I saw a few places selling hop specific IBU injectors. There’s a bunch of different ones. Here is the one for Summit. Anyone ever use them?
“Current AA - 50%
Variety specific hop extract - Summit.
Can be used late in the boil or whirlpool to get variety specific flavors and aromas.”
I picked up Summit, Citra, Chinook, Cascade and El Dorado injectors recently. I will be putting them through some hop trials in the near future. Hopefully they perform better than my non-varietal HopShot trial, which was relatively bland and flavorless.
If it is anything like the CO2 “hot shot” extracts, I’m curious to know how well it will dissolve into the beer. I think it will be like pouring molasses into water. Maybe consider using a bit of high proof alcohol as a solvent.
I’ve been wondering about this as well and thinking that something like the below might work if it was inline in your transfer tubing. I believe they accept syringes with luer lock tips.
This is similar to what I’m planning. I plan to have a flare nut on one end of a small section of tubing, and a female luer-lock connection on the other side. The nut can attach to either a gas post or a liquid post, and the luer-lock will accept a syringe. This way I can dose my keg with finings, coffee, spice tinctures, hop extract, etc. without having to open the lid. I’m thinking that I’ll probably use the liquid post most of the time, because I can back flush with some beer to be sure all of my additives get mixed in properly.
Somebody posted a simple work around to opening the lid a few months back and I’ve been using it since (embarrassed that I didn’t think of it, though) - venting the keg and applying ~ 2psi to keep a positive CO2 pressure, then removing the PRV and injecting gelatin (or whatever) through the hole. I do like the inline idea as a long term solution, though.
