This is normal if the load is removed. The SSR go into a high impedance mode (they never truly open), but can "leak" a 1mA on the output when in an "off" condition. If there is no load on the output of the SSR you will see full voltage on the the output of the SSR, in your case 120vAC. If you...

I do that and it does help. I sometimes wait until I see the judges comments. Most times I really don't care what they have to say, I just want a medal. But if I taste oxidation, I know I screwed up somewhere.

This is easier said then done, I wish it wasn't. I open my fermenters, but before I open them, I flow co2 into them and out another port into a airlock(I have 2 gas ports on my fermenters). The pressure is lowered to 1-2 psi and then I open the fermenter. The positive pressure is kept on the...

If your just getting started with home brew comps, there is a strategy to competing. One of the most common defect in home brew comps is oxygen ingress and people have a tendency to brew and bottle way too soon for a competition. The beers need to be timed so they are at their best when judged...

34/70 is a German yeast. All lager yeasts originated in Europe, even the yeast used by Bud, Coors, Miller etc. That being said, I won multiple silver medal at the NHC finals with that yeast. The NHC BOS beer in 2021 was a extract American Lager made with 34/70, I got second to him with the same...

I agree. I do starters with 34/70 and I've had the same experience, I think the yeast need time to "wake up". I typically just throw in one packet into a 4 liter starter for 12 to 14 hours, chill, decant, pitch. In a 7 gallon batch @12 plato the lag times are 16-18 hours. BTW, 34/70 is the...

That's awesome! I've always wanted to visit that brewery, really cool setting. You should be stoked, it pretty cool to say "that's my beer on tap". I'll try to make it there and try your beer. I just brewed a beer at StormKing just a down the road. I won BOS at the MN State Fair for a German...

I'm not going to argue with you any more. As I said in the past I'm very experienced on these types of system. I had an inspector crawl up my ass on the very things you said were wrong and I passed, he even complimented on the quality of the build. We could argue until eternity and it would do...

I have seen those old designs and I don't recommend them. Two SSR's opens the circuit completely and is, in my opinion, safer. I apologize if I came off a bit arrogant. Yes, I did consider it and it will work, but I would change a couple of things in it. I also was responding to false...

You would use the breaker in the electrical panel. It's done all the time. You can put the switch in there, but it's not necessary. GFIC are a poor substitute for a good ground and proper maintenance. The ground is your best defense against accidental electrical contact, even more so then the...

Most SSR's turn on at zero cross over, so when they get the signal to fire, they wait until the voltage is at zero and they fire. When the fire signal is removed, the all SSR's cannot turn off until the voltage/current is zero (cross over). Both legs of the circuit need to be on in order for...

Huh? How do you control current if you don't control the voltage? You have a fixed load impedance I'm assuming, right? If the voltage isn't removed how do control current? Magic? Ohm's law is officially suspended. What you're confused about is called leakage. The SSR will have voltage on the...

Why do you need both switches. Your SSR is a switch. It's redundant. Yes. Both legs are removed from the circuit. I would not have passed my inspection in a commercial setting with both legs being controlled. No sH1+. What do you called it? it's commonly referred to as a coil to avoid...

I'm wondering why you put a mechanical switch in line with the SSR/heater? Typically there would be 2 SSR's in the circuit, one for each leg of the 240Vac circuit. Two SSR's adds a safety element to the heater, because even when it's not being fired, there is still one leg of the circuit that is...

I have expressed my opinion about SNS on the AHA forum and I was pooed-pooed. But the reason SNS works is very simple. You're pitching at high krausen. This is not a new concept, it's been around for a really long time. When yeast is at full krausen is extremely viable. The key to a good pitch...

Each yeast will land at a general pH when the proper pitch rate and fermentation conditions are met. So the idea that you can mitigate a pH rise from selecting yeast that produces more acid is valid and very practical. In my experience I found that Chico strains have a finish pH of 4.4 or so...

This is probably the best solution, but not the cheapest. You can ferment with or without pressure, do closed transfers or ferment and serve in the same vessel. They are made from stainless steel and last forever. You can use a floating pickup in them. They are easy to clean. Easy to sell later...

Yeast in storage should be kept away from oxygen as much as possible. When stored yeast comes in contact with oxygen it will force the cell into metabolism by using up it's glycine reserves. Once these reserves are used up, the cell is kaput. Although it may not be sexy, a mason jar with a nice...

I guess I have observed something different, although I brew mostly pale beer. I don't measure mash pH until 10 minutes, mostly because I haven't had a chance to do it and I figure it will take some time for the mash settle into it's pH. The difference in pH from 10 minutes and 60 minutes is...

1. The strips aren’t very accurate, a calibrated pH meter would be better to get the most accurate numbers. 2. The pH of the water isn’t really impactful unless it contains high alkalinity or has a good amount of buffering capacity. RO water is very low in minerals and would not have much in...
