MiniBrew™ 13.5 Gallon Conical Fermenter

More capacity. Same clean MiniBrew workflow. Built to upgrade. 🍻
Made in the USA • 60º Conical Design • Food‑Grade HDPE • 4" Top Port

Big‑batch conical fermenting — without the commercial headaches ✅

The MiniBrew™ 13.5G lets you scale up while keeping the process simple and repeatable. You get the same proven MiniBrew conical workflow—dump, rack, and transfer with control—plus the extra capacity to double recipes, run bigger batches, or give high‑activity beers more room.

Start with the base model hardware and add only the upgrades that match your process as you grow.

Why the MiniBrew™ 13.5G works so well ✅

True 60º conical design

The 60º cone helps yeast and trub collect where they belong, making sediment management and transfers more controlled and repeatable.

One‑tank brewing workflow

Ferment, dump, rack, and transfer from one vessel—fewer steps, less agitation, fewer chances for oxygen exposure.

Big 4" top port

Easy access for cleaning, krausen removal, and dry hopping. A huge upgrade over narrow‑neck fermenters.

Tough, brew‑day practical

Made from food‑grade HDPE (high‑density polyethylene) with smooth interior walls—lightweight, impact‑resistant, and much safer to handle than glass.

Standard hardware included (base model) ✅

(Same hardware setup as the 8G conical)

• (1) 1/2" EZ Seal weldless bulkhead

• (1) 1/2" stainless NPT threaded hex nipple

• (1) 1/2" stainless full‑port ball valve

Bottom dump port (1" NPT)

• (1) 1" EZ Seal weldless bulkhead

• (1) 1" stainless NPT threaded nipple

Temperature monitoring 🌡️

Fermentation ready

Open‑top lid option (sold as an upgrade kit) 🧼

Prefer open access for cleaning and additions? The Open Top Lid Upgrade uses the same tank, same hardware, same fittings—the lid style is the difference:

• Open Top Lid: removable lid seated on the top of the fermenter

• Includes a Buna‑N gasket for a proper seal

• Does not allow CO₂‑pressurized transfers (open‑top configuration)

This is offered as a separate upgrade kit product, so there’s no need for two variants.
