Not at all unusual, though no one has demonstrated a good reason. To me it's that it's free of sulfites, unfiltered and unpasteurized, and has a little love in every glass . Many homemade beverages have small amounts of yeast (even when decanted carefully). B-complex vitamin deficiency is associated with hangover, and guess what has a big load of them same vitamins? Yep, homebrew with its yeast.
But I still tell people that it's because I have a tiki of Bryggeman (the yeast god) in my brewery, and I baby my yeast shamelessly. Yeast are aggressively filtered and killed after doing their magic in commercial bevs, so Bryggeman is an angry Bryggeman and takes his vengeance. Like I said, it's the love. Can't you taste it?
