Two products that could help winemakers produce significantly better wines should prompt wineries to seek approval from the Alcohol and Tobacco Tax and Trade Bureau (TTB), which has not fast-tracked these items.

The first is Zenith, a colloidal material that will cold-stabilize both white and red wines permanently. Enartis developed the product and introduced it at this year's Unified Wine & Grape Symposium.

The second is a bacteria, Lactobacillus plantarum, that can consume malic acid to finish malolactic fermentation (MLF) more quickly and completely and with fewer side metabolites. L. planetarium is approved internationally for use in wine and in the United States for beer, but not for wine.
