MiniBrew™ 13.5G Open Top Conical Fermenter
Open-access fermentation for easy cleaning + additions 🧼🍻
Food-Grade HDPE • 60º Conical • Includes Seated Lid + Buna-N Gasket
This is a different tank — not a conversion kit ✅
(Sold as an Upgrade Kit to the traditional style 13.5g)
(Must be purchased in addition to the Standard 13.5g Conical Fermenter)
The 13.5G Open Top is a separate fermenter body that’s molded as an open-top design. You cannot convert a closed-top 13.5G into this model by swapping lids.
We list it as an “upgrade option” to keep the product page clean—but what you’re purchasing here is an entire open-top fermenter configuration.
Why Choose Open Top?
Open-top fermentation is all about access and simplicity:
-
Fast cleaning with wide open access
-
Easy additions (dry hops, fruit, oak, spices, nutrients)
-
Hands-on fermentation workflow (great for frequent access)
-
Same conical performance with a 60º cone for trub/yeast collection

Important Note About CO₂ Transfers ⚠️
This open-top configuration is not designed for CO₂-pressurized / closed transfers. If you want CO₂-assisted transfers into purged kegs, choose the standard closed-top 13.5G model instead.
Compatibility
-
Designed as an Open Top version of the MiniBrew™ 13.5G conical system
-
Hardware/port workflow matches the 13.5G platform for familiarity and upgrades
Want the easiest access possible? This is it. ✅
If your brewing style benefits from frequent access for cleaning and additions, the MiniBrew™ 13.5G Open Top is the most hands-on, user-friendly way to run a bigger conical—without the friction of a closed-top workflow.
