One of my favorite stouts, Left Hand's "Nitro Milk Stout," is supposed to be poured "hard" (rapidly dumping the whole bottle in the cup by holding it completely upside down)
Typical pouring was covered in a previous question: How do you pour the perfect beer
In another question Guinness (a 'nitro' beer) was brought up as a special case: Why does Guinness have a special pouring process / bottle, while other stouts do not?
Are all nitros poured differently than carbonated beers?
And are all nitros poured the same (or very similar) way?
(i.e. all carbonated are "soft" poured and all nitros are "hard" poured)
