BIAB with 20 litre pot?

[Paddy Bubbles]

Howdy. I've acquired a 20.5 litre stockpot which I intend using for extract brews. However, I'd like to try my hand at a grain brew using the BIAB system at some stage. What's the maximum amount of wort I could get out of a stockpot this size, using BIAB?

Thanks.

Some great info there! Looks like what I'm after is a Mini-BIAB:

This guide describes the making of All- Grain beer with the most basic, domestic kitchen equipment with no complicated processes whatsoever. This is the simplest BIAB anyone could possibly undertake, but it nevertheless has the potential to produce some of the finest beer.

Experienced all-grain brewers should also consider using this method to brew small batches of experimental beers.

In this guide, we will use a 19 litre pot to brew 9.5 lts of American Pale Ale - NRB's All Amarillo APA.

I have a similar pot to you, I started off doing mini-BIAB and then moved on to maxi-BIAB to get 20+ litre brews using the same pan. There's information on this method on the biabrewer site but it basically involves a sparge step and a post boil dilution in the fermenter. Do a couple of mini brews first and then you might feel like doing the maxi method - you get twice as much beer for essentially the same effort.

i have easily done 23 litres in the fermentor with 20 litre pot. just follow normal recipe and chuck in additional water into fermentor.

i am sure you could probably get to 25 with a push.

Hi Paddy,

The change from extract to BIAB is well worth it. I noticed a big step up in taste and a big step down in cost. Dont know if other people feel the same but BIAB produced far better beer for me.

This is what I'd do if you want to get the maximum amount of beer per brew, check your hop utilisation though as you may need to bump up the amounts by a few grams.

The guy (Ralph) who is the "maxi BIAB" master is actually a good mate of mine and we meet up for a curry most weeks as well as being in the same brew club. His beers are prize winners and if I had my time over again and hadn't gone electric Urn I'd probably have gone with a large stockpot and gas burner. Recommend that BIABrewer.info site.

When you think about it, at its most basic it's not unlike using an Electrim in the sense that you can mash in it, you can boil in it, but you do need a sparge step along the way to get a full batch with reasonable efficiency.
