Crisp and highly aromatic the ATF Cold Session IPA showcases a vivid blend of hop character supported by a clean, light body and lager crispness.

The aroma is a bright and inviting mix of tropical and citrus notes. You’ll find ripe passionfruit, peach, and pineapple layered with the distinctive zest of grapefruit and tangelo. This fruity bouquet is complemented by a fresh pine character.

On the palate, the flavour mirrors the aromatic promise. Juicy tropical fruit and strong citrus notes of grapefruit and lemon-lime lead the way, supported by a subtle, resinous fruit quality. The experience finishes clean, dry, and refreshingly crisp.

Yeast is not included in the kit. If fermenting cold we recommend using Fermentis SafLager SH-45. The ideal Lager yeast to enhance hop thiol release, crafting beers with enhanced levels of fruitiness and intensified citrus and tropical notes

Alternatively we recommend using Fermentis SafLager W-34/70 or Lallemand Diamond Lager Yeast.

If fermenting warm we still recommend using Fermentis SafLager SH-45.(max 18℃) or:

Fermentis SafLager W-34/70 (18℃), or
Lallemand NovaLager (max 20℃), or
Mangrove Jack's Versa Lager (max 20℃), or
Mangrove Jack's Californian Lager Yeast (max 20℃).

ATF All Grain Brewery Kits

ATF All Brewery Kits – Brew on Any Setup with Precision Water & Grain Ratios

These recipes have been designed to be brewed on any home brewing setup using a water‑to‑grist ratio of 3 litres per kilogram. Every kit contains a detailed recipe and easy‑to‑follow instructions.

Boil‑Off Rates – Pre‑Calculated for Your Batch Size

The pre‑boil kettle volumes are based on the following boil‑off rates:

3.5 litres per hour for 24 litre batches
4 litres per hour for 48 litre batches

Perfect Your Water Profile & Mash pH with Brewing Salts

To help you achieve the target water profile and optimal mash pH, every kit includes brewing salts. During checkout, simply select your water source from a dropdown menu of known profiles.

Your water source not listed? Choose “Not Listed/Not Required”.
Have a water analysis report? Select “I will supply a water analysis info” – we’ll adjust the recipe and provide custom brewing salts for your water.

We need these values from your report: Calcium, Magnesium, Sodium, Chloride, Sulphate, alkalinity (as CaCO₃) or bicarbonate level, and pH.

Important Mineral Thresholds for Home Brewers

If any mineral in your brewing water exceeds 50 ppm, or your Sodium level is above 25 ppm, please contact us. We’ll assess whether your water can be adjusted to the target beer profile.

For Brewers Using Other Water Sources

The target water profile is provided so you can calculate your own mineral or acid additions.

Removing Chlorine & Chloramine

If you’re using chlorinated tap water, we strongly recommend an activated carbon filter (such as our Beer & Water Filtering System with a 0.5 Micron Carbon Water Filter) or Campden tablets to remove chlorine and chloramine.
