FermZilla All Rounder Fermenter

The FermZilla All Rounder is a pressure-capable conical fermenter built for home brewers and winemakers who want more control over the entire fermentation process, from pitching yeast to packaging a finished, carbonated product. Constructed from durable, food-grade PET plastic, the vessel is available in multiple sizes to suit everything from small test batches to full five-gallon runs, and its conical bottom with a removable collection ball makes harvesting yeast or separating trub and sediment simple and mess-free. The clear body lets brewers visually monitor fermentation activity, krausen formation, and clarity without opening the lid, while the robust O-ring sealed lid and fittings allow the unit to hold pressure, enabling spunding and natural carbonation right inside the fermenter itself.

What sets the All Rounder apart is its modular, upgradeable design, which lets it function as a basic bucket-style fermenter or be expanded into a full pressure-fermentation and dispensing system. Brewers can add a pressure kit with a spunding valve to manage CO2 buildup during active fermentation, attach a carbonation cap for force-carbonating finished beer or cider, or install a racking arm to draw clear liquid straight from the vessel without disturbing the yeast cake below. This adaptability means a single purchase can grow alongside a hobbyist’s skill level, supporting techniques like cold crashing, dry hopping through a removable lid port, and closed-transfer kegging that were once reserved for commercial-grade equipment.

Built with practicality in mind, the FermZilla All Rounder includes a sturdy stand or cradle to keep the conical shape stable on a countertop or in a fermentation chamber, along with thick walls that stand up to repeated use, cleaning, and sanitizing cycles. Its wide mouth opening simplifies pitching ingredients and cleaning between batches, while the tri-clamp-style fittings common across the FermZilla ecosystem make it easy to attach additional accessories as a brewer's setup evolves. Whether used for beer, cider, mead, or wine, this fermenter is designed to reduce oxygen exposure, protect flavor integrity, and give home producers a reliable, repeatable way to ferment, carbonate, and serve beverages with far greater precision than traditional bucket or carboy setups.
