What is a Conical Fermenter?
A conical fermenter, also sometimes referred to as a unitank fermenter, is a cylindrical vessel with a cone-shaped bottom. This distinctive design plays a crucial role in yeast management and optimizes the fermentation process for brewers of all levels.
How Does a Conical Fermenter Work?
During fermentation, yeast converts wort (unfermented beer) into beer by consuming sugars and producing alcohol and carbon dioxide. As yeast performs its magic, it also generates spent yeast cells and hop particles that sink to the bottom of the fermenter due to gravity.
In a traditional cylindrical fermenter, this sediment disperses throughout the beer, making it challenging to siphon off clear beer for bottling or kegging. This is where the magic of the conical fermenter comes in!
The cone-shaped bottom of a conical fermenter acts as a collection point for yeast sediment and hop particles. This facilitates a cleaner separation between the beer and the sediment, allowing you to easily extract crystal-clear beer for bottling or kegging without disturbing the settled yeast.
Features of Conical Fermenters
Here’s a closer look at some of the key features that make conical fermenters a favorite among homebrewers:
- Clearer Beer: The conical design promotes superior yeast and sediment separation, resulting in crystal-clear beer that looks professional and polished.
- Easier Transfer: The conical bottom concentrates the sediment in a central location, allowing for easier siphoning of yeast-free beer without the risk of transferring unwanted sediment.
- Yeast Harvesting: Many conical fermenters come equipped with a dump valve located at the lowest point of the cone. This makes it convenient to harvest healthy yeast for future batches, reducing costs and promoting consistency in your brews.
- Temperature Control: Some conical fermenters are jacketed, meaning they have a double wall that can be filled with glycol or water for precise temperature control. This feature is particularly beneficial for brewing lagers and other styles that require specific fermentation temperatures.
- Multiple Uses: Conical fermenters can be used for fermenting a wide variety of beverages beyond beer, including cider, mead, and wine.
Types of Conical Fermenters
Conical fermenters come in a variety of shapes, sizes, and materials to suit the needs and budget of every homebrewer:
| Type | Material | Pros | Cons |
|---|---|---|---|
| Stainless Steel | High-grade stainless steel | Durable, easy to clean and sanitize, long lifespan | More expensive compared to plastic options |
| PET Plastic | Food-grade PET plastic | Lightweight, affordable, transparent allows for monitoring fermentation process | May be prone to scratches and may not be suitable for high-pressure applications |
| Pressure-Capable Plastic | High-density, pressure-rated PET plastic | Affordable, lightweight, transparent, allows for closed-transfer fermentation and carbonation | May not be as durable as stainless steel |
Choosing the Right Conical Fermenter
Selecting the perfect conical fermenter requires careful consideration of several factors:
Capacity:
- Consider the typical batch size you brew. Conical fermenters range in size from a few gallons up to hundreds of gallons. A good rule of thumb is to choose a fermenter that holds at least 20% more volume than your typical batch size to allow for headspace during fermentation.
Space:
- Measure your available brewing space to ensure the fermenter will fit comfortably. Don’t forget to factor in headspace and clearance for hoses and other equipment.
Material:
- Stainless Steel: The most durable and long-lasting option, offering excellent temperature control and ease of cleaning. However, stainless steel conical fermenters carry a higher price tag.
- PET Plastic: A budget-friendly choice that’s lightweight and transparent, allowing you to visually monitor your fermentation. However, PET plastic may be more prone to scratches and may not be suitable for high-pressure applications.
- Pressure-Capable Plastic: A good compromise between affordability and functionality. These fermenters are lightweight, transparent, and allow for closed-transfer fermentation and carbonation under pressure. They may not be quite as durable as stainless steel but offer greater versatility than standard PET plastic.
Features:
- Jacketing: If precise temperature control is important for your brewing style, consider a jacketed conical fermenter. This feature allows for circulation of glycol or water to maintain consistent fermentation temperatures.
- Dump Valve: A dump valve located at the lowest point of the cone facilitates easy harvesting of yeast for reuse in future batches.
- Accessories: Many conical fermenters can be outfitted with additional accessories such as thermowells, sample ports, and pressure gauges, depending on your needs and preferences.
Cost:
- Conical fermenters range in price depending on size, material, and features. Expect to pay between $150 and $3,000 or more for a high-end jacketed stainless steel fermenter.

FAQ
Q: How much headspace do I need in my conical fermenter?
A: Allow for at least 20% headspace to accommodate foam and carbon dioxide production during fermentation.
Q: Can I use a conical fermenter for fermentation under pressure?
A: The suitability for pressure depends on the material and pressure rating of your conical fermenter. Ensure your fermenter is pressure-rated if you plan to carbonate your beer within the fermenter.
Q: How do I clean a conical fermenter?
A: The cleaning process is similar to cleaning any fermenter. Disassemble all removable parts and wash them thoroughly with warm water and a non-abrasive brewing cleanser. You can use brushes specifically designed for cleaning conical fermenters to reach the narrow cone area. For a more thorough clean, you can fill the fermenter with a cleaning solution and circulate it through the pump (if your fermenter has one) for a designated sanitizing period. Always rinse thoroughly with clean water and sanitize all surfaces before reusing the fermenter.
