I'm doing consecutive batches in my grainfather at the moment. I pumped out the first batch into my birko urn while i was sparging.worked well. Now I'm boiling the first batching and mashing the second.

Turned out to be a fairly long day in the end. I can only chill one brew at a time because i only have the chiller that came with the grain father. Maybe i should try and no chill a batch. I've always liked to have my wort sealed up with yeast added before i go to bed though.Coldspace said:Good idea,
I've got a spare urn, mite try and get 3 double batches out in a day .
I reckon 62% is way too high for a really big 1.100+ high grav brew. Closer to 50%. But I'd be keen to hear what others have experienced with super high gravity brews in the GF.kaiserben said:I dropped the efficiency setting down to 62% and set the batch size to 16L.
Actual OG into the fermenter (was well mixed) ended up being only 1.068. Missed my target by a whopping 34 points.
Volumes shouldn't matter as much as your expected gravity. If you're trying to make say a 5% beer, then getting your pre-boil gravity correct will matter a lot more than if you've got 26.5 litres or 28 litres pre boil.Wadey said:Hi all.
Ive just finished my 3rd brew on the grainfather and I'm finding that I'm not hitting the 28ltr pre boil volumes. I seem to be up to 2ltrs short. Today's brew was only 26.5lts pre boil. My sparges are only taking about 10 minutes and I let the grain drain while the kettle is coming up to a boil.
Any suggestions as to what the issue might be?
Cheers
There does seem to be an emerging theme of fast sparge and lower efficiency being directly related to the grain not being milled finely enough.btrots87 said:Did my first grainfather brew on the weekend, hit all my volumes perfectly but my efficiency was really low, around 58% brewhouse efficiency. Not really sure why, my sparge seemed really quick so maybe it was channeling through the grain bed.
I've got another brew planned for next weekend, I'll see if it improves before I get too concerned. Beer tastes good out of the fermenter so far though.
