What are Wine Diamonds?

All wines can produce small tartaric crystals if chilled, known as “wine diamonds”. This is, in fact, a very natural phenomenon that occurs in wines made with fresh must.  If you wish to prevent this, you may chill your wine in the Carboy by placing it in a cool temperature and let the crystallization process occur before bottling. For white wines only, we recommend the use of Kristalblok®, a completely natural crystal blocker. DO NOT use in reds or rosés. The tannins of red wines will react with the Kristalblok® and make the wine hazy and unfilterable. The use of Kristalblok® will NOT alter the taste of your wine.
