MiniBrew™ 40 Gallon Conical Fermenter

One-barrel fermentation, simplified. 🍻
Made in the USA • True 60º Conical • Food-Grade HDPE • Lid-within-a-Lid

Professional craft brewing — without the commercial complexity ✅

The MiniBrew™ 40G Conical Fermenter is built for one-barrel batches and serious small-scale production. You get the practical advantages of a true conical—cleaner sediment separation, easier dumping, and controlled racking—while staying lightweight, easy to clean, and built to upgrade as your process grows.

Why the MiniBrew™ 40G Works So Well ✅

True 60º Conical Bottom

The steep cone helps yeast and sediment collect where they belong for more controlled dumping and cleaner racking.

Lid-within-a-Lid Convenience

Make ingredient additions (dry hops, nutrients, finings, etc.) without fully removing the main lid—less disruption, faster workflow.

Tough, Brew-Day Practical

Made from food-grade HDPE (high-density polyethylene) with smooth interior walls—lightweight handling and easier cleaning compared to stainless at this size.

Built for Real Production Cycles

Designed to simplify the parts of brewing that get painful at larger volumes: cleaning, dumping, transferring, and repeatability.
