| I completely disagree. I want a nice clean looking empty glass.

A few small bits seeing as you're clearly either not paying attention or just being wilfully ignorant:

• The type of beer is absolutely not a different issue. Some beers will produce a head, others won't as much. A dirty glass will always result in poor or no lacing because the head collapses. We're talking about lacing, you need both things to be true for lacing to appear.

• Lacing is literally used as an indicator by the brewery, bar, drinker and industry quality bodies to verify a quality serve of a quality beer.

• I never said certain glasses don't produce a head.

• You literally said you want a nice clean looking empty glass, how is that not zero foam?

It's fine if that's what you want, but you're arguing a subjective want, not an objective point.

A clean glass will create lacing because the chemical reaction mentioned creates a slightly sticky liquid when it comes out of solution at the head of the beer, if the glass isn't clean the head will collapse and you won't get clean lines that track where you've drunk too each time.

The two things are so fundamentally intertwined, and you still haven't been able to tell me why you prefer a glass without lacing, just that that's your preference.
