U.S. Solid 2-Pack 6.5 Gallon Plastic Fermenter with Spigot and Airlock Review (2026)
Updated September 20, 2026 · Research-based review
Our verdict
Two of U.S. Solid's 6.5 gallon spigot equipped fermenting buckets sold together, for brewers who want to run two batches at once or keep one as a dedicated bottling bucket. Each ships complete with its own spigot and airlock, good value for a growing setup, but the pair takes up real storage space.

What we liked
- + 2-Pack lets you ferment two batches or use one as a bottling bucket

Trade-offs
- - Two buckets take up a lot of floor space when stored
- - Spigot gaskets should be checked for leaks before each use
What comes in the pack
According to the manufacturer's own product page, this listing includes two complete 6.5 gallon fermenting buckets, each with its own screw-top lid, an integrated spigot with a 0.374 inch outer diameter, a three piece transparent airlock, and a rubber plug, plus an opener. That means both buckets are fully equipped on their own rather than one being a bare bucket and the other supplying shared accessories, so either one can be used as a standalone fermenter without needing parts from the other. The manufacturer lists the material as food grade, BPA free polypropylene, the same construction used in the single bucket version of this product.
Capacity and build
Each bucket in the pack holds 6.5 gallons and measures about 12 by 12 by 18 inches per the manufacturer's listing, with the pair weighing roughly 2.87 lbs total for the empty buckets and fittings. That is the same capacity and build as U.S. Solid's single bucket fermenter, just doubled, so brewers already familiar with the single version know exactly what they are getting in terms of quality and dimensions. The 6.5 gallon size on each bucket gives useful headspace over a 5 gallon batch, reducing the risk of a vigorous fermentation pushing krausen out through the airlock.
Why buy two at once
Having two complete fermenters opens up a few practical options that a single bucket does not, such as running two different beers at the same time, starting a second batch before the first has finished conditioning, or dedicating one bucket specifically to bottling while the other stays in service as a primary fermenter. For brewers who are scaling up from occasional to more frequent brewing, or who want a backup on hand in case a lid or spigot needs replacing, buying the pair together is usually more convenient and often better value than buying two single buckets separately over time.
Storage space and cleaning
The obvious trade-off of owning two full size 6.5 gallon buckets is that they take up roughly twice the floor or shelf space of a single fermenter when not actively brewing, which matters in a smaller kitchen, closet, or garage setup. Both spigots also need the same careful attention as the single bucket version, meaning they should be disassembled and sanitized between uses rather than just rinsed externally, since a neglected spigot is a common source of contamination in bucket fermenters. Brewers who go this route should plan storage space for two buckets before deciding a two pack is the right choice for their setup.
Who it suits
This two pack suits brewers who are ready to run more than one batch at a time, want a dedicated bottling bucket separate from their primary fermenter, or simply want a spare on hand without paying for two separate single unit purchases. It is less necessary for a brewer just starting out with occasional single batches, where one bucket is plenty and the extra unit would mostly sit empty and take up space. For anyone already committed to bucket fermentation and looking to expand capacity, this pack offers the same reliable spigot and airlock setup as the single version at a reasonable combined price overall.
Frequently asked questions
Does each bucket in the pack come with its own spigot and airlock?
Yes, the manufacturer lists each of the two buckets as complete with its own spigot, airlock, lid, and rubber plug, so both can be used independently.
What size is each fermenter in the pack?
Each bucket holds 6.5 gallons and measures roughly 12 by 12 by 18 inches according to the manufacturer's listing.
Why would I need two fermenters instead of one?
Two fermenters let you run separate batches at the same time, start a new batch before the first is finished conditioning, or dedicate one bucket to bottling while the other stays in use.
Do both spigots need regular cleaning?
Yes, each spigot should be taken apart and sanitized between batches, the same as with the single bucket version, to avoid contamination.
