The beer is fermenting happily in its 30 litres plastic bucket, and I was planning on racking it to a secondary fermentation 30 litres plastic bucket. The problem is, the beer is 20 litres and the bucket is 30 litres, leaving 1/3 of the volume of air. I'm heard that secondary fermentation shall minimise the volume of air because of infection problems. What's my best option ?
- too dangerous, don't rack it for secondary and leave it one more week in the primary bucket ?
- or rack it anyway in the big bucket, with careful sanitation, and leave it in a cool place for three more weeks ?
I promise I did make a comprehensive search in the newsgroup before asking this question !
Thanks,
