8 Best Brew Kettles for Homebrewing

By Matt Giovanisci •  Updated: 01/23/19 •  15 min read  •  Gear

Whether you’re an extract brewer or prefer all-grain brewing, your brew kettle is where the boil happens, and the magical transition from wort into beer begins. The best brew kettle for your needs depends on your brew style and budget. It’s an investment that, with care, will see you through years of brewing, either as your main boiler or as an accessory when you level up.

For our money, the best brew kettle is one that’s versatile, durable, and reliable. Choosing one that fits your brewing setup and beer crafting ambitions is the first step in boiling a beer you’ll be proud to call your own.

Best Brew Kettles for Homebrewing

Brew Kettle Essentials

Like just about every other piece of homebrewing equipment you’ll own, brew kettles are available in a wide range of both prices and fanciness. Top of the line or nuts-and-bolts basic, every brew kettle worth considering features a few essential components.

A Test of Mettle (and Metal)

The most easily recognized trait shared by all the best brew kettles is their material: metal. We’re not ruling out the possibility of futuristic space-age plastic taking the lead one day, but for now, stainless steel and aluminum are top of the heap.

Stainless steel, specifically food-grade 304 stainless steel, is durable, corrosion-resistant, and relatively lightweight. It’s basically inert, so it also keeps its good looks over the years.

Aluminum is not quite as durable as stainless steel, but it weighs less and conducts heat more efficiently. The real drawback to aluminum brew kettles is the metal’s reactivity.

Aluminum reacts with caustic cleaning products, both acids and alkalis, as well as plain old oxygen. It will discolor over time. It can pit, crack, or even produce potentially dangerous gases if it comes into contact with the wrong chemicals. It might also leach into the wort during boiling without proper precautions.

You can create a patina inside an aluminum brew kettle by boiling a little water in it before use. A good pre-boil creates a compound known as alumina (aluminum oxide), which will keep the metal from reacting with the air. It will also help keep it out of your wort, since most recipes aren’t acidic enough to destroy the alumina layer and expose the raw aluminum.

Replenishing your aluminum brew kettle’s patina every time you boil will not only give you peace of mind, but keep unwanted flavors out of your brew.

To conquer the weaknesses of stainless steel and aluminum while taking advantage of their strengths, choose a stainless steel brew kettle with a tri-clad bottom. The “tri” refers to the three layers used. A layer of aluminum is sandwiched between two layers of steel to boost durability, remove reactivity, and improve conductivity.

Brew Kettle Size Matters

If you’re devoted to extracts and small batch brewing, forking over the dough for a kettle the size of a water tower just doesn’t make sense. On the other hand, if you’re all about that brew in a bag (BIAB) life, then your ma’s old soup pot probably isn’t the best brew kettle for you.

Think about the homebrewing adventures you’re likely to pursue, and size your brew kettle accordingly.

5-gallon (13-liter) Batch (Extract Brewing): An 8-gallon (30 L) kettle should give you plenty of room for a full boil, with enough space to minimize boil-overs.

5-gallon (13-liter) Batch (All Grain Brewing): If you’re going all-grain, you need more space to accommodate your grain bill. All grain wort tends to foam more than extract wort, so a 10-gallon (38 L) brew kettle should do the trick. And if you decide you want to do a batch of extract brew every now and then, you’ll have more than enough room.

5-gallon (13-liter) Batch (BIAB method): Forget the teapot. Big brews need big kettles, and there’s not a mash tun in sight. Since you’ll be heating your grains with enough water to cover not only your boil but your mash and sparge, a 15-gallon (57 L) kettle is for you.

Don’t worry if you think you might experiment with smaller batches at some point. A large brew kettle might seem like overkill for a 5-gallon batch, but the flexibility and extra headspace will pay for themselves. But you can always keep a 5 gallon (19 L) kettle on hand as well.

Tall or Small?

Like giraffes or Paul Bunyan cosplayers, brew kettles work best when they’re tall. High sides reduce evaporation loss, and help prevent boil-overs. Brew kettles are generally designed with a height-to-diameter ratio of 1.2:1.

A short kettle isn’t a death sentence for your beer. But a tall kettle that also has the capacity to handle your preferred brewing style will help you avoid messy boil-overs and keep your wort in your beer instead of the air.

Turn Up the Volume (Markings)

The final essential feature of the best brew kettles is built-in volume markings. Sure, you could measure how much wort you’ve got with a yardstick and some high school geometry. But why drag math into your brew day when you can get answers at a glance?

Brew kettles generally have volume indicators etched into the metal, in both gallons and liters. Quart markings, while less common, are nice if your recipes are built around that unit.

Beyond the Basics: Brew Kettle Upgrades

While not essential, a handful of features make brewing just a bit more convenient.

Ball Valves Make Life Easier

Using a siphon to draw off hot wort is a time-tested homebrewing tradition, and we’d never knock it. But when we picture the best brew kettle we can imagine, it definitely has a ball valve. They make transporting wort faster, safer, and much easier. We’re not fans of wrestling a huge kettle full of hot wort, especially with large batches, and we’re pretty sure you aren’t, either.

