Calcium L-Tartrate Hydrate – Wine Stability Reagent 100g

A high-purity crystalline compound used in winemaking laboratories and quality control to assess and manage calcium tartrate stability.

In wine, calcium and tartaric acid can combine to form calcium tartrate crystals, which may precipitate in bottle over time. This product is used as a seeding agent to trigger and evaluate this instability before bottling, allowing winemakers to identify and manage potential crystal formation.

Supplied as a fine crystalline powder, it is suitable for laboratory testing and controlled stabilisation procedures.
