Do wine kits impart the same health benefits as regular wine?
Dave

Yes, almost all the health benefits of wine is linked to the
polyphenol content of wine. there may be a slight effect due to the
alcohol and yeast byproducts as well.

All of which are in kits as well as wine from fresh grapes.

If anything, the kits may have more stuff: the comercial wine is often
filtered.

The kit wines are usually made from a mix of concentrated grape juice
and invert suger added.

Obvoiusly this is worse than wine from pure grape juice, as its
somewhat bulked up with suger, and it's usually the lesser standard
grapes that go into concentrate rather than wine, but these damaged
grapes contain higher concentrations of many polyphenols. However,
concentrate is made by heating the grapes which chemically changes the
grape juice.

The packets of 'not from concentrate' grape juice that you purchase in
the supermarket are usually filtered to remove tannin found in the
grape skin, so people can drink it without a astringic aftertaste - So
Red grape juice, which is not a fermented beverage, is not a
significant source of resveratrol or polyphenols.

In fact, you have to add tannin back to simulate the grape skin
bitterness if making wine from this source.

The mechanisms behind the health effects - and the effects are visible
in large population studies, are gradually being unpicked, but the key
compounds so far are Resveratrol (a polyphenol) and more antioxidants,
the flavonoids.

You can eat grapes, and eat other sources high in resveratrol -
peanuts, mulberries, cranberries, blackberries etc.. are also good
sources.
Genrally a a lot of the polyphenol compounds are in tomatoes, peppers
and other vibrantly coloured fruit and veg.

The amount of resveratrol (trans-resveratrol) in peanuts ranges from
0.02 to 1.79 micrograms per gram. A 100g serving delivers about 100
mcg.
Red wine contains from 0.6 to 0.8 micrograms per milliliter, a glass of
red wine delivers on the average, between 600 to 700 micrograms of
resveratrol, 6 times more than peanuts.
Fresh grape skin, has approximately 50 to 100 micrograms per gram. So a
tablespoon full of freash grape skin provides the same as a glass of
red.


To make wine for the heath effect - I guess the best way would be to
get a few baskets of grapes from a fruit wholesale source, and press
your own red wine.
However, a few glasses a week in addition won't harm, and unlike juice,
wine keeps for years, and you get a benefit from the alcohol.

You could also make a country wine from berries, like
blackberry/blueberry/mulberry wine and should get a similar effect in
terms of the greater health benefits.

The polyphenol Resveratrol is increasingly deemed to have a number of
potentially beneficial properties, including antioxidant,
anticoagulant, anti-inflammatory and anti-cancer effects.

This reply is so good and knowledgeable that I am glad that I provoked
it.
