there is no beer i've ever had, type or even individual pint/can where i thought "OH GOOD ITS NITRO". but i would grudgingly get guinness on nitro when in a place that had nothing better, or i was desperate for variation from pale lager.
it mutes aroma
the body is simply different, and frankly not superior in any way to appropriate carbonation. many british beers in cans get appropriate lower carbonation with co2,
it comes as a stupid 440ml in a 500ml can
IT EXPLODES EVERY SINGLE TIME
just had an o'haras stout sitting at cold temp for 12 hours and it literally exploded all over my arms and table.
THERES NO NEED FOR NITRO AT ALL.
