Hi! I started a blush kit (Vintners' Reserve) Thursday night. The directions did not say to use the airlock, but I did anyway because my husband makes beer, and he uses an airlock. I should've did more reading. Anyway, I had the lid tight, airlock on and it was bubbling away. I did some reading, and alot of literature said the wine needs O2, so I took the airlock off. It's day 4, I tested the SP, and it only change from the initial 1.85 to 1.80, and the kit says by day 5-7 it should be 1.01. Does this seem normal? Is there anyway to tell if I've messed it up? Thanks!
