The Grainfather - Electric All-in-One Home Brewing System

Yesterday I received my first copy of Brew Your Own magazine.  In it I saw an ad for something called The Grainfather.  Currently listed on Kickstarter to obtain crowdfunding for a U.S. launch of the product, The Grainfather (pictured at the left) is an all-in-one system for home brewing.

I read some reviews of the product and found a copy of its instruction manual online.  It looks like it makes all-grain brewing a lot simpler and easier.

In the device, you can mash your grain bill, sparge it, boil the wort, chill it to yeast pitching temperature with the counterflow chiller pictured next to it (looks like a big hose), and pump it into your fermenter.  The only thing not included is the fermenter and a place to hold/heat your sparge water... but if you have an existing brew kettle you can use The Grainfather to boil a batch of sparge water and use the built-in pumps to pump it into a kettle or stainless steel fermenter to cool down to sparge temperature while mashing the grain in The Grainfather.

Brewing with The Grainfather is said to be very simple.  You start by filling The Grainfather with an appropriate amount of water for your recipe, plugging it into a standard 120V wall outlet, switching it on, and setting your mash temperature.  Then you insert the grain filter basket into The Grainfather's kettle.  The Grainfather's built-in electric heating element will raise the temperature of the water to mash temperature.  Slowly add your grain and stir to ensure that it all gets wet.  Then wait as The Grainfather gets your mash to the desired temperature and keeps it there. If your mash requires multiple temperature steps, you can come back to The Grainfather at appropriate time intervals and adjust the mash temperature on the electronic controller.  As The Grainfather mashes, it also recirculates the wort over the grain using its built-in pump, to increase malt extraction efficiency.

When the mash is finished, you lift the grain basket carefully up out of the wort and lock it into place in clips inside the kettle.  Then you sparge the grain using the water you prepared earlier.  When you're finished sparging, you unlock and remove the grain basket and can easily dump the grain.

Next, you set The Grainfather to boiling and boil your wort, adding hops and other ingredients as appropriate.  When the boil is finished, you switch off the heating element, attach the counterflow wort chiller to The Grainfather and a source of cold water, then start the pump.

The Grainfather then pumps the finished wort through the counterflow chiller into your fermenter, where it should be ready (or nearly ready) to pitch yeast into.

At first glance, The Grainfather seems expensive at around $1,000.  But you have to consider for this price that you're getting an 8-gallon brew kettle (often around $200), a 2000W heating element, a grain basket, recirculating pump (around $150 I think), counterflow chiller ($70+), and an electronic temperature controller.  You could probably build something like it yourself, assuming you had the skills and tools, but you wouldn't have the support of a company that's been selling and servicing their products for years (outside the US).

I'm not sure of the legality of this in Ohio, but there is also a distilling attachment made of copper that can be added to The Grainfather to make it possible to distill alcohol in the device.  Before you do something like that, you'll want to check with legal experts to determine whether that's allowed.

Although I have all the equipment necessary to brew 5-gallon batches at home, I'm giving some serious thought to purchasing one of these through the Kickstarter.  It would make the mashing, sparging, and cooling processes much easier and more reliable than what I do today.  

Reviews of the product say that it's not perfect, but it's easy to use and has a pretty high efficiency (75-82% according to reviewers).  They say the wort it produces tends to be very clear.  It doesn't seem to get bogged down with large grain/hops loads, and saves time relative to other methods that don't involve a high-end computer-controlled brewing system (that costs $2500+).

Update August 7, 2015:  I've received the Grainfather and assembled it.  Here are my initial impressions of the product.

Update August 16, 2015:  Here are the results of my initial (non-brewing) test run of the Grainfather, to check for leaks, clean the unit, and determine mash/steep/boil times.

Things I've Learned Brewing with The Grainfather, Part 2

In the last post, I shared an overview of The Grainfather, recommended equipment to use with it, and an overview of the brewing process.  In this installment, I'm going to talk specifically about mashing and sparging. Having brewed over a dozen batches with it, I'm finally becoming very comfortable with the device, the mash process, and how to get what I want out of it. I don't consider myself a "master" of it yet, though.

For those who have never done all-grain brewing, I want to provide a quick overview of the mash process itself.

Mashing - With or Without The Grainfather
The goal of mashing is to turn the starches in the grain into sugars. More specifically, you want to turn the starches into a mix of fermentable and unfermentable sugars that provide the flavor profile associated with the beer you are brewing. A sweeter beer might warrant more unfermentable sugars. A more dry beer will demand few unfermentable sugars.

To a great extent, controlling the amount o…

Brewing with The Grainfather, Part 3 - Cleaning and Overall Thoughts

In Part 1 of this series, I introduced The Grainfather and discussed how to use it for mashing and sparging.  In Part 2, we talked about boiling and chilling the wort with The Grainfather and its included counterflow chiller.  In this final segment, we'll discuss cleanup and overall thoughts about the device and its usage.


Once you've pumped the wort from The Grainfather into your fermenter and pitched your yeast, you're well on your way to a delicious batch of homebrew.  Unfortunately, you've still got some cleanup work to do.

The cleanup process in my experience will take 20-30 minutes.  It involves the following tasks:

Removing and discarding the grain from The Grainfather's grain basketCleaning the grain basket, kettle, recirculation tube, and wort chillerCleaning all the other implements used in brewing (scale, scoops, mash paddle, etc.) At the end of the brewing process, there will be hops bags (if you used them), grain and other residue, and usually so…

Brewing with The Grainfather, Part 1 - Mashing and Sparging

(Important note:  This article series is based on the US version of the product.  Prices are expressed in US dollars, measurements of temperature and volume are in US units unless otherwise noted.)

iMake's The Grainfather is an all-in-one RIMS brewing system designed to be used indoors with household electric current.  It includes the kettle, grain basket, recirculation tube, pump, electronic temperature controller, instruction book, and counterflow chiller.  It does not include a mash paddle, fermenter, cleaning supplies, or pretty much anything else.  The price is around $800-900 depending on where you shop and the discounts offered.

The Grainfather handles mashing, boiling, recirculating, sparging (to a degree), and chilling of the wort.  You'll still need a fermentation vessel of some sort and some other supplies we'll discuss later.
