My first brew on the new Grainfather is the Hombrew Company's American Pale Ale kit that I got free with the Grainfather.
The Grainfather was a piece of cake to use, everything went fairly smoothly for a 1st attempt, and the Connect control box is awesome, taking you through the process step by step. It was a nice day so I set up in the garden to keep out of everyone's way.
The whole brew from unpacking to clean up took me about 6 hours. Does that sound about right for a brew (1 hour mash and 1 hour boil)?. I think I can shave a little time off when I am more familiar with the process, but probably not too much.
It wasn't all hands on of course. I got out for an hour long dog walk during the mash and kept an eye on the mash countdown time on my phone.
I ended up way short on volume and way overshot predicted OG. I added 3L tap water to the FV to get to 23L, but even then the SG was 6 points over expected. The GF mash efficiency calculator said a mash efficiency of 97%.
I used the water volumes calculated by the GF app. I have read that these are normally very accurate, but I think I may have taken too long with the sparge. I don't have an easy way to heat the sparge water and was faffing about boiling kettles and pans and getting enough water to the correct temperature as I was sparging. The Connect app sets the GF to 98C when you start the sparge, so that it is near boiling when you finish the sparge, saving time. I think with all my faffing during sparging the wort might have been sitting at 98C for quite a long time and I will have lost more volume than expected to evaporation.
I may have lost some volume in the transfer to the FV as well. I only read afterwards that you can get a bit more out by tilting and not giving up when the flow reduces to a trickle, as the last little bit can take a while to filter through the hops.
Is there a way to get the last bit of wort out of the counter flow cooler?
So, for next time I am going to keep a close eye on the water volumes, try and speed up my sparge (I have borrowed a tea urn to heat the sparge water), and try and get the last dregs out of the GF by tilting.
I have ended up with a 6.2% brew rather than 5.2%. A higher than expected ABV is not a terrible problem to have, of course. But should I just keep an eye on this, and if I continue to get high efficiency maybe reduce the amount of grain?
