Q:
We make three wines (Zin, P/S and Merlot) Our 2010 Zin and P/S have great aroma and taste but there is a sadiment in each glass, it apears as clear beads the size of sand. They are tasteless (?). Are these crystalls or what? And what did we do wrong? Paul

A:
We're no experts in this, but it seemed to be a matter of sufficient importance to justify some information-searching. Fortunately, this link turned up: http://wine-tasting-reviews.com/wine-basics-drinking-buying/open-wine/209-sediment-wine-decant-lees-tartrate.html

It sounds as if you just have some harmless potassium tartrate. You didn't do anything wrong. In fact, it sounds as if you did everything just right. Wish I were there to share some.
