Spike Brewing | 4” Tri-Clover Clear Polycarbonate Cap

Probably the coolest add-on for Spike's conical line! Spike has 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 Spike is not one to stop that curiosity so here is the solution to that problem.

Spike's 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.
