Just looked at one of the larger on-line brewing supply sites and the prices for liquid yeast are up quite a bit. What gives? I know it's been maybe 4 or 5 months since I purchased liquid yeast but from a LHBS - my last on-line liquid yeast purchase was probably a year ago but I remember the prices being around $7 to $9. It's more like $10 to $12 now! What happened?!!
