"This special porter is made for winter — rich and warming, the way they like it in the North Pole. It was inspired by this famous line from a well-loved children’s story book: 'And Santa sat on his great butt, drinking a hearty brew.' In case you find that amusing, we hasten to point out that in England ‘butt’ refers to a certain barrel used in brewing — a very large barrel, in fact, holding 108 imperial gallons. Back in the day it was quite a normal thing for a brewery to put its beer up in a large butt for storage. Still snickering, eh? Get your mind out of the gutter or Santa will skip your house entirely this year."
