Some may remember the posting of Iron Brewer back in April where the secret ingredients were Star Anise, Jaggery, and Peeps. Well three of the resultant beers had zero head, one had a slight head, and one was off the charts with head due to over carbonation. Star Anise certainly does not affect head in beer. Jaggery could, but it is nothing more than salt and sugar so nothing there to cause an issue. That leads me to believe Peeps are the culprit. While it was only one package of Peeps per 5 gallons, perhaps that was enough to impair the head when the carbonation level is low. Note to self, when using Peeps in the recipe know they may impair head formation and retention. 😉
