When you poured in the dry yeast, a few particles must've stuck to the glass. Since it's a warmish damp environment in there, they absorb some water and voila, weird spots on the glass.
That's what happened to! When I first put in the yeast, some of it got stuck on the side. I guess the residual yeast just multiply on the glass and form glob colonies. Ahhh, well thank you guys for the relief. Being the first time I've ever made any alcohol at home, I get nervous from every little thing. Can't wait to enjoy my brew!!
Off topic: how long do you think it'll take for the fermentation to complete (ready to drink)? Thanks!
