For the initial mashing stage, you
load the Grainfather with crushed grist (up to 18 pounds) per your
recipe, set the thermostat to your desired mash temperature, add water,
and let it go. Because it is a RIMS system, you can easily do multiple
temperature rest mashing if desired - just adjust the
temperature upwards with the thermostat whenever you want to
go to another temperature rest. In addition the manual thermostat
control, the Grainfather Connect Bluetooth control is also included.
After the mash cycle is done, you lift the grain basket partially so you can manually sparge by pouring water over the grain basket into the Grainfather below. You need to heat your own mash water, either by heating 5 gallons or so to boiling with the Grainfather before mashing and storing it in a stainless boiling pot, or heating when it is time to sparge with a separate brew pot on a stove. What we did was heat our sparge water in the Grainfather by getting it to boil in the Grainfather, then transferrring to a stainless boiling pot, and putting a lid on the pot. We then heated the pot briefly on a stove to raise it from 160° F. to the 168° F. needed for sparging,
After manual sparging, the grain basket is removed and you set the 1600 watt electric element to boil. It takes about 60-80 minutes to come to boil depending on ambient temperature. Hops are added manually during the boil per your recipe plan.
When the boil is over, you insert the included counter flow wort chiller to chill the wort which requires an external supply of cold water to run. Our tests found this counter flow chiller extremely efficient, we chilled a 5 gallon batch of Double IPA to pitching temperature (about 78° F.) in 25 minutes, and only used 20 gallons of 70° F. water. It was so efficient that we just ran the end of the wort pipe from the counterflow directly into our fermenter.
After brewing, you run about 3 gallons of
water (ideally saved from the chill) through the GrainFather again
with a bit of PBW or other cleaner to clean the pump, lines, and
counter flow chiller.
The Grainfather comes with a 3 year warranty. We also offer a 60 day money back guarantee on everything we sell, even if you have used it (although this does not cover return shipping). It is 27" tall with the recirculation tube attached, the cylinder body is 12" in diameter, and 15" in overall diameter when you consider the pump and thermostat.
A Grainfather app which allows you to upload
recipes, and times your brew, is available free for Android and
iOS. For iOS, go to iTunes and search for Grainfather, for Android, go
to Google Play (the Android App has just been updated!). The included
Connect Controller includes Bluetooth connectivity.

We highly recommend you read the excellent Grainfather instruction manual before ordering.
Keep in mind the instructions have a mistake - it takes at least an hour to come to a boil with the 110 volt heat element, not 20 minutes like the instructions say (the instructions are based on the 220 volt current of the New Zealand market, not the 110 volt current of the North American market If you want a 220 volt Grainfather G30, order our item J21 instead).
