 We did the first batch as usual, heating up the water to 67c before dumping in the malt pipe along with our 5KG grain bill of mostly pilsner malt and some wheat. Historically we have been going off of the bult in temperature sensor in the bottom of our brewzilla brewsystem, but one of its flaws is that the sensor is located right above the two heating elements which means that it is going to measure the warmest water in the pot. This works for turning the heater on and off while recirculating using a pump while the brewery has no equipment or ingredients in it, but as soon as you add anything it is no longer going do represent the temperature of the whole vessel. We put the first sensor below the malt pipe right above the false bottom of the brewery, then we put the second one in the middle of grains.

-The result showed us that we were way off our target. It should be said that this method has yielded good beer for nearly 40 batches with this brewsystem, the numbers showed us that while the heating is set to 67c our malt bed takes nearly 30 minutes reaching the target temperature. This results in only 30 minutes of most efficient mashing. Our thought was that if we can become more efficient at extracting sugars out of the malt we can use less ingredient than we do to day, making the beer cheaper.

 After looking at the graph we decided that for the second batch we would try mashing in at a higher temperature. Hopefully that would let us hit the target temperature of 65c faster.

+For the next batch we heated up the strike water to 75c. After adding the malt pipe and the grains we suprisingly ended up just below 65c, almost exacly on our target.

+Now we just had to maintain that temperature, something that we have done before with great success by setting the heaters to 67c and starting to pump.
