Not really something I overheard, but yesterday I was at the LHBS getting some stuff for my next brew and saw an elderly gentlemen just casually eating little bits of all the grains they have in stock. He said hi to me and then mentioned that he never brews with a recipe, he just likes to taste what the grains have to offer and then build a beer around that. I thought that was a damn cool approach so I stuck around to see what happened, and I watched him build a beer with about 5lbs of base malt (pilsner), and about 1/2lb of literally every single roasted or dark kilned malt on the rack..... probably about 20 of them. I like his approach, but good lord am I ever happy I don't have to drink that beer.
