Maxi Biab And Post Boil Dilution

[Truman42]

Not wanting to bag anyone out (because I respect BIAB, after my brew effort last night without it), but....

Have you thought about obtaining an extra pot from Big W (especially on special - my 2nd was $12) and doing a double stovetop? It's my "standard" method.

It means that the strike water heats quicker (heating 2 x 8.5L, is quicker than heating 14 or 17 L, nor do you need to "top up"), and you've got the head room to really give it a good sparge.

Obtaining boil is easy as well.

The only downside is a higher loss to trub (by virtue of 2 pots with an inch in each), but in terms of chasing extra efficiency, it's somewhat offset by the extra ability to sparge.

Mate I have an 18 litre urn and a 20 litre BigW pot...But Ive just moved house and we have an induction cooker and the pot doesn't work because its aliminium. That and the missus wont let me brew inside anyway. So until I get a burner Im stuck with just the urn.

Ban her from beer until she lets you. Mine started up and I told her that if she kicks me out, she gets no beer.

Works too! :lol:

Ha ha Yeh good idea I might try it. Dont think it will work though..LOL

i put my recipe into brewmate and it says to use 2.6kgs to 12L of water for an abv of 4.5% is this correct from what ive read it should be 4kgs of grain to 13L of water.

Craigo,

The 4kg of grain is for between 19 and 23 litres.

Basically you make a higher concentrated Wort (1.060 to 1.070), and then dilute it to your required OG.

I do my calculation in BrewMate using 21 litres, then use that OG as my target when diluting. If my efficiency was down, I dilute less, and end up with less into the fermenter. If the efficiency is up, I can chose between more into the fermenter at THAT OG, or 21 litres of a higher OG.

EDIT: Just checked my notes, and I was slightly wrong in my earlier post. I have successfully used 5kg of grain in my 13 litres, and only dropped a few points in efficiency.

oh ok thanks that makes sense
