I'm going to be brewing 5 gallon batches and I’ll be fermenting in the starter kit buckets. When I upgrade ( Xmas around the corner as is my birthday) should I ask for 7 gallon fermenters? Give myself a little room in case of a blow off (think i am using that term right) or in case i end up with a little more wort than I planned ( i have an 8 Gallon kettle) or would a 5.3 fermenter be 5 for a 5 gallon batch? Looking specifically at Speidals. Thankee sai.
