The "After the brew weekend" post...
So, I think what I actually achieved over the weekend was pretty good. The end result was nearly a full bucket of wort bubbling away nicely and you can't really argue with that!! :thumb:
I also reckon that it just goes to show how simple all grain brewing can be. I read a lot of the Back to Basics brewday topics and in truth this was exactly one of those, just bigger and with scales and a big muslin bag! The sum total of the equipment used:
1 massive pot
1 massive hand made grain bag (because the commercial ones are too small)
1 plastic paddle
1 domestic kitchen gas hob
1 set of kitchen scales
1 bowl (to measure hops into)
1 digital thermometer
1 siphon tube (with the little hop stopper mesh bag that came with the Richies Festival London Porter I did recently)
1 FV, lid and airlock
1 balloon whisk
Lesson #1: AG complicated? It's only as complicated as you want to make it.
It all ran pretty smoothly, with the exception of f**king up my mash temperature and having to bring it down again. Not so easy in 35L!!! A couple of jugs of cold lashed in there helped but that pushed my length up and my pre-boil gravity down.
Lesson #2: The temperature showing on your digital thermometer isn't necessarily the average temperature of the entire pot! It was showing 66C, but then I got curious and shifted the probe 77C! Figuring that stirring a BIAB doesn't matter as there is no grain bed to worry about, the average temperature was 75C. Don't just blindly trust the thermometer.
So I ended up with more pre-boil volume than I expected because of having to cool the mash. I decided to extend the boil. I have actually no idea by how long I extended it but I figured that it didn't matter to the early addition hops as they are just there for the bitterness. So instead of 90min hops they were probably more like 120mins. The aroma Fuggles got the ten minutes they were supposed to.
Lesson #3: Take better notes you lazy git! Actually a little unfair, I was trying to do a mountain of things all at once, putting up curtain poles and the like... Next time I'll note times properly, volumes etc. I should have weighed the spent grain to see what absorption there was yadda yadda...
Lesson #4: Don't try to do too much! I would really have liked to have all the data about what was happening and when to look back over for the purposes of process improvement. Dedicating the whole day just to a brew is difficult though with a new house and a family...
Lesson #5: Derived from #3 & #4 - build a much more detailed brewsheet, complete with those data I want to capture.
Lesson #6: More important probably than all the rest. AG is great fun! Much more creative than bunging on a kit, it's not just brewing. Or is it? The realisation I think is that kits is 90% fermenting with the remaining 10% being other process like sanitation, bottling, etc. With AG it feels like there is far more "making" involved, much much more "input" to the process. Fermenting seems like a minor fraction of the whole. "Brewing" is now a whole lot more than fermenting. :thumb:
Other minor lessons:
7a - mashing your own grain makes you appreciate beer more. As my stocks are a bit low after the house move we bought some beers, Ringwood, St Austel, Adnams... Knowing the malt aromas better made those beers far more interesting than I'd ever found them previously.
7b - burnt on wort is a total b*****d to get off the hob. Not even Mr Muscle has managed it
7c - a better method of grain withdrawal is required. That was the reason behind the wort on the hob. Suggestions for a super-simple winching mechanism gratefully received!
7d - as mentioned previously, when you go AG you have to relearn than nonchalant "patience" of chucking it in FV and forgetting about it.
All in all a brilliant experience. Learned loads. Made beer. Almost total success in my book. :
Finally, a massive thank you to you lot for the help and guidance and inspiration to give it a go. :hat:
