Rosey Nosey is 4.9% alcohol by volume but promises a rich and complex character, bolstered by generous English hop flavors. Batemans indicates that it “compliments any turkey” but I think this would make a great accompaniment to a traditional Christmas pudding with brandy sauce.
In fact, why not make a Christmas pudding to accompany your Christmas beer? There are a number of recipes online but wikiHow has a great writeup. The recipe actually calls for 10 fluid ounces of beer—so my suggestion is get two bottles of Rosey Nosey, one for in the pudding and one to go with it.
