There are certain things I really appreciate when it comes to drinking beer at my favorite local watering holes. In addition to the beer’s quality (a given), I relish a beer served in a clean, appropriate glass.
How do I know my glass is really clean, you ask? Well, several things. First of all, “beer clean” is actually an industry term used for a glass that has been cleaned in a very specific way. There are certain techniques and cleansers that must be used. The Brewer’s Association’s Draught Quality Manual goes into great detail on this subject (see page 46). If manually washing glasses, better beer bars should have a three tub sink, if not, they should use an automatic machine with the appropriate cleanser at the right temperatures. I won’t bore you with every detail, BUT the good news is, there are ways to tell if your glass is really clean.
