Endozym Thiol Rouge is a specific liquid enzymatic preparation for the expression of thiol aromas of red vines, such as: Grenache, Merlot, Cabernet franc, Cabernet Sauvignon, Syrah, Mourvedre, Cinsault etc. The utilization of Endozym Thiol Rouge facilitates the extraction and dissolution of the compounds present in grapes, including aromatic precursors and varietal aromas. Endozym Thiol Rouge releases these compounds from grapes by weakening the pectic chains and acts towards the secondary activities together with yeasts during fermentation.
