Late hop addition - how much?

[bassetbeer]

Been listening to the show and want to try Jamil's suggestion to add all the hops late in the boil. There was a comment that, because it's late and the extraction isn't particularly fast "you have to add more."

My question is: how much more?

If I have X oz's of hops of Y alpha acid for a recipe with a standard hop addition (say, early in the boil), if I move the hop addition to, say, the last 10 minutes, do I add 2X oz's? 3 or 4X?

Is there a tool or rule of thumb that gives some guidance on that? Or the extraction efficiency of or bittering-minutes for hops?

I'm not big on calc's so I use Promash to figure all that out for me. I understand Beersmith does the same thing. Try one of thier demo versions. It's a lot easier than sitting around running calcs. IMHO.

ProMash is the easiest way to do it. $24.95 and you never have to do math again.

Or you can do it manually. Ray Daniel's "Designing Great Beers" has the calcs you need.

Looking at my spreadsheet, here's the formula:

[Oz of hop X Utilization % X AA% X 7,489] /
[Vol of finished beer X (1 + ((OG - 1.050) / 0.2))]

Here are the Utilization %

Boil Time-----------Whole-Hop----------Pellet-Hop
(Minutes)-----------Utilization %---------Utilization %
Dry Hop - -
0 to 9 -----------------0.05------------------0.06
10 to 19---------------0.12------------------0.15
20 to 29---------------0.15------------------0.19
30 to 44---------------0.19------------------0.24
45 to 59---------------0.22------------------0.27
60 to 74---------------0.24------------------0.30
75 or longer-----------0.27------------------0.34

or.


if you have 1 oz of 6%aau - you'd get 6 aau's for 1 hr of boil
1 oz of 6%aau = 1 aau's for 10 min of boil


in theory

Well, fwiw, as a contrarian brewer I don't usually follow the dictum of the usual and customary practices of most brewers. Maybe I'm just a manky old git, but I've been playing around with FWH for some time now, and have come to some interesting conclusions. Firstly, first wort hopping (FWH) tends to give a finer quality bitterness. Second, FWH lends more hop character to the finished beer than does late(r) kettle additions. Third, FWH seems to have longer lastings effects than what you will find in late kettle additions. Finally, hop character seems to stay with FWH beers far longer than with late addition beers IMHO. As with all things, YMMV, but I strongly encourage you to at least try FWH with your next brew instead of using late kettle additions. I would recommned using at least 25% of your flavor hops, and/or 33-50% of your aroma hops as FWH, rather than using ANY late hop additions to your kettle, and see what differences that makes to your beer. Ttyal, and ilbcnu!

Prost!

I keep seeing you post this information, but all the beers I've tasted that have tried the two techniques just don't support what you're saying. Have you tried this side by side? I have and the results with FWH are very poor in my experience.

Well, Jamil, like I've said before, YMMV. As for your results, I really can't speak for them, as they run contrary to my own personal experience. And yes, I've tried them sXs, plus I've also done a test cross, so that eliminates any possibility of cross contamination of the results. All I can think of is that either you didn't use enough hops for FWH, or you used less than aroma quality hops for your experiments. Using fine quality aroma hops with a charge of about 1-2 ounces for a 10 gallon brew length and having the hot wort drain on top of them where they are mixed in thoroughly wetting the hops in the process. Also, you really need to sparge for 90-120 minutes, which allows for the hops to steep properly so that FWH can work as intended. I think most people fail to get the results I get due to not following the same procedures I use for traditional FWH techniques. As with all things, it's in the details. Ttyal, and ilbcnu!

Prost!
