First things first ~ I made a mess of hitting my strike temp, simply heating the water to 67 C, rather than calculating how much over this it needed to be to give a mash temp of 67 C. That meant I had to calculate and add some boiling water to the mash, which I did, but this didn't quite work, so I had to add a bit more,

After the 90 min mash, I drained the mash tun, and forgot to lauter my wort, which I might get away with as its a dark beer. Then the remaining hot water was added ( I remembered to calculate this time) for the 72 C sparge. The tun was lautered / drained and I ended up with just over 23L of wort to transfer into the boiler. 

The boil went well, as did chilling the wort. However, as I was draining the final part of the cooled wort into the FV a drip of water fell into it from the garage door that was open above the boiler, so I didn't risk transferring any more. So I only ended up with 15L in the FV. However, when I cam to clean up I doubt there was the expected further 5L in there ~ so I need to revisit both measuring the dead space in my boiler, and it's boil off rate and update my equipment profile in Brewers Friend.


The result was wort with an OG of 1040, which is higher that expected ~ the hydrometer in the picture reads 2 points high ~ and  if it ferments down to 1007 will give an ABV of about 4.3%. The sample tasted really good; much better than any kit / modified kit I have ever brewed.

Yeast added, its sat in my fermentation fridge at 20C. I've got high hopes for this one.
