Probably the coolest add-on for our new conical line! We've heard many brewers who have switched from clear carboys to stainless and they only have one complaint; I can't see my beer fermenting any more! Brewers are curious by nature and we're not ones to stop that curiosity so here is our solution to that problem.

Our engineers designed a clear polycarbonate (same material as bullet proof glass) cap which allows you to see inside the top of the conical when it's fermenting. This has also been tested against common brewery chemicals and has held up against the likes of PBW and StarSan.
