You should have mentioned sandblasted glaseses, they give the pint an excellent head. They also make it far easier to drink

What beer style do you think has the best looking head?

[@shadowrayz]

Stouts, for me!

[@DaftCatBrewing]

Same here, whether it is the silky and creamy smooth tight foam of a nitro poured Guinness, or the thick brown head on a thick imperial stout, both of them have me admiring the look of the beer and licking my lips with the foam. Cheers for sharing

[@BeerByTheNumbers]

How to increase foam in beer

[@DrHansBrewery]

Who dosen't Love a good head!

[@ElBosquee]

Sour beers tend to have poor head retention

[@bdee1084]

Smell and touch*

[@kenhoward3512]

"...but there have been conflicting studies in the past." Obviously, this will require further research.

[@kerl6859]

To answer the question, foam is beer. Let it sit and it will become a liquid (beer).

[@OldNorsebrewery]

Ohh, that's stout. Wheat aldo have a good head

[@BeerByTheNumbers]

I do like those lacy wheat beers. cheers!

[@Bottomsupbeer1]

We like to pour ours from the bottom! Check it out!
