FWH

Who here utilizes the First Wort Hop technique? It seems easy enough. How many IBU’s (%) do you typically aim for using this technique as part of your overall hop schedule?

I don’t do it… but I can tell you that for the purposes of IBU calculations, treat it like it’s in the boil the whole time… because it is, and photospectroscopy proves that FWH gives your more IBUs than regular boil additions.  Tasting experiments have been all over the board as to how bitter it actually tastes.  Everyone refers to the old one from like 50 years ago where the FWH resulted in “smoother” bitterness.  However the experiments I’ve read about more recently couldn’t tell much difference between FWH and a regular 60-minute addition.  Which makes perfect sense to me.  If you want to try FWH, consider doing an experiment with two batches in one day using different hopping techniques, and please report back your experience.

I FWH everything.  IIRC, it’s a roughly 10% boost in IBUs calculated compared to the same length of boil.

I used to use it, but now I’ve moved to 60 min + hopstand ± dry hops for pretty much everything. I definitely felt the character of FWH was different than a 60-minute addition, but I never did a side-by-side myself to confirm it.

I use FWH on any style that is hop forward.  Although I’ve never done side by side comparisons, I think it gives a smoother bitterness, with more hop flavor than a regular boil addition.  Even though the measured bitterness may be higher, the perceived bitterness seems lower.

+1.  I did FWH for a long time but I’m liking this method better for most styles. For beers that don’t get much or any late hopping (helles, hefe, etc.) I still use FWH with no whirlpool hopping, though.

I agree. I brew an all FWH kolsch and it has amazing smooth bitterness and great hop flavor. Anecdotal evidence aside, it works well for some beers. Definitely try it and see for yourself.

+1 - one of my favorite beers.

Here are some tips that I learned from Jeff Renner on FWH.

  1. He likes noble or noble hop derivatives for FWH.
  2. He keeps the temp at 170F+/10F
  3. He hold that temp for an hour, so do other things when you can.

I have tried it and like the results in some beers like a Helles or a CAP.

This is something I would agree with, insomuch as it involves boiling noble hops for a full hour or more.  I find that one of the secrets to creating “that German lager flavor” involves having noble hops in the whole boil.  In my experience, noble hops do not behave the same way as other hops, where you might save most of your hopping for the very end of the boil – no – noble hops need a longer boil time to develop their full flavor.  So if you want to try FWH, noble hops are certainly a great option.  Will you get “a smoother bitterness”?  I don’t know.  But at least you might achieve “that German lager flavor”… which you can also get from a normal 60-90 minute boil addition with your nobles.  Don’t always just use a high alpha hop for all your bittering, and don’t always save all your flavor and aroma hops for the very end of the boil; it’s not necessarily always the best way to go for all your beer styles.

That’s pretty interesting. I’ve never heard of holding a fwh temp, especially for that period of time. I may have to give that a shot for a helles.  170F is the temp I like for whirlpool steeps, too.

Similar to mash hops, no?  Although they would continue on to the boil rather than be replaced by new hops.

Mash hops don’t seem to contribute much.  Numbers and presentation from an NHC seminar last year…

Yep.

EDIT -  FWIW, I’m not a proponent of mash hopping. I tried it several times and felt like it was a waste of hops. OTOH mash hopping isn’t typically 170F/60 minutes.

I brewed a CAP yesterday and used Perle as FWH and Gr. Hallertau in the whirlpool at 170F.  Bittered with Clusters for 60 minutes.  I hope it’s as good as the plan.

Mash hops leave a lot behind in the mash. Link to NHC presentation was already posted.

The hour at 170F is similar to the time it takes to sparge out in a production brewery. Some do long whirlpools to replicate what is done in a production brewery. Same logic in play for the longer FWH time.

An added bonus of FWH I’ve found is reduced foaming as wort comes to boil.  It doesn’t take much to do this so I think I’m going to go to at least some FWH for all my beers.

FWH for me has resulted in similar results as full boil hops in both aromatic, flavor, and bitter perception. In other words, not much different that a 60 minute addition on a 60 minute boil. The biggest advantage, for me, is that it’s easy to just toss them in while sparging and not have to wait until you come to your boil.

Mash hops are about the best way to get some hop ibus into a no boil berliner :D. For normal (boiled) beers, I would conclude mash hops are a waste of hops.

I’ve used mash hops once on Janet’s brown and never after. It does smell awesome. Throwing $0.50 worth Columbus or cascade in the mash isn’t going to break the bank.

This is the only time I use them, though some do end up getting boiled by decoction.
