I assume then that suspended particles affect hydrometer same as my refractometer, because when I cross check with hydrometer reading is the same?

@hotbeer No I'm just measuring the wort sample, post mash, post sparge, post boil and after filling fermenter. No late sugar additions. Mixing wine kits with water is a challenge to get an effective mix. But I'm seeing this issue with all grain brews.

That's my question really, I need to mix it very well after it has cooled to get even measurements. Why would this occur if stratification can't occur in a well mixed fluid before the sample is taken? I do note using a clear fermenter that's conical for 95+ % of my brews that cold break does...

Why can I get different gravity readings from the same sample pot when I take samples of wort. Using electronic refractometer and with the temp stable. Mixing the sample thoroughly ensures all of the readings are the same. If not mixed obvious differences between top and bottom of the sample?

@pocketmon Reading through your most recent post, you mention gravity drop noted as temp falls prior to pitching the yeast. I suspect that this could be caused by wort stratification, the denser sugars will fall and the wort near the surface will be less dense. Once ferment starts gravity...

@bwible Re mini kegs for ale extraction with beer engine. This is what you need. https://rlbs.ltd.uk/5-ltr-mini-keg-cask-read-ale-extractor-for-hand-pump.html I've heard the mini kegs can rust after a while, the stainless 4 litre kegs seem to work well if vented adequately. I was beaten to the...

Looks like the opening setup for a game of 1/4 inch barbs draughts.

Gas line diameter doesn't matter, provided it fits. Yes CO2 prolongs " cask" life but not true cask ale. Not sure about black mould, can't see how it could be inside regulator or lines unless contaminated. If on outside clean off with bleach etc. Do use a large diameter beer line though to your...

@Yooper Over 1200 posts in this thread and a load more on the UK thread. Think of it as enrichment and you won't hate the transition at all.

Avoid the early style all metal with a gauge and wobbly twiddly bit on the end. If you do have or get one of these take the threaded twiddly bit out, add lots of PTFE tape so it becomes stable when you put it back in.

If you want a little more complexity you could attach bulkhead ball lock posts to the inside of your jockey box and then use ball lock connectors to attach / detach the towers. This would mean no liquid leaks when you disconnected. But I'd err towards the simple duotight or equivalent...

The glass lid is steam tight.

A grainfather !!

No idea with the esp32 and ADC. I felt it was all a bit slow with the 8266 and pressure, I've got the esp32 ready to build the system again for pressure.

I found it needed finings to get it really clear. But liked it's speed and usability.
