Пиво Bluestocking - Wheaty Brewing Corps

Blue, floral and Bookish. Brew like a girl. In the spirit of experimentation, we planned to brew a beer the same colour as this year’s IWCBD logo: royal blue. Easier said than done, given the scarcity of naturally blue foods – and that the pigment that makes most of these foods blue, Anthocyanins, is pH sensitive – presenting as blue/purple in environments above pH 4 and red/pink in those below. Enter the Thai Butterfly Pea Flower (Clitoria ternetea); beautiful, edible and intensely blue. We knocked out through dried Pea Flowers in the Hopback and added Pea Flower tea to the fermentor. The result: an indigo/purple/blueish coloured beer that changed every day with shifts in pH. Whatever colour Bluestocking ends up being, a squeeze of citrus should make her pink(er). Not that we advocate that sort of behaviour...
