Have you heard of Brussels lace?
Hopefully this empty glass looks familiar to you, if not you may have been drinking some not so great beer or out of a dirty glass.
The following definition comes from realbeer.com:
Brussels lace: The latticework of foam from the head of the beer that is left on the glass after a drink of beer has been taken. Reflects both the care taken in brewing the beer and the cleanliness of the glass from which it is being served.
This picture was taken at The Pub in Lexington Kentucky. It’s an awesome example of what your glass should look like when you’re finished with your brew! This customer was drinking some great beer in a properly cleaned glass.
Can you count how many drinks it took to finish this beer? We count nine.