One important thing to consider when you’re looking at a brew kettle with a ball valve is whether you can use a welded or weldless fitting. It’s largely a matter of preference, but keep in mind that weldless fittings use gaskets to form a seal, making leaks a potential issue. Most modern ball valves are designed to minimize leaks, but it is something to think about if you’re not a fan of mopping.

Welded valves and ports, by comparison, are basically leak-proof (famous last words), but can’t be removed. If something goes south, you might end up having to replace your whole brew kettle instead of just your valve or port. A leak, after all, can generally be repaired with a little plumber’s tape.

It’s Gettin’ Hot in Here: Thermometers

Along with the volume of your wort, knowing its temperature is part of a successful boil. An analog dial thermometer is generally installed in the bottom third of the brew kettle. This lets the thermometer read the internal temperature of the wort, but keeps it far enough away from the heat source to avoid skewing the reading.

Built-in thermometers are especially useful if you’re planning to use your brew kettle as a hot liquor tank for your all grain brewing setup. You can heat your strike water or sparge water to the proper temperature without the need for a separate thermometer.

NOTE: If you’re using a wort chiller to cool your wort and want to use a kettle with a built-in thermometer, be sure the probe from the thermometer won’t tangle in your wort chiller. If you’d rather skip the immersion chiller, you can use a counterflow chiller or plate chiller instead.

Get Every Last Drop with Dip Tubes

Also known as pickup tubes, these slender hoses attach to the back of the ball valve or spigot assembly inside your brew kettle. It’s designed to help you pull as much wort as possible while still leaving the trub, aka the sludge of leftover hops, fats, and proteins at the bottom of the brew kettle, behind.

You could, of course, use a siphon, but dip tubes make it easy to harvest maximum wort with minimal tipping or jostling. They’re especially handy if you’re brewing up a big batch or have a large, heavy brew kettle. Dip tubes are usually positioned to either the side of the brew kettle, or the center.

If you’re handy with a stir paddle and whirlpool your wort, the side pickup is probably your best bet. Keeping the uptake close to the side helps you avoid siphoning off gunk from the hot or cold break, as well as excess hop residue, since those materials will be concentrated in the center of the kettle.

On the other hand, if you have a more upscale brew kettle with a false bottom or hops screen, you might prefer a brew kettle with a centered dip tube. Positioned below the screen or false bottom, the tub uptake can pull your filtered wort from the center of the kettle without fear of contamination.

Depending on the ingredients you use, the occasional tidbit may still slip through even the best screen or filter. You can reduce the chance of contamination by adding an extra filter to the tube, using a hop spider, and keeping your hops whole instead of using pellets.

Induction-Ready Kettles Bring the Heat—Fast

If fire is a little too Stone Age for your setup, you might keep an eye out for an induction-capable brew kettle. Induction heating is faster, more efficient, and more accurate compared to old-school conduction heating.

You can heat a lot of wort fast, and maintain it at an even temperature. Induction is the way to go for batches too big for your range.

Get a Proper Handle on Your Brew Kettle

If you boil over a flame, heat-resistant brewing gloves are probably already part of your homebrewing toolkit.

But if you’re using an electric burner to heat your wort, get a kettle with silicone coating on the handles to help keep things cool while you move or lift your kettle—even if you forget your mitts.

Extra Goodies for Your Brew Kettle

Like cars or watches or the enormously fancy boats of the superrich, the very best brew kettles come with extras you won’t find on your basic stovetop boiler.

Info at a Glance with Sight Gauges

More accurate than interior volume markings, a sight gauge or sight glass tells you the volume in your brew kettle via an external display. Some models also incorporate a thermometer, so you can get the temperature of your brew at the same time.

If you don’t mind cleaning an extra gadget and want maximum convenience and accuracy, this add-on could be an essential part of your best brew kettle.

Dam the Trub-pedoes! Full Speed Ahead!

Also known as a trub blocker, a trub dam is a small piece of metal welded to the bottom of the brew kettle in front of the valve or dip tube. If you whirlpool your wort before draining, a trub dam helps prevent hops and break material from escaping the center and slipping into your fermentor.

Hop (Screen) Along, Little Worties

Upscale brew kettles may feature this gadget. Like a trub dam, a hop screen is designed to keep trub from hitching a ride with your wort. Depending on the make and model, it might also be called a kettle strainer.

NOTE: Because it can clog, snag, or keep you from whirlpooling effectively, keep in mind your brew style, your preferred ingredients, and whether or not you want to use a wort chiller when shopping for a hop screen.

Keep Your Beer Truly Clear with a False Bottom

Fans of espionage and pirate tales will appreciate this gadget. A perforated metal disk, a false bottom isn’t designed to hide microfiche from foreign agents or conceal hidden treasure. But it does allow your wort to flow into the bottom of the brew kettle while holding solids on top.

If your kettle is also your mash tun, then this gadget can be a lifesaver and will definitely be on the list of essentials. Just keep an eye out for potential clogs, and don’t try to stash your laser-cutter watch in there while you’re brewing, 007.

Knowing which features best fit your brew style makes finding the best brew kettle for you a lot easier.
