Beer Clean
A term that refers to the cleanliness of a vessel used to drink beer.
Here are some ways to tell if your glass is beer clean:
Hold the glass up to a light to see if there are any fingerprints, smudges, lipstick, etc.
Look for bubbles clinging to the inside of the glass.
Rinse the glass with water before pouring beer into it and look for sheeting from the water, not beading.
Rinse the glass with water and sprinkle the inside of the glass with salt - if the salt sticks to the surface, then the surface is clean.
If you are served a beer in a glass that is not beer clean, send it back!
