The Best 15-Gallon Brew Kettles For Homebrewing

Published on

What’s the best size kettle for homebrewing? Well, that depends on a few factors. Usually, for homebrewing, you want your brew kettle to be at least 50% bigger than your final volume in the fermenter. So, for 5-gallon batches, a 7-10 gallon brew kettle is a great bet. For 10-gallon batches, you’re going to want a 15-gallon brew kettle.

Selecting the best brew kettle to meet your needs isn’t an easy decision. Check out our comprehensive article covering the pros and cons of all types of brew kettle features here. If you’re looking for electric brewing, we’ve rounded up the best electric kettles, too.

For a very high-end, professional-style kettle, Ss Brewtech offers top quality and functionality with the Ss Brew kettle. This is the best 15-gallon kettle on the market right now.

It’s made from 304 stainless steel with an aluminum core tri-clad bottom. That means even heating throughout the whole volume of wort. You also don’t have to worry about the risk of scorched wort.

The Ss Brew Kettle has 2 tri-clamp (TC) ports. One with an included 3-piece ball valve with a trub dam pick-up tube. What to do with the other port is up to the brewer. You can add an optional whirlpool arm, thermometer, or even an electric element.

The tri-clamp ports are super useful, especially when brewing big volumes. They seal tight, they’re quick to install and remove, and super easy to clean.

We love the Ss Brew Kettle. It’s really hard to beat, considering the medium price point, exceptional build quality, and range of features.

If you’re looking for a solid, affordable, and functional kettle, the MegaPot 1.2 is a great bet. It’s designed specifically for homebrewing. Fully stainless, 1mm thick walls will last you many, many brews. A 4mm thick tri-clad bottom provides great heat distribution to prevent scorching of your wort.

The kettle has an optional false bottom and thermometer, perfect for using it for BIAB. Volume markings on the inside are a nice touch as well. Inside the kettle, a pickup tube connects to the outlet valve helping get every last drop of wort out of the kettle.

All in all, the MegaPot 1.2 is a great brew kettle. Nothing fancy, but just a workhouse with enough features to keep intermediate to veteran brewers happy.

Edelmetall Brü Premium Brew Kettle 15-Gallon

The Edelmetall Kettle has some of the most unique, fun, and interesting features on this list. For a big kettle, it has great options at a relatively affordable price.

It’s constructed from 304 stainless steel with a 4mm tri-clad bottom. Great heat distribution and built for longevity.

The tangential whirlpool arm can be connected to a pump for an extremely effective whirlpool. That benefits both hop flavor extraction as well as settling the cold break for clearer beer. There’s also a fully-rotating snap-in dip-tube accessory that draws down to within 1/8″ from the bottom of the kettle. This combination of whirlpool and rotating dip tube means only the clearest wort makes it into the fermenter.

We really like the Edelmetall for its unique features, quality, and reasonable price point.

Spike is another top-class homebrewing-specific company offering a range of higher-end equipment. The Spike 15 Gallon Brew Kettle is a really fantastic product.

Spike uses a stepped bottom design in their kettles. Basically, a lower center section of the kettle allows trub and hop matter to settle after chilling. Drained from the side dip tube, you’ll end up with much clearer wort in the fermenter. Especially great since you won’t want to be lifting a 15-gallon kettle to drain out wort.

You can choose between either a “horizontal” or “vertical” coupler configuration:

  • Vertical configuration is the standard homebrew kettle setup. The thermometer coupler is directly above the valve.
  • With the horizontal version, the thermometer port is at the same level as the valve port. That means that the thermometer will always be in contact with liquid, no matter how much volume is in the pot. This is a nice feature if you plan to brew smaller batches in your 15 gallon kettle.

The Spike kettle is built like a tank with 1.2mm thick walls and a 5mm tri-clad bottom. All in 304 stainless steel. On top of that, all of the fittings are weldless. You don’t have to worry about leaks from typical weldless fittings, which really eases the mind when you’re brewing large batches.

Anvil Brew Kettle – 15 Gallon

Anvil Stainless Steel Brew Kettle (15-Gallon)

This rugged kettle is constructed from high quality materials and designed for a lifetime of demanding use.

Anvil makes a solid brew kettle for a reasonable price. Made from 18 gauge, 304 stainless steel, these kettles come standard with a thermometer and 1/2 inch NPT ball valve. The valve includes a dip tube that reaches down to within 3/8 inches of the bottom of the kettle.

For a homebrew-specific kettle, the Anvil is relatively no-frills. It’s just a well-made, stainless kettle that will last you a lifetime. If you’re looking for a functional, economical kettle that can be used for BIAB, a boil kettle, or a HLT, the Anvil kettle is a very solid option.

If you’ve made it this far, you’re a serious homebrewer looking to take your brewing to the next level. Bigger batches mean that people are really starting to like your beer! To make sure the quality of your brews continues to progress, opt for a well-made, feature-rich 15-gallon kettle.
