whereby the yeast cells change the sugars in
the wine to alcohol, carbon dioxide, and esters.  Many other chemical changes
occur as well.  Bacteria also accomplish a tertiary fermentation, discussed
later.  Right now we are concerned with the yeast.

**Note:  some feel that the Pasteur Champagne strain of yeast works best for
white wines, and the Montrachet strain works best for reds.  My experience
does not bear this out, although Montrachet sometimes "flavors" a delicate
wine.  There are many other strains you can try, too numerous to mention.  Ask
your supplier for his recommendation!

                         JUICE FERMENTATION PROCEDURE

     Step 1:  Immerse the Brix hydrometer in the grape juice, which should be
     at about 60 degrees F.  Read the number on the Brix scale which is at the
     liquid level.  For Vidal, it will be about 18-20;  for others, about 16.
     Transfer the juice to your Primary Fermenter (new trash can).

     Step 2:  Stir-in sugar to raise the Brix (sugar %) reading to about 24.
     This will take up to 1 pound per gallon of juice for initial Brix of 16.
     Do it gradually, and check the reading frequently during sugar addition.
     It may take up to 15 minutes of continuous stirring to dissolve 5 lbs of
     sugar in 5 gallons of juice.  Alternatively, you could heat the juice up
     to about 94 degrees F (in a new pot) to speed this process.

     Step 3:  Once the Brix is at 24 or thereabouts, add 1 packet Montrachet
     wine yeast per 5 gallons of juice.  Follow directions on the packet.  Do
     not use common baker's yeast.  Stir well for five minutes, and cover with
     a sheet of plastic.  Clear sheet, such as Visqueen, lets you observe the
     action.  Alternatively, use the lid that came with the trash can.

Within 24 hours, something very exciting begins to happen.  The mixture of
juice, sugar, and yeast, now referred to as "must", is now in primary
fermentation.  The must fizzes like an Alka-Seltzer tablet, and gives off
fascinating aromas.  It may even "boil", tossing up blankets of foam.  Once
this process begins, you must stir the must twice daily to keep the yeast
cells in suspension and add oxygen.  After the end of five days, discontinue
stirring.  You will find the action has quieted down:  the must is going into
secondary fermentation.

     Step 4:  Wash out your 5-gal glass water bottle with a strong solution of
     Potassium Metabisulfite in hot water.  Drain the solution out completely,
     but do not rinse.  Transfer the contents of the primary fermenter to your
     5-gal glass water-bottle.  Do this by syphoning with the clear plastic
     tubing, keeping the end of the hose about one inch off the bottom of the
     Primary Fermenter.  This avoids transferring unwanted sediments into the
     bottle.  This syphoning/transfer process is called "racking".  Make sure
     must is no more than 2 inches from the top of the bottleneck.

     Step 5:  Attach Fermentation Lock, with white-rubber plug, to the top of
     the bottleneck.  Wash the plug and Fermentation Lock (bubbler) in the
     Potassium Metabisulfite solution (mentioned above) first.   Fill the
     "bubbler" 1/3 full with water, adding a few crystals of Potassium Meta-
     bisulfite to the bubbler to avoid molds.

     Step 6:  Place the Secondary Fermenter (the above apparatus) in a place
     where the temperature will remain between 60 and 85 degrees F for the
     next nine months (closet, basement, etc.) but near a sink.  The secondary
     fermentation will continue unassisted for at least three months.  Observe
     the action of the "bubbler".  You will notice it is slowing, and may even
     stop completely.  You will also notice a layer of sediment has built up
     on the bottom, up to an inch thick.  This is dead yeast and suspended
     matter from the juice, and is called "lees".  It's not a good idea to
     leave the must "resting on its lees" for a long time though, which brings
     us to the next stage of the winemaking process.

Purification

     This stage is what takes the longest and is definitely the most frus-
trating part of winemaking.  There is nothing the amateur can do to hasten
this process, without the end result being something less than real wine.  It
will take at least a year for must to be transformed into something drinkable.
Many wines need an additional year in a corked bottle to be at their best;
some, two years or more.

     Commercial wineries use filtration under pressure, centrifuging, and even
ion-exchange to hasten wine development.  This can remove character, and is why
good home-made wine will often taste better than commercial.  Chilling clear
wine at 25 degrees F may buy you a month or two, and helps remove harsh tartaric
acid by crystallization.  Put the bottle in the garage in wintertime for a week
or two, but watch the temperature!  If it gets colder that 15 degrees, it may
freeze and crack your bottle, thus losing the batch.

     Time is the best purification method for home winemaking, coupled with
regular, careful, racking.  NOTE:  WAIT UNTIL AFTER SUMMER TO BOTTLE YOUR
WINE, OR THE BOTTLES MAY EXPLODE IN THE SPRING, WHEN TERTIARY FERMENTATION
BEGINS.  More on this later.


     Step 7:  After the wine has nearly cleared itself (after about three
     months), place the secondary fermenter on a table.  Try not to jostle it
     and stir up the lees; if this happens, let it sit awhile until it
     settles.  Remove the bubbler & plug assembly, and carefully insert your
     plastic racking tubing.   Make sure the end is not in the lees, but over
     it.  Start the syphon at the other end by suction, and rack all the clear
     must to an identical bottle that has been washed-out with Metabisulfite
     solution as in Step 5, and re-attach the bubbler as before.  Make sure it
     has water in it.

     At this point you will have a bottle of clear or nearly-clear must.  It
might look good enough to drink, but it isn't.  There is far too much harsh
acid and bitter yeast cells in it to be tasty.  Taste a little and see;  you
won't believe the difference six months from now.

