I've been all-grain brewing for some years and have been trying to achieve what WilliamsWarn has set up with the BrewKeg system at a great cost and many trials and errors.
So when the BrewKeg50 came out, I got one. It's very good and incorporates everything I've been trying to achieve for years in regards to quick, clean fermentation and carbonation and it saves a lot of money on CO2 also. Recommended.
I’ve been mostly doing all-grain in it and bought a Grainfather (another good piece of Kiwi equipment) and haven't looked back. Sometimes I do a WilliamsWarn 50L ingredient kit to top up the volume I need for unexpected visitors. The WW Premium Lager with some Pacifica hops (off their online recipe) is an easy drinker for most people so a good one to brew.
