Catalyst Cover

Great fermenter. Easy to use. Decants right out of the fermenter to the keg with minimal sediment. I have read other reviews where brewers were disappointed because it did not seem to reduce the volume of trub. The solution is to leave the valve open on the bottom with a twelve once wide mouth mason jar attached. Spent yeast / trub collects in the jar leaving the sides clean. Then, with the added stopcock, it is simple to dispense to the keg without a separate racking cane. Bottom valve should be left open to mason jar during brewing. If you open it add the end, it sends an aerating cloud of spent yeast into your brew making an unnecessary side clinging mess. This fermenter has proven so clean, I have not needed to transfer to secondary as long as the described technique is used. Supplemental stopcock is great, but plastic is hard, so use care when drilling to avoid chips. Best fermenter I have tried.

Perfect addition to the Catalyst Fermentation System; makes lifting it pretty simple, and helps to keep that wort warm. Make sure you put it on BEFORE you have the bottom trap valve attached and have dumped your wort into the system :) One of those "oh, crap" moments :)

You'll want to purchase this item to add to your brewing with the Craft A Brew Fermenter. I found the cover helps stabilize the tub a bit more in the frame, and helps prevent it from sliding around. There are velcro tabs which you can attach to the frame and really keep things from moving around. I found the cover is a little difficult to slide onto around the tub, but overall is good to have. Plus you won't need to worry as much about keeping your batch in a darkened room as it ferments for 2 weeks.

works as advertised. it is a bit annoying to put on, and of course it is annoyingly hard to see inside this thing even with the little peek window.

First time user ,got best result. easy to clean and perfect instructions make easy to use.

Seems well built but I haven’t gotten to use it yet. I had planned on putting it on my tank that had my wort fermenting in it but it wouldn’t fit over the butterfly valve housing. But I’ll update my review once I can put it on. With today being bottling day and tomorrow being another brew day I should have an updated review soon!!! Update. I love it. Make it easy to carry if necessary, has a window that lets you take a peak and is durable. Only thing that’s annoying and it’s because I’m forgetful is you have to make sure you have it on before you transfer your wort because the bottom valve has to be taken off to put it on but that assures a perfect fit.

A great tool for any brewer. Especially helpful where space is limited. Cleans up well and gives you better beer!

This is a replacement, after a year I washed my 1at one and it fell apart. Dont laundry it.Dosent cover the Mason jar at the bottom.I'm in ti 2 years now and no skunky light struck brew yet. 5 thumbs up.
