Mangrove Jack’s Craft series pouches are designed for the home brewer who wants more than just a basic beer kit. Mangrove Jack’s Craft Series offer a broad range of craft recipe beer to suit popular beer styles. Each pouch is cold filled using nitrogen to limit the distortion to the malt's flavour and colour. Craft Series pouches may have two sleeves. One for the malt: the other for the recipe hops needed to make your craft brew. Craft Series recipes often use a unique yeast. Mangrove Jack’s Craft series pouches are made In England and distributed world wide.
