From the brewery:

Something to remind you that sunnier days are on their way - a mango ice cream lolly in beer form. A massive addition of mango puree to a tongue-tinglingly tart base makes a wave of fresh fruit flavour, whilst lactose boosts a thick, smooth body, and delivers unctuous creamy sweetness. Sessionable, juicy, moreish and sour; we'll be drinking this til summer comes.
