## Questions & Answers

**Q: Is there an expiration date?  Is it good for more than 2018?  And does it require refrigeration, or just cool dark?  Thx**
A: Generally, we would recommend using the product within 12 months after opening. Refrigeration would be best, but is not required for storage.

**Q: What is the difference between A & B?**
A: AD332A has 12 grams of product while AD332B has 120 grams.

**Q: Do you add an additional 1.5 grams at 1/3 depletion? Or are you splitting the 1.5 grams? Also do you add it immediately?**
A: There are two schools of thought on this:
1. add at 24 hrs/48 hrs/72 hrs.  Less specific than:
2. add at yeast pitch/25% depletion/33.3% depletion.
YMMV

**Q: Fermaid o is manufactured by lallemand, but this listing shows the manufacturer as "cellularscience". who is cellularscience? is this genuine?**
A: I believe that Lallemand's smallest package size is 2.5kg. Cellularscience repackages the several products into smaller retail size packages.
