I decided to try the bentonite in the first fermentation by starting a new batch. I'm trying a few ideas I saw on YouTube, including adding a pectic enzyme to juice, tea (made with three tea bags), and the baking yeast from City Steading's grape juice wine. I started with a 1.100 as of typing this.

In very clear musts, bentonite may improve fermentation kinetics, but in wine, it also increase H2S production. I'm not sure if it occurs the same way in mead, but keep alert for the possibility. A big negative is that using it during fermentation in wine making means that you cannot age the wine on the lees as the bentonite treated lees will ...

Hydrochloric acid was used to prepare bentonite carrier for xylanase immobilization from Trichoderma reesei as green biocatalyst. The process to produce xylanase from Reutealis trisperma was carried out for 72 hours in batch fermentation at initial pH of 6.0. The xylanase activity was 205.9±0.84 U/mL.

White wines with developed protein haze are perceived by consumers as faulty (Marangon et al., 2013).The formation of haze originates mostly from the presence of thaumatin-like proteins and chitinases, which therefore need to be removed by fining before wine marketing (Marangon et al., 2011).Bentonite is still the most efficient fining agent in achieving protein …

You can add bentonite before or after fermentation or both.

Bentonite also eliminates protein haze, which was a problem in early kits. Timing — In my example, I added bentonite post-fermentation because that was my need at that time. Next year, assuming I make Vidal again, I may add the bentonite pre-fermentation. The timing of the addition depends upon the situation and the winemaker's need.
