its not new, I've had it for 5 years now and use it for all sorts of things. I'm just going to boil the hell out of it just to make sure it doesn't impart any off flavors. Just trying to save some money up before buying a nice kettleI've never used aluminum, but it should be ok. Is it new, or has it been used before for something else? If it's new, season it by boiling water for a while.
So my kettle is 7.5 gallon. I eventually want to work my way up to BIAB in the next couple weeks, with that I am a little worried with boiling over especially when adding hops or the hot break. Is it a good idea to boil with a lower water volume and then add more towards the end of the boil?My BK is a 12 gallon aluminum kettle from Costco, and it does very well. Although depending on the batch size you are planning, 8 gallons is a little short. If you're only doing partial mash or extract, you're fine. Just don't plan on doing more than 7 gallons (at the start of boil) or you'll have a big mess on your hands (and stove, and floor, and whatever else might be in the way), unless you do a VERY gentle boil. Contrary to popular belief, you don't need a super vigorous boil to get the most out of hops, or your wort. And you can always turn up the heat once the volume is down enough.
I personally do that all the time. I've been producing three gallon batches BIAB on my stove with a four gallon kettle. It's trickier than BIAB is supposed to be, but very doable. I mash with less water than you would for full batch, then do a type of "sparge." Still a little short, I wind up adding a little water right at flameout to reach the desired full volume. It helps that my stove doesn't produce a very raucous boil. (Throttling back the heat might help in your case too. ) Even with all the monkeying around, I wind upSo my kettle is 7.5 gallon.
