It seems like the control of a valve is more linear than an on/off switch. Without the 'in-between' settings that an adjustable valve can offer, PID control is really only proportional and integral, but not derivative (or so I'm told by much smarter engineering types). Solenoid gas valves...

Last I read, they are working on a higher temp one, but no idea when that will happen.

Hi all, I'm wondering if anyone else would be interested in contributing to an open source automated brewing system that uses propane for heat. I'm interested in doing something similar to the HABS (halfluck automated brewing system), however I want to use propane as my heat source. I also want...

What about a liquid level sensor https://www.sparkfun.com/products/10221

Cool, thanks for the validation :)

Hi all, we go through a lot of mill around my house, so I was thinking of something to do with all of em. Could I stick a stopper on the top of one and use it as a small fermenter for experimentation? Thanks JR

So... I've been wanting to make a fermentation chiller/kegerator, so I found someone on craigslist who has one. I borrowed a truck and a friend, and went to the lady's house that was selling it. Unfortunately, she was a full-on hoarder. Had to bushwhack our way through her garage to get to...

How does one use gelatine? Just normal knox gelatin? How much?

I tried some yesterday, it didn't seem *that* bad - actually it was pretty tasty as an IPA, but had some 'homebrewiness' to it - kind of a tannic flavor. I'll bottle later this week and chill it in the bottle. Any recommendation on what temp to chill to? I used a whirlfloc any...

Thanks guys, I've already done my dry hopping, after 2weeks of fermentation at 60-70. In adrddition stable hydrometer readings for 4 days before I introduced my hops. That's been well over 4 weeks ago now. I was thinking of bottling today anyway, and just living with cloudy beer. Should I not...

My ipa has been in the fermenter since labor day - more than 6 weeks now. It's been in water to keep cool, and I kept ice in the water ,which kept it to about 40f for a few days , but has stayed about 60 for at least 4 weeks . What can I do to clarify , or conversely, shall I just bottle it...

Are there convenient ways of 'downsizing' standard 5g recipes? I'm using brewtarget, and it doesn't appear to support easy translation from 5g to any other size recipe.

I hear that, but if I buy any more kit in the near future, I will raise the ire of the home goddess (i.e. my wife) and SHE will severely punish my for my disobedience (and not in a good way) ;)

14 lbs. I was trying to use the 1.41qt/lb mash thickness.

Thanks Strat. The recipe calls for 1.41 qts/lb in the mash tun. Just so I understand your suggestion though: I could mash with less water and sparge with more? If the case, doesn't having less water in the mash and more in the sparge fiddle with the chemistry a bit?

I looked around and didn't see an answer to this question: What do you do if your mash doesn't fit in your mash tun? I have a 5 gal beverage cooler I picked up from Home Depot for $10 (it was missing the spigot, which I intended to remove anyway). So for my 2nd AG batch ever, I wanted to...

:ban:

Thanks, It looks like yeast, and my airlock has bubbled - as evidenced by the level of the vodka meniscus. My concern is that the blobs of yeast ( I think they're yeast) at the top seem to be growing. Could it be brettanomyces (or some other wild beastie)? What's the best course of action...

Racked my beer to my secondary, and now there is a bunch of odd-looking stuff floating on top. First, what could it be? Second, is my beer ruined? Third, can it be saved? Many thanks, James

Thanks, that makes me feel a bit better. Funny story on the yeast, I had the grill on because I was drying some of the leftover grist, so I could feed it to my chickens :) I put it in the grill so it would keep warm, but even with only 1 burner on the lowest setting, away from the burner, it...
