Hop Oil



What is it? how its made? how to use it? and most importantly how the fuck do you take a clear picture of a bottle so small?

I picked up a small dropper of this stuff at Steinbarts a few weeks ago and it's taken me a while to get a good handle on it. The only information the bottle gives is that it adds aroma and flavor without bitterness and to use it at a dose of 1 drop per 12 oz finished beer. hmmm not alot to go off of. The most info homebrew shop guy could offer up is that its fun to put in peoples budweisers at parties, not being a huge fan of secretly dosing peoples beers with mysterious chemicals at parties I thought i might try it out in some commercial beers as well as homebrews.

All in all I think this stuff is great.
Whatever the stuff is that Steinbarts is selling its 100% Centennial based.
At first I didn't care for the extract because I felt it had a twang. Now that Ive been using it for a while i realize that the twang is really just the total purity of this stuff. It basically tastes like the concentrated yellow lupulin that gather's at the bottom of whole hop packages. whats different about it is that nothing is mellowed from fermentation and therein lays it's weakness. It's awesome but only when used in the presence of many other aroma and dry hops, otherwise the flavor and aroma seem too focused. 1 drop in 12 oz. of an other wise non hoppy beer is going to make said beer taste like you dry hopped it with upwards of 4 oz of centennial. Mix it into an IPA though and this stuff is great. At 5 bucks a batch i think this stuff is a steal.

so what is it?

I'm curious to try thhe hop oil pre fermentation. I'd be willing to bet it's like adding food grade lactic acid. gross post fermentation but not too bad when fermentation has mellowed and rounded its character.
