Hi
about to put on a batch of coopers pail ale to natrerly condission in CUB keg, was talking at the HBS about only brewing a 40lt batch and part filling the 50lt keg, i eventully asked what would happen if i did a tripple batch and make it up to 50lt. 16.66lt ber can.
they said it could turn out great, but told me not to add any shuger/brew enhancer because the concentrate would eat itself and would be enouf. and allso that i should use some extra hops. It sounds like its going to taste verry verry beer'y, but could be good!
Is this true?
will it work?
what sort of %alckohole would i get?
do u reckon it will taste good?
would it take a long time to ferment?

If you add 3 cans to 50L of water with no other fermentables, you will end up with a very bitter mid strength beer.

Essentially, all you would need to do is figure out the recipe for one can at 22L, then double it, and fill to 40L. Then just throw in the 3rd can and an extra 10L of water and you are set.

Just for the numbers, if you added 3 cans and nothing else to 50L of water it would come out with an alcohol content of 3.9% and a bitterness of something like 28 IBU's (rough estimate)

If you add the 3 cans to 50L of water, plus 2kg of light dried malt extract, you would get an alcohol content of 5.4% and an IBU count of maybe 25 (i dont have a calculator for that handy)

Thanks rabbit,
I was a bit cautious about not adding shugar anyway, just wondering what a IBU is now though, and how it is calculated? It sounds like an interesting figuer!

IBU = International Bitterness Unit

One IBU is equal to 1 part per million of isohumulone, an acid (derived from hops) that provides the bitterness in the brew.

When you buy hops from a HBS, they come with an alpha acid percentage rating. You use that and your recipe, along with some nifty calculators available on the web, to determine how much bitterness X amount of that hop will provide when boiled for Y minutes.

thanks for that, im going to look into that now.

just put brew on, used 2.5kg of shugar, and 3 brew cans, made to 52lt, and spe gravity is 1.045, i was expecting this to be higher, as there is only 16lt per can, and a lot of shuger, do u reckon this is right?

holy crap! that's going to be some strong beer!

I hope so, im gunna crack it in allmost 2 months for a hell of a party!
Its bubling away right now, "like a open co2 tank dropped in a pool", its only on 20deg c, I allmost want to cool it downe, because it is so bloudy
vigerous
