White Labs Brewzyme-D

Brewzyme-D stops diacetyl in its tracks! It converts the compounds that form diacetyl into a flavorless compound. Take the guesswork out, make great lagers, help out lazy English strains, and protect yourself from hop creep in your IPAs. One 10mL vial is good for 5 gallons (20L) of wort.

Directions: Add 10mL of Brewzyme D to 5 gallons of wort at yeast pitch and ferment normally. OPTIONAL: If making an IPA with a large dry hop charge, add 10mL with the dry hops to prevent diacetyl formation from hop creep. 

Dosage: 10mL for 5 gallons (20L) of wort at yeast pitch. 

• Store in the refrigerator between 33-50F
• Working pH: 4.0 - 7.0 
  
• Shelf life is 18 months from the date of manufacture
  
• Made with ALDC - alpha acetolactate decarboxylase - the same powerful enzyme used in commercial breweries. 

Note, Brewzyme-D will not remove existing diacetyl, it is a preventative.
