By Caleb MorganUpdated November 2026
A 5 gallon fermenter bucket is the workhorse of most home brewing setups. It holds a standard five-gallon batch of beer, wine, mead or cider with enough headspace to handle active krausen, and it is cheap enough that many brewers keep two or three on hand. The trouble is that buckets vary more than they look. Lid fit, spigot placement, plastic grade and whether a lid includes an airlock grommet all change how easy a brew day is. This guide covers six buckets chosen by how well their specifications match common homebrewing needs, along with the factors that should drive your choice.

Buying Guide
Capacity and headspace
A 5 gallon batch needs room for krausen. Most brewers use a bucket rated 6.5 gallons or larger for five-gallon batches, which leaves roughly one to one and a half gallons of headspace. Smaller buckets can overflow during active fermentation.
Good picks for this: FastRack 2-Pack 6.5 Gallon Fermentation Bucket, Fastrack 6.5 Gallon Fermenting Bucket
Spigot or no spigot
A spigot lets you drain beer without siphoning, which reduces oxygen exposure and splashing. If you bottle from the primary, a spigot is worth considering. Keep it above the trub layer to avoid pulling sediment into bottles.
Good picks for this: FastTrack Fermentation Bucket with Spigot, U.S. Solid 2-Pack Plastic Fermenter
Lid fit and airlock compatibility
Check that the lid has a grommet sized for a standard three-piece airlock. Press the lid down firmly to confirm it sits flush. A loose lid can let in contaminants or fruit flies.
Good picks for this: FastRack 2-Pack 6.5 Gallon Fermentation Bucket, Airtight Seal 5 Gallon Square Fermentation Jar
Shape and storage space
Round buckets are the default, but square jars use shelf space more efficiently. Measure your storage area and check the footprint before buying.
Good picks for this: Airtight Seal 5 Gallon Square Fermentation Jar
Material and food-grade rating
Look for food-grade plastic such as HDPE or polypropylene, and confirm BPA-free labeling where it is stated. Glass is inert and easy to inspect but heavy and fragile. Plastic is lighter and more forgiving to handle.
Good picks for this: Glass Carboy, Fermentation Bucket and Accessories Kit, FastTrack Fermentation Bucket with Spigot
Durability and cleaning
Scratches can harbor bacteria. Inspect buckets for deep gouges and replace them if you find any. Use a no-rinse sanitizer and avoid abrasive pads that scratch the surface.
Good picks for this: Fastrack 6.5 Gallon Fermenting Bucket with Lid, FastRack 2-Pack 6.5 Gallon Fermentation Bucket
Budget and number of fermenters
If you plan to brew overlapping batches, buying two buckets at once is often more practical than one. Consider whether you need a spigot on both.

FAQ
Can I use a 5 gallon bucket for a 5 gallon batch?
You can, but it is risky. A bucket rated exactly 5 gallons leaves no headspace for active fermentation. Most brewers choose 6.5 gallon buckets for five-gallon batches.
Is a spigot necessary?
No. Siphoning works well and many brewers never use a spigot. A spigot is a convenience for bottling directly from the fermenter.
Are plastic buckets safe for fermentation?
Food-grade plastics such as HDPE are widely used for home fermentation. Check labels for food-grade and BPA-free claims. If you have specific health concerns, consult a qualified professional.
How do I clean a fermentation bucket?
Rinse out residue, wash with warm water and a mild cleaner, then sanitize with a no-rinse sanitizer before each batch. Replace buckets with deep scratches.
Do I need an airlock?
An airlock lets CO2 escape while keeping air and contaminants out. Most brewers use one, though a sealed lid with a blow-off tube is another option during vigorous fermentation.
Glass or plastic?
Glass lets you see fermentation and is inert, but it is heavy and breakable. Plastic buckets are lighter and easier to handle. Many brewers keep both.
Conclusion
For most brewers, the FastRack 2-Pack offers spare capacity and grommeted lids. Choose the FastTrack with spigot for bottling from the fermenter, the Airtight Seal square jar for limited space, and the U.S. Solid two-pack for a budget-friendly second fermenter. The glass kit suits beginners who want everything in one order. Match the bucket to your batch size, bottling method and storage space, and you will avoid most common brew-day problems.
