Abstract
The effect of beer glass surface quality and CO2 content in beer on foam decay was investigated using our experimental method. The effect of beer glass surface quality on foam decay was experimentally investigated for: i) cold & clean glass surface, ii) warm & clean glass surface, iii) cold & greasy glass surface, and iv) cold & dusty glass surface. The fastest foam decay was observed for greasy glass surface. It was found that increasing CO2 content in beer: i) the liquid content in the foam decreases, and ii) the foam breaks down faster. The foam decay and growth kinetics of foam-liquid interface were statistically treated using own models.
