Grainfather G30v3 – 30L All-In-One Brewing System with Counterflow Chiller
This product is shipped directly from our partner Brouwland.
The Grainfather G30v3 is the third generation of the world's most popular all-in-one electric brewing system — a fully self-contained, app-controlled brewing platform that handles every stage of the brew day from mashing through to chilling in a single, precision-engineered vessel. With a 30-litre capacity suited to standard 20–23-litre homebrew batches, integrated recirculation pump, powerful heating element, and the included counterflow chiller, the G30v3 is the complete brewing system for the serious homebrewer who wants consistent, repeatable, professional-quality results without a dedicated multi-vessel brewery setup.
What the G30v3 v3 iteration brings over its predecessors is a refined, matured platform built on years of real-world feedback from one of the largest communities of all-in-one brewers in the world. The recirculating mash system draws wort continuously from the base of the vessel and returns it through the grain bed from above — maintaining an even mash temperature across the full grain bed, improving extract efficiency, and producing consistently clear wort without manual stirring or temperature monitoring. The powerful heating element brings strike water to temperature quickly and holds the mash at any target with precision, while the Grainfather Connect app integration via Bluetooth lets you programme and monitor the full brew day — multi-step mash profiles, boil timers, and hop addition reminders — directly from your phone without standing over the system.
The included counterflow chiller connects to a standard garden hose and rapidly chills boiling wort to pitching temperature in a single pass as it transfers from the system to the fermenter — eliminating the need for an immersion chiller, an ice bath, or a lengthy wait before pitching. Combined with the G30v3's integrated pump, the entire wort transfer and chilling process is clean, closed, and oxygen-minimising — protecting hop aroma, beer freshness, and fermentation health from the moment the boil ends.
Designed to integrate seamlessly with the wider Grainfather ecosystem — conical fermenters, glycol chillers, the RAPT platform, and a full range of compatible accessories — the G30v3 is not just a brewing system but the centrepiece of a scalable, connected home brewery that grows with the brewer.
