We had a wonderful couple come in to the Andis tasting room
this weekend.
Both of them relatively new
to the appreciation and consumption of fine wine, they had previously been in
the winery and absolutely fell in love with the 2010 Andis Grenache.
A few nights later while enjoying the bottle
they had brought home with them they were very bothered to discover in the last
glass of the evening a bit of dark grainy sediment.
Wondering what had gone wrong they diligently
trekked back to the winery the following weekend (a tough assignment indeed) to
see what was amiss with the wine.
I was
very happy to be there to chat with them as we have found that sediment is one
of the most misunderstood aspects to wine consumption.
So I
told them the truth – “sediment happens”.
Here is the best explanation of bottle
sediment I have run across:
The tiny crystals you find in your
wine glass, and sometimes first in the wine bottle … are not only the least
likely to taste bad, but are treated by some as a sign of a better wine. So if
you find crystal sediment in your wine glass, there's no reason to worry or
fret.
The crystal sediment you might find in a wine glass is called tartrate and
forms from tartaric acid in grapes. Not all fruit has tartaric acid and its
presence in grapes is what allows us to make better wines from grapes than we
can from any other fruit. Because tartaric acid doesn't remain dissolved in
alcohol as easily as it does in grape juice, it binds to potassium after
fermentation and forms potassium acid tartrates — the crystalline solids
creating the sediment in your wine glass. Because red wines have probably been
exposed to cold temperatures less than white wines, they are more likely to form
tartrate crystals.
In theory all wines should probably form tartrate sediment, but modern wine
production has introduced cold stabilization and fine filtration which remove
most to all tartrates. More expensive wines that have been created according to
more traditional methods, thus eschewing cold stabilization and filtration, are
more likely to produce tartrate sediment. People who prefer the traditional
methods of wine production, which includes a lot of wine drinkers in France and
Italy, will treat the presence of tartrate sediment as a sign of quality.
The tartrate sediment in your wine glass or wine bottle won't hurt you if
you consume it and it isn't going to ruin the flavor of your wine, so you don't
need to worry about separating the crystals from your wine before serving and
drinking. However, there is also no value in consuming this sediment so don't
go out of your way to do so.

So not only is sediment not bad, it’s good!! Sure it is not the best to have a mouthful of
tartrate crystals as the final memory of a great bottle of wine, but, with some
gentle decanting and a little patience that is easily avoided. To me it is always a sign of a less manipulated,
less processed wine. And in the era of
mass production that is a nice thing indeed!
