Great products and an organisation that stands by their product, and looks after their customers.

Daral – G40 Owner, Australia

I’ve only ever owned Grainfather brewing equipment, and the after sales service is the reason I only ever will. It’s top notch, and I’ll be returning when I need a new system.

Chris – App User, New Zealand

Nice to know you value suggestions for improvement.

Ian – G70 Owner, New Zealand

We as a brewing team have been really impressed with continuing excellent support throughout our brewing history.

Jim - G30 Owner, Canada

I have been home brewing since 1983. The Grainfather was a great improvement to boiling on the stove. It's a lot less work and a lot more fun.
