## Questions & Answers

**Q: When you unscrew the mason jar, will it be completely full and spill everywhere?**
A: It can drip a bit. On YouTube on the CraftABrew channel there is a video that shows a demonstration. They place a small bowl under the mason jar to catch any excess. Expect the jar to be full, which is a good thing in terms of reducing gas in the headspace of the jar.

**Q: Is it possible to use it to decant the trub after boiling the mash? Is it high temperature resistant?**
A: Ely F, This was a gift to my son in law, so here is his answer to your question.: But, yes it collects all the undesirables, he can’t add boiling liquid to it. He’d have to chill the mash to 70-75 degrees. The Catalyst will withstand the temperature from a dishwasher, but if they are asking if they can pour boiling hot wort into it, they should use a wort chiller before adding it to the Catalyst.
16 oz. mason jars are recommended for collecting the trub. After that, 8 oz jars are recommended for collecting yeast if they choose to reuse it for future batches.

**Q: How do you clean and sanitize the lid?   Do you have to remove that gasket to effectively sanitize it?**
A: The removing the gasket is the easy part, getting the gasket back on while it's slippery from Sanitizer is the harder part. But seriously it's not anywhere as troublesome as trying to clean an old school carboy or sanitizing and using the autosiphon. I just flip the lid upside down with the bung in it, support it so it stays still and pool my sanitizer in it like a shallow bowl.

**Q: Is this PVC?**
A: The tank is made of Tritan which is a medical grade polymer that is completely inert and can withstand temperatures unto 230F.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Absolutely love this product!
*by S***N on March 10, 2019*

To keep is short, everything came packages well. Assembly was 15 minutes tops and super easy. I love having a visual on my brews in progress, it is honestly a game changer. The valve and mason jar on the bottom is also great because its simple enough to operate and remove the trub and excess materials from the beer. The top latches down easy enough and the plug at top works great.For the plug, I personally had it in hot water with Star San along with blowoff tube so i could put slip the tubing in easier. It is a hard plug. Let the plug cool before you try to push into the cover hole, it may slip through if you push too hard. I may have done that, but once it cooled its perfect.The biggest thing I found on other threads it that people are installing the valve upside down. The handle, meaning the piece you grab, should be pointing down towards mason jar/floor for the valve to be fully open. If you put it on the other way, the handle will hit the container and not open fully.Once again, love this product. Will recommend to everyone and will personally be buying another in late spring to get the summer brews going! Happy brewing everyone!

### ⭐⭐⭐⭐⭐ An amazing product
*by D***L on July 3, 2024*

I'm fairly new to brewing my own beer. During my journey of discovery I've learned that the single biggest obstacle to a "REALLY" good batch is sediment. Hops sediment, to be specific.The brewing process requires that you move the wort (or unfermented beer) from the cooking vessel to the container it will reside in during the fermentation process. Then you need to transfer it again to a vessel where the sugar solution is added, and yet again into the bottles where the batch will finish.The goal is to reduce the amount of sediment in the wort during each transfer. This is NOT an easy task - invariably, some sediment is always transferred, which shows up in each bottle of beer.The Catalyst, however, completely removes sediment from the equation. Sure - there will be sediment from the transfer from the cooking vessel, but the design of this system allows the sediment to settle into a mason jar that you can easily segregate from the brewed batch to dispose of. It's so easy to add the additional fermentation sugar and to load up individual bottles from the Catalyst.This device has been a game-changer for me and my hobby. I can produce beer that is completely free of any sediment, and rivals any commercially available product for clarity.Also, just wanted to add that Craft A Brew is an amazing company. Their customer service folks are VERY smart. And patient. They LISTEN to your concerns, and are more than capable of offering really helpful advice. A really good product from a really good DIY provider. Whether you're experienced, or a newbie to home brewing, you just can't go wrong while working with the Craft A Brew folks.

### ⭐⭐⭐⭐⭐ Two Year Review
*by B***  on January 9, 2025*

I have been brewing in this continuously for the past 2 years, and it has held up well. The gaskets are holding up well with no dry rotting, and the construction is still sturdy. I recommend using a tilt/digital hydrometer to not have to open the lid to check gravity while brewing. The conical shape and easy trub removal makes for some clean beers, though I recommend having a second wide-mouth mason jar to quickly swap on when removing the trub to reduce chance of infection. Great purchase!
