Is there an expiration date? Is it good for more than 2018? And does it require refrigeration, or just cool dark? Thx

Generally, we would recommend using the product within 12 months after opening. Refrigeration would be best, but is not required for storage.

What is the difference between A & B?

AD332A has 12 grams of product while AD332B has 120 grams.

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?

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

Fermaid o is manufactured by lallemand, but this listing shows the manufacturer as "cellularscience". who is cellularscience? is this genuine?

I believe that Lallemand's smallest package size is 2.5kg. Cellularscience repackages the several products into smaller retail size packages.
