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

What’s Included ✅

• (1) MiniBrew™ 13.5G Open Top HDPE Conical Fermenter Body (open-top molded design)

• (1) Seated/removable lid

• (1) Food-grade Buna-N gasket

Includes the same standard hardware setup as the 13.5G base model:

• Racking port: 1/2" EZ Seal + 1/2" SS hex nipple + 1/2" SS full-port ball valve

• Threaded racking port filter (included)

• Dump port: 1" EZ Seal + 1" SS nipple + 1" SS full-port ball valve

• Cork + airlock included

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.
