Dry Stout The "Irish-style" stout is typically a low-gravity stout with bitterness ranging between 30-45 IBUs. Roastiness is present, but restrained, and there should not be hops in either the flavour or aroma. A little bit of acidity can be present. Often, this type of stout is serving via nitrogen, with all the effects that has on a beer - low carbonation, extra-thick head, lifeless palate and muted flavour and aroma.
