Joenos WeinStabil Go, 100 ml Quick Test for Protein Determination

Protein in wine can later cause hazing, often only after bottling or during temperature fluctuations. WeinStabil Go is a quick preliminary test that lets you check, with white wine and light red wines, whether protein stabilization is needed before you reach for bentonite.

It works without a lab and without heating. At room temperature you mix bright-filtered wine with the reagent at a ratio of about 10 to 1 and observe the reaction. The stronger the haze, the higher the protein content. This way you avoid unnecessarily high bentonite additions and work more precisely.
