A Stovetop Brewer’s Dream Upgrade
As someone moving from small-batch stovetop brewing, the Grainfather G40 has been a game-changer. The system handles mashing, boiling, and chilling with a consistency I could never achieve on a stove, while the app makes recipe management and monitoring effortless. I could pop in and out of the house at various times and still track progress remotely. This is randomly specific, but when the power in our street temporarily died, I was able to pick up exactly where I left off without any issues.
I had a few initial setup hiccups connecting the G40 controller to the iPhone app, but support was responsive and proactive, and the app has since been fixed. It’s rare to find a company so proactive about improving both their product and user experience!
Cleaning is surprisingly easy, and the automation frees up time to focus on experimenting and enjoying the brewing process.
I feel like I have a personal brewery at home 🍻

Good item & good service
Service is good. Item came fast considering the number of places I had to source in order to get it shipped to my country and item works well and well package. Will recommend to more people to get from this place . Staff was also very prompt in getting back to me when questions were asked.

Perfect for me
Having owned a G30 & brewzilla, I find this suits me better than both units. It has the ability to brew 23L no sparge (no hassle of heating additional sparge water), & allows me to brew 23L high gravity beers with a longer boil time. Great build quality. Wifi is much better than Bluetooth. The grain basket is less hassle than the G30, & allows a faster recirc than the BZ. The recirc hose is simpler & neater than an arm. Sight glass is very handy. The only downsides I’ve found are running the heat exchange from the port inside the kettle, & no tap. Both can be solved by the GF tap add on.
