Grainfather GC2 & GF30 Bundle

Grainfather GC2 Glycol Chiller & GF30 Conical Fermenter Bundle

A complete precision fermentation system combining the Grainfather GC2 Glycol Chiller with the GF30 28-litre conical fermenter. Designed for home brewers who want professional-grade temperature control — from active fermentation through to cold crashing — without compromise.

GC2 Glycol Chiller

Controls up to two fermenters simultaneously, each with independent temperature settings and schedules. Capable of reaching temperatures as low as -4°C, making it ideal for lager fermentation and cold crashing. Uses a 2:1 mixture of water and propylene glycol for stable, consistent temperature regulation. Compatible with Grainfather S Series fermenters and other models via the GCA Adapter.

GF30 Conical Fermenter

A 28-litre double-walled stainless steel conical fermenter insulated with polyurethane foam. Features a built-in gentle heating element and integrated cooling sleeve for precise temperature management throughout fermentation. The golden angle conical design optimises yeast and sediment collection, and the dual valve tap allows easy sampling, transferring, and yeast dumping. Monitored and controlled remotely via the Grainfather App.
