We've all heard it, some of us preach it, but is it true? Does the dishwasher ruin head retention in your barware and make for a poor beer drinking experience?
Last week, I was listening to an old Basic Brewing podcast, and the guest (Ray Daniels, I think) was talking about "beer clean" barware. He talked about using salt to determine whether a glass is beer clean or not. This morning, Laughing Gnome posted this video describing the same technique.
I have been cleaning my barware in the dishwasher (WITH Jet Dry) for years knowing full well the possible negative effects. However, I've never perceived any ill effects. Today, I decided to prove that my dishwasher does indeed produce beer clean glasses. This glass came out of the dishwasher a few days ago, shortly after the Jet Dry reservoir had been replenished:
I got the same result with one of my Sam Adams glasses, washed even more recently. So, not only am I not perceiving any ill effects, THERE ARE NONE! I'm not saying that everyone should start using their dishwashers for barware, but in some cases, it might not hurt. Of course, not all dishwashers are the same. Also, we have VERY hard water, and that may make a difference.
Is the dishwasher really my enemy? This test yields a definitive, "NO!"
