Cold stabilization at Fielding Estate Winery

Riesling fun fact: Riesling often undergoes a process called cold stabilization.

It is a method used to remove insoluble deposits in the wine before bottling. The wine is stored after fermentation at a temperature just above freezing in metal tanks for one to two weeks until the majority of tartaric acid has crystallized. These crystals appear when the wine is exposed to cold temperatures. Although these crystals (often referred to as “wine diamonds”) are safe for consumption, consumers may find them to be unattractive or mistake them for broken glass. After this procedure is completed, the wine is filtered to remove any remaining yeast or impurities.

So since these crystals are harmless, is cold stabilization an unnecessary process or is it completely essential? I personally prefer a smooth, sediment-free glass of Riesling. ANUPA SIMON
