Link Posted: Sun May 06, 2012 12:12 pm Post subject: Hop alpha acid question |
|
|
I'm brewing 10g of Electric IPA today..my second brew on the new rig..last week was a stout..a particular favourite of mine... I brewed it first as sort of a control...because I'm not sure what effect all this great temperature control is going to have on an old recipe now I'm not using my old equipment.
For the IPA I couldn't get any Warrior bittering hops so have substituted Magnum instead.
I've adjusted the amount of hops to keep the alpha acid amount constant.
so..42.5g of Warrior at 15.8% now equals 52.9g of Magnum at 12.7% (1.5oz = 42.5g)
I can understand apportioning to keep the alpha acid content constant for bittering but not so sure about doing the same for flavouring or aroma.
I have some 15% Citra (and 3.3% Crystal) for dry hopping. Should I change the amount added to keep the AA amount constant?
What does everyone else do?

Thanks Kal....Looks like I'm 13g short of Centennial and Amarillo then for the last 5 mins...
I have some spare Challenger...would you substitute or leave as is..and make a note next time order more than 100g of those hops?

That comment could be interpreted as hopist, Kal!
I decided not to worry about it in the end..and make a note to order more hops for the next batch....
It's in the fermenter now....at bang on 1.065..
Gonna have a go at Pliny the Elder next if the Electric IPA works out..just trying to get my head around a £50 hop bill..
