When using bentonite post-fermentation (sometime for fruit and whites), I let it settle for a week or 2. A lot depends on thick the gross lees is -- if it's rather thick I'll rack sooner to get it out, but I want to rack only once so it's a trade-off. I add K-meta once fermentation is done. This is at each racking and every 3 months during bulk ...

In the next series of experiments, a mixed culture of all tested strains was immobilized on a mineral carrier being a mixture of perlite and bentonite (20:80 by weight). That mixed culture applied for PM deodorization was particularly active against ammonia and hydrogen sulfide, which were removed from the exhaust gas by 20.8% and 17.5% ...

After fermentation is complete, bentonite can be used to stabilize a wine by aiding in protein, phenolic and yeast sediment suppression. To use bentonite, begin by stirring a 25-50g powdered bentonite slurry into a few liters of room temperature water. Allow the slurry to stand for at least an hour before adding the slurry to your wine.

Hi, I'm brewing my first batch of mead and am done with the second fermentation. I'd like to clear the mead with bentonite. The package says mix 2 tsp. bentonite with 1/2 cup water for 5 gallons. Should I divide exactly by 5, or is 1/2 tsp. bentonite to 2 tbsp. water close enough? Thanks.

Pectolase is, of course, added before fermentation. Bentonite has several effects: it can adsorb some components and reduce color, but also remove things you want, such as your enzymes. In practice, though, bentonite is mainly used a flocculant, and flocculation / clarification don't make much sense before the fermentation is complete. ...

Add the hydrated bentonite to your wine before fermentation begins, and stir thoroughly to ensure it's evenly distributed. When working with fresh grapes for red wine, the process of adding bentonite does indeed require a bit of a different approach. Since it's challenging to stir the bentonite into the crushed grapes directly, it can be …
