Sometimes it’s not about about questions being answered but exploring recipes, tricks ,brew tips and general information about the AF6.5
Yes. My tips/tricks are irrelevant to a 10.5 model, the malt pipe alone will handle most grain+full-immersion combos for a Corny/19L/~5gal batch.
Another I learned by accident: If for whatever reason you need to do a fermenter top-off to meet your volume, Brewfather (and likely most other brewing tools) split out the "post-boil" and "OG" to account for the top off. Discovered this on the first few extract batches.
Armed with this information I have held back a 2L bottle of RO water stashed in the freezer during the brew day to enable:
1. faster cooling - dump the 2L 10C-ish degree water at flameout for a quick chill, as you are starting your chiller (twice during summer)
2. to cover any excess boil-off (I run at 240V, 75%) to make my 21L fermenter volume (only once)
Why consider this? Because each grain bill is different, but the AF 6.5 has (realistic) 23L max wort in the kettle. Sometimes you want a more vigorous boil, so max volume would be slightly less. Your two options are to either make a smaller batch, or get creative
I am certain many folks have read my 6.5 + cooler posts over the months and wondered why I try so hard with a smaller kettle. The 2.5 and 3 gallon batches, with or without MIAB, are fairly pedestrian on the 6.5, as that's what it is made for.
It only gets interesting when you attempt to push the envelope!
