ATF Kvazy (NEIPA) - Grainfather

ATF Kvazy is a Kveik Hazy thats a little bit crazy.

Utilising the phenomenal Voss Kveik, ATF Kvazy can be ready to drink in just 7 days, but it will be at its best after another week or two of cold conditioning.

Dry hopped with 330g of hops, the ATF Kvazy is bursting with tropical fruit with an underlying citrus character and a full juicy mouthfeel.

The ATF Kvazy is bound to become a favourite.

Yeast is not included in the kit. We recommend Lallemand Voss Kveik or Mangrove Jack's Voss Kveik.

Selecting the yeast from the dropdown box above will add one packet to your cart. Please click the + symbol beside the amount to increase this to the recommended quantity for the batch size.

Please Note: Kettle finings are not provided with this kit as beer clarity is not required for this style of beer.

Fermentation Temperature

Voss Kveik is an exceptional yeast capable of delivering excellent beer at very high fermentation temperatures. 

Lallemand Voss Kveik has a recommended fermentation temperature range of 25℃ - 40℃ with an optimal temperature range of 35℃ - 40℃.

Mangrove Jack's Voss Kveik has a recommended fermentation temperature range of 20℃ - 40℃ with an optimal temperature range of 30℃ - 40℃.

When fermenting between 35℃ - 40℃ fermentation can be complete in just 24 - 72 hours with the beer being drinkable straight away, however it will be at its best after one to two weeks of conditioning (preferably cold conditioning).

We recommend fermenting the ATF Kvazy at 39℃ for 3 days before cooling the beer to 14℃ before dry hopping. When cooling the beer care should be taken to avoid oxidising the beer. Please refer to the ATF Dry Hopping Techniques and How to minimise Oxidation article for some options.
