Brewlength using a 25ltr boiler

[paulpj26]

I think I already know the answer to this question but I was wondering if there is anyway you can brew 40 ltrs with a 25ltr boiler? I'm thinking this is probably a really daft question and I will just need a bigger boiler lol but just on the off chance.....

you could do 2 x 20 litre batches

If you had a big enough mash tun you could do 20L of a very big beer (around 1.100) and dilute it down to 1.050 . . . . but its a tricky thing to get right. . . . Halite has a better suggestion as you do the second mash while the first is boiling, and then transfer the hot wort to a FV to cool, while the second is being sparged and boiled.

It adds a couple of hours to the brew day, and you have to get things right or you are juggling three things at once.

Thanks for the replies guys, I think you are right about doing two mashes the only problem is that i use my boiler as my HLT so I couldn't do both at the same time (sparge and boil). I might have a crack at doing a really big beer and dilute it down (is it just a case of adding water and taking hydrometer readings periodically?) . The reason why I asked was I've just bought a firkin from Barley Bottom and was wondering how to fill it lol probably should have bought a pin but as they were the same price the thought of more beer was too tempting!.

You don't need a hydrometer you can calculate it

Amount to Add = (Current Gravity * Current Volume / Desired Gravity ) - Current Volume

So If your wort (post Boil) was 1.096 and you had 21L, and you wanted it to be 1.052 it would be

( 96 * 21 / 52) - 21 = 17.75L Of Water to Add FOr a total of 21+17.75 Or 38.75L of Wort.

Or you can turn around and say I have 21L of Wort at 1.098 and I want 40L what is the final gravity

21 * 98 / 40 = 51 or 1.051 (Current Volume * Current Gravity / Final Volume = Final Gravity)

Cheers Aleman I'll try that :thumb:
