6Instantly acquire all the knowledge you need to prosper in the frothy world of beer appreciation. Never again confuse your grist with your gruit, your wort with your yeast, or your butt with your firkin (108 gallons versus nine gallons, since you ask). Bask in the admiration of your fellow drinkers as you pronounce confidently on the provenance of whatever is in your stein (or mouth), and hold your own against self-professed beer aficionados.
