This looks pretty cool. I may replace my Speidel with it if gets good reviews. My main concern would be not enough headspace.
I can’t imagine why anyone would want to ferment in a clear fermenter.
If it’s in a chest freezer, does it matter? Do you take the fun out of everything? 
I have seen beer skunk in as little as minutes. All light matters.
Cool. Back to the caves I suppose…
Isn’t it mostly ultraviolet light that skunks beer? I like to see what’s taking place, I know what is happening but still love to see it. I do not harvest yeast so the Catalyst is not something I would look at getting but I have thought about switching to some sort of wide mouth plastic fermenter.
I don’t like the price. They don’t have handles which mean moving it outside of the stand would be a PIA and the stand is too big for my chest freezer.
I transfer directly from the spigot of my speidel and I always end up transferring some yeast. Even if not reusing yeast, it would be a benefit for me to remove the yeast completely before transferring. I guess I should just be looking for a conical in general…
Both great points. Moving it would be PITA
A VERY hoppy beer in direct string sunlight, yeas…I’ve seen it in as little as 5 minutes. But I can’t see it being a problem in 99% of cases.
The only experience I have with skunked homebrew is when I have been outside on a sunny day with it in a clear glass. This is the least of my worries…
Is corona a very hoppy beer? How about ever other beer in clear or green bottles.
I have thought about the same thing. A conical of some sorts would be cool. But I agree, moving this thing around seems awkward. Getting it down into a chest freezer for fermentation would be interesting.
How do you like those Speidel fermenters anyway?
No, and it also won’t skunk in minutes. When I used it for a BJCP exam it to 5-7 days to truly get it skunky. And no matter, it’s still a lot longer than a clear fermenter going into a closed chamber would be exposed to light.
I love mine. I have adjusted to get a higher final volume however I am still trying to eek out as much beer as possible which leads to some yeast transfer. I may have to increase my volumes again so that I get more than enough.
Interesting… I have had helles, and pilsners go skunky in less than 5 minutes.
I’ve heard that (skunking in 5 minutes) from enough reliable people to believe it even if I haven’t experienced it myself.
As far as Corona, Heineken, etc. those clear/green bottles get exposed to light for a lot longer over the course of packaging, transit, retailing, etc.
I’ve never had a lightstruck issue with my clear fermenters, after 20 years. It’s simply not an issue, unless the fermenter is exposed to direct sunlight through a window or something. Even ambient indoor lighting…not an issue. Two benefits of fermenting in a clear fermenter: 1) You can see if the krausen is about to overwhelm the airlock early on during fermentation, and so you have time to sanitize/install a blow-off rig before the fermentation explodes all over the place. 2) You can see how far down you need to place the siphon tube when racking into a keg or secondary so that you minimize trub transfer.
Interesting. Northern Brewer claims that fermenter is exclusive to them.
What’s wrong with clear fermenters? I have 2. Fermentation occurs in the darkness of my chest freezer. So, no light struck issues.
A minute or less for me. Hoppy beers in strong sunlight.
Edit - in London I tried to get a summer ale to skunk by having it in direct sunlight the whole time. It never did. Somwas that the latitude, the amount of hops, type of hops, whatever it never skunked.
IPAs on my deck will skunk quickly.
