Stubborn pHool
Iron Furnace Brewing

This version of our sour is made with mango and pineapple. While the pH in the name (pronounced “fool”) gives tribute to the acidity required to brew this beer, there are different opinions as to whom stubborn refers. You be the judge. Lactose and yeast come together to make it sour. If you’ve never had a sour, give it three sips before you decide if you like it.
