"You're gonna need a bigger boat"
That was the classic line Brody uttered in Jaws once he saw how large the shark was.
All grain brewing itself is a bit of a giant shark but instead of a boat, you're gonna need a bigger brewing kettle. Of course, malts kit brewings with specialty grains benefit from a kettle too!
Things to consider when buying a brew kettle
- There are several benefits to having a brew kettle (or brew pot) that's large in size. The obvious one is that you can brew more beer! There's also less risk of a boilover or overflow occurring.
- If you want to do small batches of beer, you obviously don't need a massive 15 gallon kettle. However, once you get the taste for brewing, you may just find that 5 gallons just doesn't do it for you anymore, and you want to make 12 gallons - so you'll need that bigger kettle. You can always fry a turkey in it for Thanksgiving too!
- You may want to consider having a built-in thermometer as that can save you some hassle.
- A ball valve is almost essential. Stainless steel ball valves are used on your kettle to allow you to control the flow of your liquids during transfers. If you have the budget for it, we strongly recommend you get a brew pot that features the valve. They give you so much control and are easy to strip down and clean.
- A 'sight glass' which allows you to check the level of wort in your kettle. As the wort evaporates due to the boil, it's handy to keep your eye on the level without having to take the lid off the kettle. If you do not have a sight glass, fear not. Crafty brewers have many tricks up their sleeves and having a wooden rod or spoon with marks for the desired wort levels is one of them.
- Some kettles come with a dip tube or pick up tube as they are known. These devices are used to extract the wort that lies below the ball valve, which makes for a more efficient collection of wort. These are often used with a hops screen which is used to filter out lumps and bumps from the wort.

Bayou Classic 800-416 16 Gallon Stainless Steel 6 Piece Brew Kettle
"This is a quality kettle, and a decent price. I use it in tandem with a standard size keggle for my HLT, and can brew up to 15 gallons at a time if I feel incredibly strong and dedicated (15 gallons of wort weighs a lot). The thermometer works well, and has clear markings for various mash stages, if you do more than a single-step infusion."
"Great brew kettle. Very large with a tri-ply bottom. Have used it twice for brewing in a bag, thus far. Will hold a large grain bill - 16 lbs for me on my last brew. Screen will clog up, but not so much to not allow me to drain into the fermenter. Temp gauge required no calibration upon cross measuring. I did leave the kettle outside for a few days by accident and was pleased to see no signs of rust."
"The kettle held my mash at temp for the full hour, was easy to clean up and easy to transfer the wort to the boil kettle."

"Awesome. Thick bottom. Used to deep fry my 25 pound Thanksgiving turkey. Heated great no burnt crud on the bottom and easy clean up because nothing burned."
"Really good quality! Nice riveted and welded handles, extra thick bottom, strong sides, and is just the right size for a 5 gallon brew. If you're doing a full 5 gal, be careful during the hot break, as the wort level is pretty close to the top. Stand guard at the gas valve! Excellent product, cleans well, and can also do a turkey or a beach boil. Get it!"
"I've brewed with it a few times now and it works great. I think it would be better if it had some volume markings."

"The design of the kettle is fantastic. Great lids, handles, and I love the sight glass. Makes it really easy to clean it.
"Only con is if you plan on using this on gas. My use is electric. The bottom doesn't have a nice thick plate in it, it is just as thick as the sides. This will cause it to heat up more slowly on gas. For the price I would expect it to be included but for me on electric it is actually a plus as it makes it easier to move the kettles around."
Should you buy Aluminium or steel?
Brew kettles come in both metal forms, each having its own benefit.
Aluminum is lighter for example but is less durable than steel kettles.
They also need to be maintained well due to ensure that the oxide layer that forms is not broken. This is because the layer prevents the aluminum from passing off-flavours into the wort or mash.
While aluminum kettles will transfer heat faster than steal, if you have a really good gas burner, this shouldn't really be a concern with your buying decision.
In our realm, we recommend you go for the steel kettle - the only drawback is they are more expensive than aluminum units.
Stainless steel is also fairly easy to clean. The choice is yours, Captain!
What is the best way to clean a brew kettle?
The gunk that is left at the bottom of the kettle is called the trub and it's usually quite manageable to get off. Many brewers like to soak the trub in water with Powdered Brewery Wash (AKA PBW).
Do not use steel wool or anything sharp to clean the unit, use something soft like a non-abrasive sponge or a soft plastic brush. You are trying to avoid putting scratches in the steel!
It's also good to clean your kettle as soon as you can after brewing - this will give the trub less time to harden and should ensure a straightforward cleaning job.
If you have an aluminium kettle, you'll want to avoid anything caustic and stick with ordinary washing detergent.
I personally dispose of the trub on my vegetable garden!
Finally, once you have chosen your kettle and brewed with it, you'll need to keep an eye out for beerstone, which is a calcium based build up which can harbor microorganisms that will ruin your beer.
Brew day safety tips
Once that wort has been boiled, you've now got to cool it down so you can pitch the yeast - but what you've done is heated many gallons of water so hot it can give you a terrible scalding. So be careful!
Ensure your setup is sturdy. Your burner needs to be flat and properly assembled. Your kettle should have handles (ones coated with silicon are perfect) to assist with moving. Even so, you may want to consider using an oven mitt and a waterproof apron.
This is especially so if you are deep frying a Thanksgiving day turkey with oil.
And shoes, wear shoes!
And finally, be wary of any children around your setup. Frankly, we recommend you let the kids stay inside and watch Star Wars while you have the gas going!
