My latest lager has just finished and, for the first time, I'm thinking of doing it properly and bulk lagering - but I don't have a brew fridge. Locations cool enough seem to be the garage or the loft, but I'm a bit worried about rodents - we live in the country and they seem to eat through everything, they got through thick plastic to get to some peanuts. Anyone know if they'd likely try to get into an FV for the beer?
