I think you may have solved this!
I'll need to measure the next 'hoop' i find to be sure, but I think they could be coming from the holes in the false bottom. I do clean it after each brew, but even after a good scrubbing it's still quite discoloured - sort of tea stained.
I'd always assumed...
Interesting suggestion, but they're not as robust as those look. The hoops i keep finding are incredibly thin and can be ground into peices between your thumb and forefinger.
I brewed on the Friday just gone and found two hoops in the bottom on the BV boiler before I started adding the water...
Yes, I agree and its strange that any bits from the original machining would still be coming put of the coil after it's been used in so many brews since I bought the RB. The mystery remains unsolved...!
Thanks for all the good suggestions. I brewed a beer on Saturday - all new grain from a recent order (but from my regular supplier). I found one more hoop or ring when filling the robobrew with the mash water, but nothing during the clean-up or left in the RB after the clean (which is where l...
Thanks for all the suggestions chaps. I'll open ul the bottom and see if I can see anything obviously wrong. My worry is that if it's the pump, there will be no way of telling without completely dismantling it - and that's beyond my skills.
I do crush my own grain. I have an old Bulldog Malt...
I think the hose gun might be a red herring as I just remembered that i changed the gun to an older hose nozzle before the last brew.
Just checked the hoops with a magnet and they're not magnetic. I don't use the BZ for anything else.
I've only found them at the start of a brew but also not ever checked that hard after the final clear up. the only things stored in the RB between brews are the different brew parts: pump arm, chiller coil, false bottom, hop spider etc. The RB is stored in its original box in my garage. Nothing...
Just starting a brew in my Brewzilla Robo Brew and noticed these tiny metal hoops in the bottom of the kettle. This is the second time I've found these. Last time I noticed some after filling the kettle to heat the mash water. I removed those with a sieve and thought they might have come from...
Question for everyone who transfers hot wort to the FV and pitches the next day when cool: Do you aerate the wort when cool before adding the yeast (or is enough oxygen added in the hot transfer)?
Plum Porter is finally in the bottle! Left it an extra week in the FV hoping to get the gravity down a little further. It dropped an extra couple of points over the final week but still ended quite high at 1012.
Should be alright but I've only primed with 1/4 tsp of sugar in each bottle just...
