Oh boy, I've done that once myself and was pretty disappointed. Sorry to hear it! Is your other electrical on GFCI breakers? That shouldn't happen if it is and that would cause more alarm for me. I transfer now attaching a triclover to flare threading and hook up my CO2 tank on 2ish PSI. This...

I wipe down my chambers every so often with lysol to get that funk out. If dampness becomes an issue small dehydrators go for cheap, depending on your location. I got a 20 dollar u.s. unit and it pulls about a liter out of the chamber during active fermentation and that's moisture not supporting...

At 70 I wouldn't bet it'd be fusels. Letting it cool overnight isn't a problem and wouldn't cause higher alcohols. It may be an issue that could be resolved with time.

I'm interested in trying these out. Could someone with access please PM me?

Do you know the fermentation temp? OG? FG? Sounds like conditions ripe for higher alcohols (fusels) but sometimes people conflate some phenols and ethanol with them. There is no fix for fusels, when in they are in. Time will meld it into the background but as you mentioned, a hoppy beer doesn't...

"This was yeast collected from the bottom of the secondary carboy. This explains why there is a lot of other material beside the microbes. Sometimes you can see huge chunks of hop material." Got it, but before the brew what health condition were the yeast in? That's what I was asking for...

Sadly in my experience you get what you pay for with these. I've bought several iterations of the one you showed in a link and they are all a waste of money. I haven't ponied up the money for the 180-200 dollar ones only because I am able to borrow one from a friend but the difference is night...

first off, congrats poster on your acquisition of a microscope. hottpeper is right that rods would definitely be the most common bacterial infection to find but I think a lot of what is being looked at is debris. bacteria are often significantly smaller than yeast. there are tiny specs that are...

What mongoose said, beat me to it. Volume can also play a role in slight changes in temps. A 3 gallon batch will cool faster than a 5 gallon batch. I often press the probe between two ferementers and weatherstripping over the tip not in contact with anything. It helps to split the difference...

limulus, i am generally aiming for 55 to 75L (14.5 - 20 gal) depending on the batch. with the auto-sparge and manifold i can keep the mash filled 3 inches above the grain bed and there is plenty of wort in the conical. with this method i have a main fermentation in the vessel and i always...

This activity is part of a research project for a thesis in biology. That said, I've been working with brewing microbiology since before the program very much for the fun of it.

Here are a few images of the early process. Samples are collected (like at the shown hop farm in Yakima), and dropped into a growing medium (maltose, yeast nutrients and vitamins, ethanol) and incubated at low lager and ale fermentation temps in separate units. Flasks that produce CO2 are noted...

I figured in the interest of keeping my research "open" I would share my progress with the community here. The project examines the types and varieties of organisms found in natural and human environments around central Washington state. I've collected samples of soil, bark, flowers...

Well, I'm months behind in getting back with pictures of the setup but here it is! I finally have a phone with a camera again. Image 1 shows our setup on a typical brew. We now mash with the colander raised to the second handles and use the auto-sparge to keep the grain bed submerged. We can...

I don't doubt you have had success with high temp fermentations. You are an experienced brewer and am aware of your attentiveness to the process. I should have worded my explanation to say since saison yeast are commonly fermented at high temperatures, they are commonly associated with...

Chickypad is spot on with everything said. Saison yeasts tend to put fusel alcohols into your beer more than others. Your brew process was less likely the culprit than I suspect fermentation temperature or yeast health. Fusels aren't generally repurposed but conditioning has helped beers I've...

That's an excellent meter, I have one myself and good job on the price! I have tested that next to their more expensive model and have always gotten within 0.1 but often spot on. The electrode can last longer if cared for. A couple of things I do to maintain it: Keep it stored in either storage...

To add to augie, the equipment should also reflect the kind of beers that you make. I have seen some fancy setups costing many thousands of dollars owned by people that make pales and IPAs, using single infusion mashes 100% of the time. This is overbuying as far as I can tell. A simple design...

hgearle, I had a feeling my results were skewed with the light grain load. Though I don't make high gravity beers all too often, most of my grain bills are about the same weight but for a larger volume. I won't brew for another 2 weeks but I will be sure to continue to explore this with you and...

In the works friend. I have a set of photos on my sweethearts phone I is Brewha but we have made some additions to the system to dial it in for our needs. I will share when I'm back.
