I started my first brew about 3 days ago and there all bubbling away in my fridge and everything looks good , I just want to point out i forgot to take a hydrometer reading at the start of fermentation so i am not going to know the amount of alcohol in this brew . but The brew is a Lager brew and made with lager yeast, I am just wondering from when the bubbling ends how long am i looking before bottling my brew?
