Hop Hash

[CorneliusAlphonse]

My aunt picked up some "hop hash" for me from the festival. I wasn't there. Anyone know what it is/what you do with it? Its from "Southan Farms" which is in NB

Talk to LiverDance - he got some as well.
Edit: see Nash's correction below!

Talk to LiverDance - he got some as well. Basically a concentrated packet of lupulin, for late hop addition.

That's incorrect. It's ~ 55% by weight readily available acids, and ~ 20% by weight essential oils. Using it simply for a late aroma addition would yield one.epicly.bitter.beer.

Thanks for the correction! We were guessing when talking about it last night after the 'fest.

Does this mean 1 gram carries those percentages?

Yup, any measure does.

So.... If a hop is listed at 10% A.A.,10% of the total hop weight is actually alpha. Multiply that by utilization factor to determine how many g of alpha acid you actually have, or want in a batch. Calculate that out to get to the amount of hash you need to use for targeted g of A.A. The acids are readily available, basically pre-isomerized, no boil required.

What I didn't mention was that the total weight of acids are alpha and beta. Approximately 30% total weight is alpha. We do perceive bitterness from beta as well so.....

Beersmith uses 100% for hop utilization, does this seem appropriate for the hop hash as well? Also, MOD's can I get this info put in a new thread labeld hop hash?

Beersmith uses 100% for hop utilization

That makes very little sense. None, in fact.

So my 189% mash efficiency probably isn't right either What makes sense to use for utilization on this product?

How do you mean it uses 100%? The max alpha utilization possible on a 90 minute boil with pellets is ~ 35%.

Personally I'm leaving hop hash out of the software all together and using a pencil. But yes, the alpha that's there is 100% available even without a boil. Every gram of hash has ~ 0.3g of AA.

My bad, I was looking under the equipment profile when I seen that (BS show utilization in the kettle at 100% for less than 20 gallons). the real number for the hops in BS is based on which formula you use (rager, tinseth) so you are correct it is a lot lower than 100.

Right, then it becomes less and less as the boil time shortens. But we both know that already Anyways, this is why I'm using a pencil, not sure that software can handle it without strangely messing about the database.

On that note, if you make an IPA on your system and wanted 40 IBUs from a 60 minute hit, how many hops at what AA % would you use?

[LiverDance]

On my system for a 21.8L (1.064) batch I'd use 20g @14%AA to give me 40IBU's

Alright so 20(g) x 0.14(% AA) x 0.30(% utilization) = 0.84g isomerized alpha acid. About 3g hop hash should put you in the ballpark since it's ~ 0.3g AA per gram.

I'd either add it in the whirlpool to retain the oils, or first-wort-hash it You could dry-hop the finished beer if needed.

This is all theoretical, I haven't used any yet but have some. I have no idea what perception we'll have of the beta acids, if any. If it works well it could save a shitload of wort-loss due to hop-sludge in hoppy brews though.

[NASH]

PS: I am going to run a test with it on a firkin of Deadwood Wheat.

My plan is to dry-hash it to the tune of about 40 IBU.

Should give us a pretty good idea of the bittering and aromatic oil capabilities. I haven't done it yet because I'm too low on wheat beer until the new batch comes online Wed, so it'll be the firkin for the following Wed

[LiverDance]

Right on, sounds good. Thanks for the help. I'll mark my calender to go down and try that on the 19th.

Cool, should be interesting to see if it's a tongue-ripper or not

[NASH]

Okay I pulled the analysis sent to me, my rounded figures were a bit exaggerated

37.2% AA or 0.372g alpha acid per gram of hashish

Therefore 2.258g of hashish = 0.84g AA for your 40 IBUs.

Hey, I understand those chromatograms! We need a Science Porn thread for nerds like me.

good, you can explain them to me. I'm still wondering when the butter knives come into play

Another thing to consider with this stuff is that it is pretty much water insoluble, so if you were thinking of "dryhashing" (love it) you might want to consider a solvent extraction using some type of ethanol just before. This is just a suggestion, we haven't had a chance to play with this stuff in a brew yet either, but the chem nerd who did the chromatogram thinks it might help bring some of the oils out.

I considered that but don't think I'll go that route in the firkin. If you can dry-hop, you can dry-hash. It'll dissolve with a little time, same as using whole hops.

...but is it alcohol insoluble? will the alcohol in the beer do the trick?
