I am soaking pepper in vodka to make a pepper extract to put in a beer. Should I just add drops of the tincture in my beer or should I evaporate the alcohol in the tincture first and just add drops of the essential pepper oils left behind?
Drops of the tincture in the beer. IMO the best way is to pour a measured amount of beer ( pint, quart, etc.) and add drops slowly, stirring, tasting until you hit the threshold you want. Then it’s simple math to scale up to your batch size with the right amount of drops. It’s the best way I know - anything else is just trial and error.
