Recently decided to splash out on a Grainfather. Got the coat, hop spider, whirlpool paddle and stainless paddle. Just done the first brew.

Not as simple as I thought it would be, but then it was the first run, and the first time I ever brewed indoors. That with the wife cooking around me, and me stopping to eat, which I normally never have time for.

Seemed like my crush was probably a bit too fine (probably 0.8-0.9), as the flow through the grain was pretty slow. But I stirred half way through, and during mashout the wort started to clear. I've increased my roller gap for next time.

I had more wort pre-boil than the litre markings reached, so I could only guess at pre-boil volume and so didn't calculate boil off. The litre markings are not accurate anyway, but I created my own conversion calculator. I measured my loss to trub at 1.6l (that included the trub, so it's less really). That's easily the least I've ever lost, and contributed a lot to the BH efficiency.

Managed 80% BH efficiency. That beats my best ever batch sparge by 6% , and my average by 12%. I aimed for 25l and ended up with about 27l, even though I hit target SG (I'd planned for a 75% BH eff.). So I had to throw away 1 litre of bitter wort; never done that before. I think the main factors contributing to the efficiency include the hop spider, the low position of the tap, and the fly sparge.

Coat: Seems very high quality in comparison to the Braumeister coat and seems to do the job well. Shame you can't take off when chilling.
Hop spider: This is brilliant for leaf hops. I was left with only protein trub. All liquid drained from the hops when I removed after the boil. The 800 micron is perfect for leaf, you get good movement inside. Probably not good for pellet.
Whirlpool paddle: Rubbish; could have done without this. Too many gaps and holes for true cleanliness. Doesn't even fit in the neck of my fermenter. All said, I didn't use for for post-boil whirlpool and did end up with trub in my fermenter, so I'll try it for that next time; let's see.
Stainless paddle: As it is long and rigid, really useful for mash-in and mash stirring. Would be very difficult otherwise.

Sparging took quite some time and is the only time you really need to be engaged for an extended period.

Chilling with the counter flow chiller took about as long as with my immersion chiller, about 45 minutes. After 2 buckets, I switched to my ice water recirc. The advantage then is that I don't need to stand around for 45 minutes waggling the chiller.

I'm a bit disappointed that the controller is loose, so when you tip the unit for cleaning, you have to be really careful. I've found using my chin to hold it in place works ok. And they make a big deal of the cleaning recirc. Well that doesn't really ADD anything, just that it wouldn't be possible to rinse the pump, pipe and chiller without it. You still have to wipe out the boiler.

The app worked flawlessly. I was even surprised when a beep went off to remind me to start my sparge water heater; and I had forgot :hat:.

All in all, pretty impressed. I'm sure when process is settled, I'll gain a lot of free time on brew day. And that was the purpose.

Good efficiency there! I've never thrown away any wort. I usually get close to but not exactly the quantity I'm after.

Had a brew night last night and sparging took quicker than normal, about 15 minutes all in. I usually like to sparge for a bit longer to ensure the grains are rinsed as much as possible. The counter flow chiller works really well but it takes a little bit to get it dialled in. Last night's chilling took about 5 minutes to drop from boiling to 55c, which was a little bit of a problem because we had whirlpool/steeping hop additions and it didn't give them chance to actually do anything.

I just remove the entire controller when I clean it. Unplug the plugs and clean it that way. I only really recirc when cleaning to clean the pump/pipe etc. as you've suggested. The rest of it, I just clean as I would any brew kettle.

Sounds like a pretty good brew day/night then! Well done!
 
Welcome to the club. My first brew with it took the best part of 10 hours (including having to pick the wife up from work just before the boil, so I had to switch it off, to then switch it back on again)

Can usually get a brew done, cleaned and packed away again in about 6 or so hours now, assuming I've set it all up the night before and the water is up to temperature when I get up in the morning. There's now a lot more "autopilot" when brewing than there was at the start.

My efficiencies are now usually in the high 80's, which now I've got that dialled into my recipes, I hit my numbers.
 
Cheers guys. While reviewing my brew day, I realised a big boo boo. I needed total liquor of 34.4l, so had filled my Buffalo HLT to full mark at 36l, with the intent to remove 1.6l. But I have no memory of that removal :doh:. That would go a long way to explain why I overshot my target brew length. So with the loss to trub tweaked, the calculations make more sense now.

So I'm expecting a hit on my efficiency with the increased crush gap I've now set, and with less sparge water. I decided to plan for 77% for my next brew. The sparge will probably move a lot quicker too.

This time I tilted the Grainfather to catch all wort, but I guess that would be one reason I pulled in more trub. Next time I'll whirpool and I'll keep my eye on this to find best practice.

Brewday took 6 hours too, but already, with this first ever run, I was just standing watching and taking time to do other stuff. So I can already see, even if start to finish is roughly the same, there will be a lot less goings on inbetween.
 
My first 3 brews were mostly learning and dealing with new hassles that didn't exist in my 8L stovetop batches. Now I've done close to 20 batches and I wonder what to do with myself once the mash/boil is going. :-)
 
Don’t want to hijack your thread Fore. Just one quick question. Would you say the hop spider is essential from the off? I’ve got one coming (hopefully tomorrow).
To get the missus to agree I virtually told her it would do all the housework, the lot.
Don’t fancy telling her I need to shell out another £40.00 for a spider.

The hop spider is a fairly contentious issue with users online, some swear by it others see it as unnecessary, a faff to clean and affects you utilisation. I've not used one, had a few filter clogging issues but been fine since I've started whirlpooling better and leaving it a good 15 mins to settle. I was considering getting the spider but as I mostly brew 15L batches it wouldn't reach deep enough into the kettle for good contact which would mean suspending it somehow and probably knocking it off.

Thanks for that Zephyr. It’s not an absolute must then.
 
I had a hop spider for one brew. I'm in the "faff to clean and affects hop utilisation" camp. It was both those things.
Nice one. Thanks for the confirmation. Just have to get my whirlpooling technique in order. Not something I’ve ever done.

Hi. Definitely not absolutely necessary, but having had the hops sitting in the bottom of my boiler for years, I loved just dragging them out at the end and having all the hop infused wort run out. Wasn't difficult to clean with a potato scrubber and well aimed water spout. In any case, doesn't need to be spotless; it's used in the boil.

I think I've previously [suffered] over utilisation with a vigorous boil; always found my beers on the bitter side. Of course I could have adjusted IBU's down, which I was just on the cusp of trying, but now I'll just stick with what I had assuming I'll lose a bit of utilisation. But with 800 micron and periodic stirring, I can't imagine I'll lose lots. All the liquid supported by the hops runs out, and all the hop goodness with it. Oh, and I put the irish moss in there too, but not sure how much of that passed through; none as far as I could tell.

As long as I can get away without one for now, I could get one later when the sting of the £650.00 has passed.

I use a SS paint stirrer attached to a drill for my whirlpool, give it a quick 5 min spin, leave for 10 mins and you're good to go. The extra 10 mins can effect the IBU's, but I just reduce the first additions a fraction to compensate (nothing scientific there!)

Thanks Norfolk. I will have a look out for one. Just putting the unit together now. Pretty excited.
