Brettanomyces Control with Chitosan
No Brett Inside is an effective tool to control Brettanomyces in the cellar. Comprised of a natural polysaccharide from Aspergillus niger (same organism where oenological enzymes are sourced), No Brett Inside has been shown to reduce Brettanomyces populations from 3 x 105 cells/mL to 0 after 10 days of treatment.
No Brett Inside can be requested for use by the TTB under 24.249. An approval letter from the TTB is neccesary before use on commercial/production wine. A draft letter is available below. At this moment all commercial use must be accepted by the TTB prior to addition to wine. Please speak with us for more information regarding laboratory or production trials.
RECOMMENDED DOSAGE
4-8 g/hL (40-80 ppm) or 0.33-0.67 lbs/1000 gal
DIRECTIONS FOR USE
Prepare No Brett Inside by suspending it in 5 times its weight in water. Additions can be made during pump-overs or during tank/barrel agitations/mixings. Let the No Brett Inside settle for 10 days, then rack off.
Please note: No Brett Inside can reduce Brettanomyces populations in wine but it has no impact on 4EP or 4EG levels already present in the wine.
Recommended Dosage
4-8g/hl
