My son and I brewed a 10 gallon batch of blonde ale on Friday and got to christen my Catalyst fermentors. I just emptied the trub jars for the first time today. I'm impressed with the looks and design of the Catalyst. I put two aluminum pie plates under the Catalyst, removed the jar, carried the jar and one plate to the sink and left the other behind to catch drips. I emptied, rinsed, and sanitized the jar. I squirted some sanitizer into the valve area for good measure and reattached the jar. I'm sure I'll have to do this at least once more before kegging. Very slick system.
