I have a NB extra pale ale extract kit and i have a left over once of chinook (from a previous batch) and want to FWH with that...How do I FWH with an extract batch?
I did this recently with an extract brew. Basically what I did was throw in the hops after pulling out the steeping grains. It's still not done yet, so I can't tell you how it came out compared to a FWH all-grain batch.
I have done this on a couple of extract brews. I cannot really differentiate the results from FWH on the AG versions of the same beer that I did. It is functionally equivalent IMO.
I recently did this by stepping grains then adding ~2 lbs. DME and then the hops. Then bring to a boil, which gives the hops some time to steep a little before the boil. Haven't tried this batch yet, but kegging it today.
I just brewed that same kit. I similarly added an extra ounce of Northern Brewer hops for my first addition bittering hop and pushed forward the kit supplied 3 oz of Cascade for flavor and aroma. I specifically bought two of these kits to experiment with hop additions trying to make a nice hop forward APA. I added the NB bittering hops at the beginning of the boil just after my first half of the extract addition. It's currently in the carboy ready to bottle so I can't comment too much on the results.
I've never tried adding hops in the time between 170 and boil. What are you trying to achieve by adding before boil? Some extra isomerization of the AA for additonal bittering? What's the taste difference between this FWH and just a longer boil. I'm curious on this method. It seems to me using Chinook vs. the Cascade would already kick the IBU up quite a bit.
EDIT: I just noticed this was a grave dig from a year and a half ago so probably not talking with the OP. I would still be curious from others who have tried this and the reasons behind it.
FWH is done to achieve a "more mellow" bitterness despite the technically higher IBU it imparts. The mechanism isn't 100% clear, but apparently the tongue can tell.
I have tried it a couple times, and was happy with the result but never brewed two batches simultaneously and only gave one FWH.
