Guinness Flavored Marmite for St. Patty's Day

File this under "things you really didn't need to know as a Red Sox fan," but just in case any Guinness lovers with marmitian tendencies ever stop by here, I thought I'd spread the word: In honor of St. Patty's Day, Marmite has released a limited edition version of its spread made from Guinness yeast.

Me? I think I'll keep my Guinness liquid.
