JohnR13 Posted June 12, 2013 Share Posted June 12, 2013 G'day All, Have just bought some Cornelius kegs to start brewing with. Usually my brews are at around 23lt so if I drop back to around 20lt with the same ingredients is there an easy way to determine what ABV will be? Also I'll naturally carbonate so there will be .25% less than bottled as well. Cheers John Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted June 12, 2013 Share Posted June 12, 2013 Well you have a few options. It probably wouldn't add much though, somewhere between 0.5% and 1% I would guess. You could just leave it at 23 litres and bottle a few after kegging most of it. You could scale the ingredients back to give the same ABV in 20 litres as it does in 23 litres. If you've got IanH's spreadsheet or some other brewing software you could plug the recipe into them and get an estimated ABV. Or just brew it to 20 litres and take your SG readings, work it out from that and adjust ingredients to suit next time. Link to comment Share on other sites More sharing options...
Muddy Waters Posted June 13, 2013 Share Posted June 13, 2013 I don't really understand the question, or rather the reason you are dropping back your volume because you are kegging. The difference between bottling and kegging is small anyway. Maybe I'm just misreading. But, as Kelsey suggested, Ian's Spreadsheet is useful for playing with the numbers and seeing the effect.

Hairy Posted June 13, 2013 Share Posted June 13, 2013 I think John is changing his volume to only fill the keg. John, you can keep it at 23 litres and bottle the remaining beer after kegging. If you could be bothered. Link to comment Share on other sites More sharing options...
Muddy Waters Posted June 13, 2013 Share Posted June 13, 2013 Doh! I really need a day off as my brain is ceasing to function. It all makes sense now. John, I make most of my beers to between 21-22 litres and have found that after filling the keg I don't have enough left over to bottle (or waste [pinched] ). The balance is lost to trub.

I am a 21l brew man myself, and that volume fits nicely with two cans of malt extract and 250g to produce my desired ABV of around 4.2% kegged. However I find that I have enough for 2 500ml bottles after filling the keg to within 5mm of the gas dip tube. Although this varies, yesterday I kegged two 21l brews, I got the full litre from one but only 750ml of trub free beer from the other. Most times I get 1 litre.
