Last time around the mash temperatures were a bit high, the efficiency was a bit lower than I expected and the yeast didn't attenuate as well as it should have due to cold temperatures. Together they made the beer lower alcohol that I intended (5.9% abv instead of 7%) and left it a bit sweeter and thicker bodied than I wanted. That said, it was freaking delicious so I was keen to give it another go with some tweaks.
This time I lowered the mash temps which should take care of the residual sweetness and help attenuation. There's rolled rye in the grist which should take care of the body. I also have a proper fermentation chamber and that should give the yeast a hand too. In addition to all this, I finally got the 40l urn I bought back in March up and running so I enlarged the recipe to brew a 20l batch. I was hoping that the size of the urn would help me get better efficiency and reach the 1.070 OG I was shooting for. It didn't work though, I only ended up with 1.062 so I'm going to have to do some more work to get efficiency up.

I love it when a plan comes together...
ReplyDeleteThe Sydney folk caught up at a training conference these past few days - very much looking forward to hanging with you all.
Can't wait, man. I'm enjoying doing a bunch of little things to prepare for it, it heightens the anticipation.
