What you get with the FastFerment 7.9 Gallon Conical Fermenter
The FastFerment Conical Fermenter is a purpose-built vessel for home brewers and winemakers who want cleaner results without the hassle of siphoning or racking between carboys. Made from food-grade, BPA-free flexible plastic, the conical shape is the real innovation here, borrowed straight from commercial brewery design and scaled down for kitchen or garage use. As fermentation progresses, trub, dead yeast, and other sediment naturally settle into the cone-shaped bottom rather than clinging to the sides or pooling at the base of a flat-bottomed bucket, which means the beer or wine sitting above stays noticeably clearer throughout the process.
What sets the FastFerment apart in practical, everyday use is its built-in valve system at the bottom of the cone. Home brewers can simply open the valve and dump the collected yeast and sediment without disturbing the batch above, then later draw off a clean, finished product straight from a spigot near the top without ever needing to lift the fermenter or insert a siphon tube. This two-valve design dramatically cuts down on oxidation risk and contamination, two of the most common culprits behind off-flavors in homemade beer, cider, mead, and wine. The collection ball at the bottom detaches for easy cleaning and even doubles as a way to harvest yeast for reuse in future batches, appealing to brewers who like to repitch rather than buy fresh yeast every time.
Built for durability and ease of use, the FastFerment holds a standard batch size—typically around 7.9 gallons in its most popular configuration—and includes a stand for stability, given its flexible plastic construction and tall conical profile. The transparent walls allow brewers to visually monitor fermentation activity without opening the lid, reducing the temptation to peek and introduce contaminants. Its flat-pack, collapsible design when not filled with liquid also makes it easier to store between brewing sessions than rigid carboys or stainless conicals of similar capacity, making it a popular middle-ground choice for home brewers who want professional-style clarity and convenience without investing in expensive stainless steel equipment.

Pros & cons
+What we like
- Easy to harvest and reuse yeast without opening fermenter
- Clear visual progress tracking through semi-translucent walls
- Simplifies transfer of beer or wine with no siphoning required
- Durable, lightweight material resists cracking better than glass carboys
- Quick disassembly for thorough cleaning
−Watch out for
- Plastic can retain odors or scratches over time if not cleaned promptly
- Collection ball valve can clog with thick trub or hop debris
- Stand assembly feels less sturdy than advertised
- Higher price point compared to traditional bucket fermenters
Should you buy it?
The FastFerment Conical Fermenter is a solid upgrade for home brewers and winemakers who want cleaner transfers, easier yeast harvesting, and less sediment contamination without investing in an expensive stainless conical. It's not flawless—valve clogging and stand stability are minor annoyances—but for the price, it delivers professional-style conical fermentation to hobbyists.
