Intermediate beer brewer, relative newbie to wine. I started a Shiraz from a kit tonight (Heron Bay).
There's 6 gallons of it in my 6.5 gallon plastic primary fermenter. The instructions say "cover loosely" but this is not possible due to two curious cats who have the run of the house. (Also I'm not sure what exactly "cover loosely" means -- just lay the lid on top with no seal??)
Right now I have the plastic lid on tightly, with a 3-piece airlock in place. Is this enough or should I be doing something else to avoid a popped airlock/lid or explosion? Are blowoff hoses appropriate for wine? I've never used one and I'm a bit concerned about that approach (again, the cats will get into it).