     By the way, make sure after racking that all semidents and lees are
washed-out of the first bottle as soon as possible after it is emptied.  Also,
make sure the liquid level in the new bottle is two inches from the bottom of
the stopper.  The secondary fermenter must have as little airspace as possible
in it, while allowing room for expansion due to temperature changes.  It is OK
to add some storebought white wine to the bottle to make-up for any lost
during racking (or, plain water can be used if less than a pint).

     The above racking steps will need to be repeated about three times more
before bottling, as follows:

     Step 8:  If you chill the must during winter, rack it again just before
     spring to get rid of the crystallized excess acid ("gravel").

     Step 9:  Watch the liquid level carefully when Springtime finally
     warms-up the bottle.  It may have to be lowered slightly to avoid having
     it go up into the bubbler and spoil.  Insurance:  add a little Meta-
     bisulfite to the water in the bubbler after racking each time.

When the bottle warms-up in late spring or early summer, it will "come alive"
again with renewed action.  This almost always happens.  This can be caused by
leftover sugar in the must, or by what is called "Malolactic Fermentation";
the must having gone through Primary and Secondary, it is now going through a
Tertiary Fermentation.

     Malolactic fermentation is a process whereby certain bacteria in the must
convert excess malic acid to lactic acid. Lactic acid is much smoother tasting
in the wine than either malic or tartaric, present in the beginning.  This
process creates gas, which can cause prematurely sealed bottles of wine to
explode.  This is what the earlier warning was for.

     How can you tell when malolactic is over?   The scientific way is to
perform a total acidity titration several times over the course of the
fermentation.  When the reading falls and remains low, then malolactic is
presumed finished.  But the amateur need not do it this way; it is possible to
determine by observation (when the springtime bubbles stop) and tasting (when
the harsh sourness disappears).

     The final stage in purification is called "fining".  This may or may not
be required.  If some slight cloudiness remains after all fermentation is
complete and the new wine is completely quiet, then fining is in order.  In
old times, the cellarmaster used the "candle test".  This involved placing a
clear bottle of new wine in front of a lit candle on a stand, in a darkened
room.  If the candle flame could be clearly perceived, with sharp edges all
around, the wine was deemed fine and ready to bottle.  Modern man can use a
narrow-beam flashlight.  The beam should not be seen in the bottle as it is
shone through for the wine to be judged "perfect".

     If the wine fails the above tests, it can be fined for maximum enjoyment.
Many fining agents are available:  Gelatin, egg-white, isinglass, powdered
nonfat milk, Bentonite.  Special gelatin from the winemaker's supply shop is
probably the safest thing to use.  Follow the directions on the package, and
wait two weeks for the wine to settle.  NOTE: if you don't care about sediment
forming in your bottles, omit this troublesome step.  Or, you could buy a
filter for about $80.  Commercial wineries usually filter the wine rather that
go through the delicate fining process.  But filtering can be tricky.

     Step 10:  Rack the wine one last time after fining to ensure purity.
     Follow previous procedure.  After a week or two of observation, the wine
     is finally ready for-

The Bottling Process

     There is some discussion on this subject.  Some say it is essential for
all wine to be bottled with corks, and some say it's OK to use screw-cap
bottles.  The writer believes in both: premium wine for long-term aging should
always be in a corked bottle, but fruit wines, white wines, and wines to be
consumed within a year of bottling should have no problems with screw-cap
bottles.  Evidently, the cork acts as a semi-permeable filter, releasing
volatile components to the atmosphere, but preventing air from re-entering.

     Step 11:  Obtain enough wine bottles for the entire amount of the batch.
     A standard 750ml bottle is one-fifth gallon, so you would need 25 of
     these for a 5-gal batch.  Wash the bottles with a non-scented detergent,
     rinse thoroughly, with hot water and Metabisulfite as a final rinse.
     Remove labels from bottles before washing!

     Step 12:  Make or buy your own labels, and attach to clean bottles.  Set
     up the racking syphon, as before, and fill each bottle to within 1/2 inch
     of the bottom of the cork (or stopper, or screw-cap).  A tubing pinchcock
     is handy to stop the flow while maintaining the syphon.  Note:  a special
     syphoning apparatus is available with a spring-loaded foot valve, which
     makes this bottling quick and easy.  You simply release pressure on the
     valve and the flow stops.

     NOTE:  Corks must be soaked overnight prior to insertion; other closures
     should be dipped in a bowl of hot Metabisulfite solution before use.

     Immediately after each bottle is filled, insert corks to 1/8 inch below
     top of bottleneck (a lever corker makes this easy) or attach screw-caps
     tightly.  You're done!

     NOTE:  Corks must be allowed to dry for a few days.  You may wish to put
     covers on them for a final touch.  Then, the bottles must be stored on
     their sides, so that wine may contact the cork.  Screw-cap bottles can be
     stored upright.  Check for leaks before putting on the covers!



                              RECOMMENDED READING

     WINE MAKING AT HOME
     by Homer Hardwicke

No longer in print, but usually found in public libraries.  Dated methods and
procedures.  Features 200 recipes for wines of all types, many fruits.  It's a
good, fundamental study in the art.  Author prefers late bottling and mostly
natural methods.  Glass jugs were not widely used at the time of writing.



     GRAPES INTO WINE
     by Philip Wagner

Modern, revised text.  Author is a professional winemaker and has his own
large-scale operation.  Tremendous amount of information;  a good "reference
book".  Author advocates heavy use of chemicals and early bottling.  Written
from a California winemaking perspective, notably differing from North Central
and Eastern climates.  Book is available in bookstores at the time of this
writing.


A FINAL NOTE TO NON-MICHIGANDERS:  All the things you've just read apply to
your state as well.  Winemaking supply stores can be found in most major
cities;  start by looking in your Yellow Pages.  Your supplier, once you've
found him, will be glad to tell you where grapes and juice can be found.  He
will also be happy to share his experiences in the art with you.
