Clean Beer Glass Check

Question 1

Without beer in the glass, there are

Answer 1

two tests you can perform to

check if a glass is beer clean.

Question 2

Sheeting and spots test

Answer 2

dip the
glass in water and lift out. If the water is evenly coated inside then the glass is beer clean. If the water forms droplets on the inside then the glass has spots of invisible film and is not beer clean. Perfect sheeting = beer clean. Spots = not beer clean.

Question 3

Salt test

Answer 3

first wet the glass, then sprinkle salt throughout the inside of it. Places where salt does NOT adhere are NOT beer clean. Salt will not adhere to greasy film. If salt adheres evenly everywhere then the glass is beer clean; if there is uneven distribution, the glass is poorly cleaned. An even layer of salt adhered to the inside of glass = beer clean.

Question 4

With beer in the glass

Answer 4

you can tell the glass is beer clean if there aren’t any bubbles on the inside of the glass when it is full, the beer forms a proper head, and the beer creates residual lacing on the sides of the glass as it is consumed.

Question 5

Bubbles

Answer 5

Any area where tiny bubbles form is a dirty surface to which liquid cannot adhere. The glass is not beer clean.

Question 6

Head size, shape, and retention

Answer 6

A beer clean glass will allow for a proper head to form and be retained. Greasy film in the glass will rapidly collapse the head.

Question 7

Lacing as beer is consumed

Answer 7

If the glass is beer clean rings of foam will form on the glass after sips. If the lacing pattern is random or there is no lacing, the glass isn’t beer clean.
