It seems that alcohol extractions work well for getting useful properties out of plants for health reasons, but for flavors I think it would ruin them. It depends on what you are making. I know the THC in marijuana, which is very closely related to hops, needs to bond to a fat or an alcohol. I am curious if you could use olive oil instead of alcohol. You could use this as a base in a lot of recipes. My old roommate worked as a chef making desserts. She tried to make a beer dessert, with chocolate cover barley and candied hops.
