ATF Cold IPA - Grainfather | Brewzilla | Guten 40L

From $73.90

The ATF Cold IPA is a crisp, clean brew with a firm bitterness and refreshingly dry finish. Hopped with Mosaic, Motueka, and Wai-iti, this beer bursts with bright citrus, tropical fruit, and delicate stone fruit aromatics. A bold fusion of clean lager-like drinkability and West Coast IPA hoppiness, this is the ultimate brew for those who love a refreshing yet hop-forward experience.

Yeast is not included in the kit. If fermenting cold we recommend using Froth Krisp (Assumed Origin: Weinhenstephan), Fermentis SafLager W-34/70, or Lallemand Diamond Lager Yeast.

If fermenting warm we recommend using Fermentis SafLager W-34/70 or Mangrove Jack's Californian Lager Yeast.

Mangrove Jack's Californian Lager Yeast

Mangrove Jack's Californian Lager yeast is a unique lager strain that has the ability to ferment at ale temperatures and still provide a typical lager flavour profile. 

Fermentis SafLager W-34/70

Sensory testing performed by Fermentis on W-34/70 shows that it is a very robust yeast capable of providing a clean neutral flavour profile across a wide range of fermentation temperatures (12℃ - 20℃). Click here to download the Fermentis iPhone app for more information.

To ensure the target water profile and mash pH is achieved, brewing salts are included in each kit. During the purchase process, you can select your water source from a dropdown menu of known water sources. If your specific water source is not listed, you can provide a water analysis report, or simply select "Not Listed/Not Required."

If you are able to supply a water analysis report showing the amount of Calcium, Magnesium, Sodium, Chloride, and Sulphate in your brewing water, as well as the alkalinity (as CaCO3) or bicarbonate level, and pH, we will adjust the recipe and provide the required brewing salts specifically for you. Just select "I will supply a water analysis info" in the dropdown box.

If any of the minerals in your brewing water is above 50ppm, or if the Sodium level is over 25ppm, please contact us so we can assess whether your brewing water can be adjusted to the target profile of the beer you plan to brew.

The target water profile is provided for brewers using another source water so that the correct mineral/acid additions can be calculated to achieve the target water profile and mash pH. Click here to purchase brewing salts and/or lactic acid. If using chlorinated water we recommend using an activated carbon filter such as our Beer & Water Filtering System with our 0.5 Micron Carbon Water Filter or campden tablets to remove chlorine and/or chloramine from your brewing water.

Please do not hesitate to contact us if you have any questions regarding the addition of brewing salts or acid.
