The promises have been pretty clear, and universally unmet, for about a decade. I don't think anyone has a problem with optimism, but when I hand you money, it's called a contract. And when my dopey neighbor runs into something (nearly me, one time) while on "full self driving", it's called a tort.

if bottle pressure matches keg pressure*, you will get no bubbles, but also no flow. Typically you can a get at least a couple PSI with no foaming, but it may be a little slow. *Assuming keg pressure is at equilibrium with beer vapor pressure, i.e. the pressure the beer "wants ro be at". You...

Apologies for what may be a silly question, but did you purge and pressurize the bottle prior to filling? The fillers have a trade-off between speed and foaming, which you control via managing bottle pressure.

Your are correct that the pressure will drop when cold crashing, but the dissolved CO2 will actually increase as headspace CO2 is absorbed into the beer. Unfortunately, the absorbtion process will take a week. This means it will be harder to accurately estimate the dissolved CO2 already in your...

Post in thread 'Keg purging with active fermentation' https://www.homebrewtalk.com/threads/keg-purging-with-active-fermentation.628658/post-8004741 That's a famous thread around here. Doug made a lot of overly conservative estimates and assumptions to arrive at 5ppb O2 (gas! so several more...

This would be technically true in an ideal universe (with zero friction, everything is a sphere, all collisions are fully elastic, etc). In the real world, your fittings and tubing are letting enough O2 in that you'll never approach the ideal. Further, the difference between 1ppb gas and...

It's not in town, but Aying has Ayinger, and is supposed to be a nice day or night trip. I had Ayinger Dunkel from a keg and I'm still chasing the flavor. (The bottles are total garbage in the USA - I keep finding 6mo+ old ones.) Some german here didn't think highly of Ayinger. But they also...

I don't think it's surprising that hot fermentation gas makes it smell like hops*. Particularly if you're doing dry yeast or lager with a slower start (more contact time.) A lot of people don't have the issue because they're just sanitizing a keg, emptying it, and then hooking it up to ferm gas...

I'm more concerned that sound = wear. I don't really want micro/nano ptfe in the starter. I probably don't care if the stir bar disintegrates beyond that.

Just visited Marshall's Wharf Brewing Co in Belfast, Maine. A pleasant surprise! I was suspicious of a pilsner "made with maple sap instead of water", but it was quite good, and not in a maple syrup way. A couple of others had some odd twists (a hint if peat in a brown ale), but the beers were...

I sometimes put a towel or pot holder between the stir plate and the vessel to shut it up.

IMO you can purge with ferm gas, or purge via displacement, but both is redundant. I'm skeptical that you can approach the theoretical endpoint of ferm gas purging when using real-world tubing and fittings. Starting with an already-low starting O2 concentration (by using the first 5 gallons of...

I'm so confused. How are people getting hops in the star san? Are they not starting with a clean keg? edit: Wait, are people displacing star san with ferm gas? I thought of a fairly crude comparison to contraception, but I'll keep that to myself.

I'd be tempted to use some of those diesely NZ hops with a NZ Sauvignon Blanc. But maybe that's a bit too on-the-nose? (No experience. I had a hopped mead, but it wasn't my cup of tea.) edit: corrected varietal, wrote cab sauv at first

If you're looking to grow it, skip Kingston Black. I don't know much about growing apples, but I know that one's a nightmare. Edit: To elaborate, it is very hard to train/prune (it wants to grow in a strange, sparse habit), is highly susceptible to basically all major apple diseases (be...

I really like Porter's Perfection, enough that I have a couple grafts of it in my otherwise edible apple yard. It is growing great despite sub-optimal light. Golden russet is a great, edible sharp.

Do you have a month an an interest in learning to streak agar plates? lol

Yeah, I'm imagining the battery is low enough some reference voltage is drooping. Odd that BAT or something didn't come first. edit: it uses a CR2032, so that's nice at least.

I have a Kegland KL18388 digital pressure guage in a blowtie 2, and it has started reading "OP". I would think it means "Over Pressure", but the valve is full-open, so not quite 0 psig, but well below 1 psig. This seams like it should be easy to google, but I struck out. Maybe low battery...

Cool!
