hey all -
i just brewed an IPA that calls for 2 ounces of Cascade hops after 7 days in the primary. the recipe i was using was for a 5 gallon batch, but i ended up doubling the recipe to 10 gallons. can i just add 4 ounces of hops, or is it more complicated than that? i know that doubling a recipe isn't always as simple as just doubling the malt/hop bill...
thanks for your help.
You are correct in that doubling isn't always that simple but at the home brew scales we make beer, it's not as big of an issue. It's not an issue whatsoever with dry hopping. Just double it or go moar bigger if you like aroma.
I concur with the process of racking and then dry hopping as being a bit better having done it both ways as well. You get a bit more aroma more dependably.
BUT - I frequently dry hop in the primary anyway because lazy!
Also no or less risk of oxidation during racking which I've done and which has ruined a few beers for me.
You don't want any air leaks in the racking cane / hose interface and you don't want splashing. Purge the receiving vessel - carboy or keg or whatever with CO2 if you can. I like to use 2 canes. I use the ubiquitous siphon racking cane in the primary and use a straight acrylic cane in the receiving vessel so I don't have to fight with the hose curling and falling out of the vessel. I purge with CO2 usually.
My most recent IPA was 1.065 OG pitched S05 yeast, fermented in the mid 60's and I waited 10 days for the primary to be visibly complete before putting 5oz of hops in the carboy. Cascade was not one of them but I like those ( doesn't everyone? ) I like all the krausen to be sunk and most of the dusty yeast to settle before throwing the dry hops in there. No airlock activity should be observed as others have stated.
I also feel if it takes 10 to 12 days whatever for the beer to clear to a certain point, that's how long I'll wait to dry hop. I usually go 7 days at the most out of convenience as I like to brew and rack on weekends. I've found little difference between 4 and 7 days dry hop effect save for better settling of the hops when they sit longer but I don't rush things. Beer needs time and the beer is ready on it's own terms.
I don't recommend letting them sit longer than 14 days and the one time I did that, I did not care for the results.
I would imagine you have 2 carboys and the batch is split. You doubled the recipe so you should double ( at least! ) the dry hops and put 2oz in each. I would try 4oz in one, and 2oz in the other and see if you can tell the difference.
