BIAB Size for 72qt

[TeiaMarcus]

Starting extract a few months ago, about 12 batches so far. Moving toward All-Grain and picking up hardware when I see a good deal. The goal is transition from extract to BIAB, then to All-Grain. My question....I am looking at a 19g/72qt pot. What size of bag could I use for that pot to make 5gal of brew? I want the larger pot so I have options for 10gal brews later when I move to All-Grain.... Responses are greatly appreciated...thanks!

First, a point of clarification. BIAB is all grain! Second, once you do BIAB, you may never want to go to a multi vessel set up because BIAB is so simple and FAST! Third, 5 gallon batches in a 19 gallon kettle are going to be interesting. I would suspect your boil off rate will be really high.

Now to your question. Your bag should be able to line the kettle and also drape over the lip on the outside so you can cinch it down so that it doesn't fall in. Which means your bag size is entirely dependent on your kettle dimensions. I would recommend hitting up @wilserbrewer for a bag or two. Reasonably priced and an exceptional product.

Yep. What he said. You can do it all with BIAB.

I would have one reservation about using too big of a pot fot the batch size. You may find you lose more heat during the mash as it will be more difficult to insulate with 10+gallons of headspace during a typical mash for 5.5 gallon batches.

I would look at a 15 gallon pot for 10 gallon batches. More user friendly for 5 gallon batches. i use an 11 gallon pot for 5.5 gallon batches. Holding temeratures is a cinch with a little insulation.
