Braumeister V Grainfather
Today I was given the chance to run the Grainfather side by side with our Braumeister. JoeD from Imake let me choose the recipe and brew it. I decided on a rye ipa I have done a few times without fault on the Braumeister. I figured the 24% rye and a protein rest would test the thing out hopefully get a stuck mash. 55 degrees for 10, 66 degrees for 45,72 degrees for 20 then a mash out at 76 for 10
So mashed in the Braumeister first not to give it a head start but so I would have time between the 2 when it came time to remove malt pipes and sparge. Note the gentle trickle of the Braumeister.
Mashed in the Grainfather and Joe gave me a rundown on how the controls work and started recirculating at a rate of knots. I thought you beauty this thing will stick for sure.
Changed the mash temp to 66 and started the timer to see how fast the ramps were. 16 minutes to climb 11 degrees so an impressive 1.4 degree a minute. It seemed to handle everything I threw at it thus far. I took it through to the 72 rest and checked the display on the Braumeister, Still had 15 minutes at 66 left, wow this thing is fast we said. Got it to mash out, removed the malt pipe and sparged to get my volume to 28 litres with ease. No stuck sparge, no problems there at all.
The Braumeister was still chugging away slowly just getting to 72 at this point.
Weighed out 2 x 240 grams of hops, had a beer and chatted to Joe about what there plans were for the units and finally the Braumeister was ready to sparge just as the Grainfather was starting to boil.
Had some lunch and more beer waiting to put in our payload of hops at 10 to go.
Finished the boil and checked the gravity 1.059. 1 point off the expected gravity checked volumes and was 2 litres under for the recipe so roughly 75% brew house efficiency. I had worked the recipe at 80%. Ah well close enough we said. Looked at the Braumeister display and still had 50 minutes left on the boil.
We had to use the counter flow chiller to get the wort out and into a cube as all our fermenting fridges are full. So sorry guys no specks on how quick that works.
Results.
We all know the Braumeister is a good bit of kit and what it does it does well but I was astounded at how well the Grainfather stacked up next to it. Quicker ramp times. Bigger malt pipe and the boil was a lot more vigorous were the first things that struck me. The let downs were a slight over and under shoot by a degree on the temps when getting to them and the slightly lower efficiency. Both of these points could easily be fixed both by the brewer and the manufactures.Talking to Joe he said they are already coming up with a PID control unit that will be upgradeable on all models. They seem to think that people need to feel like they are doing something and that was the reason for the control unit they went for.
After spending a few hours on it I would quite happily buy one especially for the price they are going to go for.
