After leaving the brewery and before tapping, the minipin/polypin should last (if kept cool) for about two weeks.Once opened, the beer should pour in good condition for approx’ 5 - 10 days but, in reality, it could well be perfectly drinkable for longer.Note – the last pint might be a bit cloudy especially if you have to tilt the box to serve as this will disturb the sediment at the bottom.
