Bentonite for time‐saving use during fermentation, direct addition
FermoBent® PORE‐TEC is a very loosely granulated, extremely low iron and highly effective bentonite for juice treatment. It can remain in the tank during fermentation and is racked off with the yeast sediment at the end of fermentation. Direct addition facilitates a time‐saving working method during the harvest time.
Because it remains in the fermentation medium, it creates an inner surface which leads to even volatilisation of CO2 during fermentation and thus to an optimised fermentation process. FermoBent® PORE‐TEC has extremely low iron solubility. The long contact time between bentonite and the fermentation medium does not cause an increased need for blue fining in wine. The sediment is racked off with the yeast sediment, so there is no need for a separate step.
Benefits of Application:
- more thorough and selective adsorption of protein and impurities
- decisive for a clean flavor
- short settling time after fermentation
Varietals and vintages with moderate protein content-- 50-150 g/100L
Varietals with high protein content and pH values-- 200-300 g/100L
FermoBent® PORE‐TEC is added to the fermentation tank before the yeast and yeast nutrient. Before use the suspension should always be checked to ensure an untainted odour. The required quantity of FermoBent® PORE‐TEC can be added directly to the juice and mixed well. Swelling in five times the volume of water for 4 ‐ 6 hours is optimum. It must be mixed to distribute it evenly. Separate removal of the sediment is unnecessary because the bentonite sediment can be separated off with the yeast at the end of fermentation.Storage:
FermoBent® PORE‐TEC is a highly effective adsorption agent. It is therefore very prone to absorption of odours and moisture. This is why the product must always be protected against taint and moisture. Packs which have been opened should be immediately hermetically sealed. No liability can be accepted for improper storage and use.
