Whether a pure brandy snifter or a variant, these are used most commonly for barley wines, eisbocks and imperial stouts. They are stemmed and footed, bulbous at the bottom and narrowing all the way to the top. Because barley wines often have little head formation, the narrow mouth is fine as far as that goes, but still inhibits aroma a little bit, the tradeoff being the appearance of elegance. Many snifter variants made for beers have wider-than-average mouths for this reason.
