What kind of sprayer hookup is that? (the one with the green hose) I apologize if you mentioned it in the video...I'm at work so I didn't turn the sound on.

I picked up a chemical engineering degree, so I fall smack in the middle of this one. In fact, I think brewing helps me with the fact that I don't use any of chem eng training on the job and it gives me a way to geek out at home. All my friends who brew are engineering types as well, but that...

Not to sound a little anal, but I would change one variable at a time to understand what the problem was. If you change multiple things, you'll never know. If its a yeasty taste/smell...start with the yeast change and make a small 1-2 gal test batch. Second, chlorine could throw in an off...

Thanks for the info on the homebrewing pumps. I've dealt with industrial pumps and wasn't sure what sort of head these produced...and it seems like there is truly not much to worry about. Eventually I'll get to the point where I have a fun pumping system set up to play with, but I'm not there...

While you won't do any short term harm to your pump, where the valve is located matters. I assume this is a centrifugal and not a positive displacement type pump. If the valve you close is on the inlet side of the pump, you won't increase line pressure, but you could cause cavitation in the...

How do you guys account for the expansion factor between cold and boiling liquid?

Also check out a recent podcast from Basic Brewing Radio. They actually discuss refractometers and hydrometers. There are many reasons it could be off and the guest is well versed in the science behind it all.

Checkout the following thread: 6 Day Beer Attempt!!! I made a beer in 6 days and it turned out quite tasty. it was a nut brown partial mash. In addition to the recipe, there is a healthy discussion on the fermentation and yeast flocculation. I would recommend a heavy cold crash in a...

Hmmm...and here I was thinking Blonde. I guess I didn't think it was hoppy enough for a pale, but that's why I asked.

HAAA!!! I forgot to mention that I am doing a 2.5 gal batch to test it out! Not like that's a crucial detail or anything...

Hey folks... My parents really enjoyed the Aussie Light Ale from Midwest Supplies. I am going to borrow and tweak the recipe but am having an issue trying to characterize the style. What would you guys characterize this recipe as? I have a guess but don't want to taint your thought...

THE RESULTS HAVE BEEN TABULATED!!!! I was worried Saturday night. The beer still had a heavy yeast aroma and flavor. It had carbonated nicely though. However, on Sunday morning, I pulled a draft at 8 am and the aroma/flavor had died off to barely noticeable!! By noon you could hardly tell...

Even after this, I'm still going to go with letting the beer sit on the yeast cake for a few weeks to clean things up as suggested in other threads. I've had good success with the 3 week brewing process (all primary). This was more needs based and a fun little experiment to try. I pitched two...

This morning (8/19) the SG was down to 1.013 which was the target from the previous recipe. The yeast activity had died down and cleared slightly. I moved the fermenter to the kegerator to chill it and facilitate the flocculation. So far so good...

Last night, 8/18 at 5 pm, the SG was down to 1.016 and the bubbling rate was slowing. My original recipe was 1.013 so I'm thinking this should be able to finish off fermentation today. My plan at this point is to get to target SG today and cold crash the fermentation in my kegerator through...

Thanks for all the input folks! I will definitely look into the gelatin as an option. I am also looking into the differences between gelatin, isinglass, and biofine. One of those may do the trick to help drop the yeast fast after the ferm is done. I will also check into the cold crashing to...

I decided to have all the guys over while the gals hold my wife's baby shower. It was at this point that I realized I would not have enough beer to handle everyone. What's a brewer to do?? I took my newly developed Nut Brown recipe that I brewed as a 2.5 gal AG (tried it once and it tastes...

Not only my first all grain, but my first original recipe. Nothing too special, mind you, but mine nonetheless. I've been dying to develop my own nut brown since its my wife's favorite! So, I used the countertop partial mash set up for the first time, but I decided to do a 2.5 gal all grain...

Was it Ralph the Wonder Llama or one of those 142 mexican whooping llamas...I wonder?

Chemical Engineer - Mich Tech '04 My job doesn't delve much at all into chem eng so I guess my hobby took over that part of my brain...
