Sizing Guide

Crucial to optimal performance of your new BoilerMaker™ brew kettle is selecting the size that best fits your brewing needs. Poor size selection can lead to frustration and poor performance. Below are recommendations to optimize your BoilerMaker’s™ performance as a brew kettle, mash tun or hot liquor tank.

Boil Kettles: We recommend always doing a full wort boil, as do most brewing texts and advanced brewers. This minimizes the addition of top-up water to compensate for boil-off, and starting with the volume called for in your recipe will let you know early in the process if you have hit your target gravity, giving you more time to correct the problem. Also, you will get more consistent hop utilization by sticking to the recipe volumes, as utilization changes significantly with specific wort gravity. Last, but certainly not least, is boil-over prevention. Having enough head space will keep this irritating problem at bay.

We recommend a boil kettle approximately 2 times the size of the finished batch size. Although this may seem a bit much, a 10 gallon batch will typically start with a 13 to 14 gallon pre-boil once you compensate for cooling contraction, transfer losses, and boil-off. This will allow for a reasonable head space to reduce boil-over problems. For example, if you're a 10 gallon batch brewer, you should select the 20 gallon BoilerMaker™ brew kettle as your boil kettle.

Mash Vessels: We recommend filling your mash vessel to no more than 75% of capacity. This will allow sufficient space for dough-in and additions of sparge water and sparge arms. The chart below includes various water-to-grist ratios to assist you in your selection. The green column is our recommended water-to-grist ratio. Minimum volumes are to ensure that the thermometer probe is adequately submerged and also that you have an adequate grain bed depth for proper wort filtration. We have designed the BoilerMaker™ brew kettle sizes to seamlessly blend from size to size, so you'll never need to sacrifice.

Hot Liquor TanksWe recommend sizing your HLT the same size as your mash tun to ensure you have plenty of sparge water available on brew day.

The chart below compares the BoilerMaker™ to several competitors' features. By the time you add up extra costs to properly equip the competition and compare it to the additional features they don't offer, you'll agree the BoilerMaker™ is truly in a class of its own.


Level gauges are not available installed on competitors' products. Some uninstalled gauges are available, ranging from $30 to $70, but you need to drill holes and install them yourself. Most of these are plastic, which clouds and yellows quickly. Because they do not fasten at the top, they are also more prone to damage, Lastly, none is as heavy-duty as the Blichmann Engineering gauge, and none is calibrated with level markings as ours is, leaving that arduous task to you.

Thermometers are optional on competitors' units, have an approximate retail price of $35, and generally come at a fixed viewing angle. Adjustable models retail for $70. Because the face can be moved to any position, it is great for multi-tier stands; you can read the temperature without stooping over or using a stool. Once you use an adjustable-angle thermometer, which is available standard on the BoilerMaker™, you will never go back!

Stepped bottoms are not available on competitive units. The BoilerMaker™ stepped bottom makes a perfect seal to the button louver false bottom, virtually eliminating sidewall shunting and channeling offering the ultimate in plug resistance and efficiency.

The BoilerMaker™ is the only brew kettle on the market designed from a clean sheet of paper solely for brewing. The height-to-diameter ratio is the ideal 1.2 to minimize boil-off and also prevent boil-overs. We have also optimized the sizes to blend seamlessly from hot liquor tanks, mash tuns, and boil kettles to fermentors for the common batch sizes of 5 / 10 / 20 / 1 bbl.

Internal dip / drain tubes are not offered in competing products but are needed to fully drain your pot without tipping (disturbing the sediment) and sucking the hops / trub into the fermentor. Our dip tube's low-profile design stays out of the way of your stir paddle and drains to within 3/8" of the bottom of the kettle.

Why do I need a level gauge on every kettle?

There are several reasons why we feel a level gauge is necessary on every vessel in your brewery.

·  Beer is about 90% water, so knowing how much you're using in each kettle is essential.

·  Consistency from batch to batch is all about repeatability and measurements. Using a level gauge will ensure you're starting with the right amount of water and finishing with the correct amount. These measurements will also let you measure your system efficiency.

·  Using a gauge instead of a bucket reduces errors and saves time.

·  Hot Liquor Tank: Initial fill, water chemistry adjustments.

·  Mash Tun: Initial fill, water adjustment, allows you to monitor static pressure on mash to prevent stuck mashes. When the level in the gauge reaches half the level of the mash, you know you're drawing too fast and may stick your mash well before it actually happens. This is particularly useful for RIMS / HERMS brewers.

·  Boil Kettle: Know when to stop lauter runoff and measure the initial and final fill for efficiency measurements. Knowing your gravity points early on allows you more time to correct any issues.

·  The heat shield provided with your BoilerMaker™ will prevent boiling in the level gauge, allowing very accurate readings.

Do I need a clad bottom?

Clad bottoms are great for cooking viscous foods like spaghetti or gravies, especially on an electric stove. Because these foods don't convect like thinner liquids (such as beer wort), scorching is more likely. With the full rolling boil of a wort boil, and the use of a gas/propane burner, scorching is not an issue, even on the lightest worts. Our research and development team has thoroughly tested the BoilerMaker™ pots on high-BTU burners with very light beers (Koelsch, Pils, etc.) and experienced no discoloration or scorching whatsoever. While the clad bottoms look impressive, they add cost, but no real benefit, to the brewer. Because we designed the BoilerMaker™ from a clean sheet, we added cost only where it added specific benefits to the brewer. The stepped bottom, quality level gauge, adjustable BrewMometer™, and snap-in dip tube are a few examples.

Can I brew multiple batch sizes?

It is possible to brew multiple batch sizes, for example 5 and 10 gallons, with the following sizes. Note that you may need to accept some compromises for the added flexibility, such as adding additional makeup water to your boil kettle, thinner mashes, higher boil-off rates, etc. For doing small mashes in a large pot, it is advised to use a thinner mash. This will help maintain temperatures and also allow the thermometer to read the mash. We do offer a thermometer hole plug so you can locate the thermometer at a lower position for smaller batches and the higher position for bigger batch size.

Here are some suggested options.

5 / 10: 5 gal -> 20 / 10 / 15, 10 gal -> 10 / 15 / 20

10 / 20: 10 gal -> 30 / 15 / 20, 20 gal -> 15 / 20 / 30

20 / 30: 20 gal -> 55 / 20 / 30, 30 gal -> 20 / 30 / 55


Our optional patented HopBlocker™ boil kettle filtration system makes short work of filtering pellet hops and trub out of your brew pot. It snaps right into our BoilerMaker™ pots in seconds and can also be adapted for other manufacturers' pots.

Stepped Bottom

All BoilerMakers™ feature a stepped bottom. Our optional patent-pending button louver false bottom sits on this ledge for a tight seal. During lauter, grain weight pushes it against the ledge, creating an impervious seal to virtually eliminate sidewall shunting and loss of efficiency. You get all of this and an incredibly low foundation of water!
