From subtle, but essential features like the handle orientation for easier carrying, cool touch grips, and a lid handle that conveniently rests on the brew kettle or anywhere in the brewery, we design with the brewer in mind.

If you choose a BoilerMaker Surface™Brew Kettle, there isn’t a need for a BoilCoil™ immersion heater or HERMS Coil in your system.  Learn more below, as this brew kettle can easily turn into a family heirloom and the showpiece of your brewery.

Lifetime Warranty BoilerMaker™ G2 Brew Kettle BoilerMaker Surface™ Brew Kettle Robotically welded 1.5″ Tri-Clamp ports Patent pending G2 linear flow valve allows you to easily fine-tune your flow rate for sparging, lautering, and chilling, increasing the repeatability of your system. The built-in 90-degree outlet can be oriented at any angle to make hose routing simple and kink-free. Eliminate those extra elbows and other fittings on the valve for clean and simple routing. Unlike other valves, the new G2 valve disassembles in seconds for a quick cleaning! The cool-touch silicone grip makes handling under fire easy, and the silicone material handles temps to 600° F so it won’t melt as vinyl grips on ball valves do. The G2 linear flow valve is one of the many features tailored specifically for brewers. See the graph below for more details! This valve is a customer favorite! We’ve also moved to a sleek brush finish to hide fingerprints and water stains, keeping your brew kettle looking impeccable for years to come. Plus the interior finish is silky smooth for easy cleaning. High-impact glass-filled nylon handles are extremely durable, high temperature resistant, comfortable, and cool to the touch. We’ve even thought of the little touches like changing to an open lip on the top of the brew kettle that won’t trap water when cleaning and any drips leaving water stains. Blichmann Engineering™ was the innovator of the 1.2 height-to-diameter ratio, not the imitator! All of our brew kettles perform consistently and flawlessly with brewers’ needs at the forefront. Includes adjustable viewing angle BrewMometer™ with our unique patented brewing dial face – the ultimate in brewing convenience! Standard heavy-duty borosilicate glass level gauge never clouds or scratches. Features rugged stainless steel guard with engraved volume graduations in gallon and liter, cleaning brush, and clean-out ports. Much easier and more accurate than internal graduations. It will also act as a mash manometer and warn you of impending stuck mashes! Exclusive snap-in dip tube design installs without tools and drains to within 3/8” of the bottom of the kettle! Handle orientation that makes carrying easier and the lid can be stored on the brew kettle handle. Our exclusive Patented stepped ledge on the bottom of the brew kettle supports the mash screen evenly and virtually eliminates sidewall shunting. Optional Patented button louver false bottom is a hybrid of a perforated screen (high efficiency) and a slotted manifold (plug resistance) that gives you the best of both! Optional Patented HopBlocker™ pellet hop filtration system keeps hops and hot break out of your fermenter.

Because of our commitment to continuous product improvement, design details may vary from the photos shown. This graph explains why the flow of the G2 linear flow valve is easier to adjust than a ball valve. Ball valves are an economical and durable choice for on/off applications. But they are not ideal for flow control. A globe valve, like the new G2 linear flow valve, is ideal for applications where flow control is needed in addition to on/off operation. We have added a parabolic shape to the valve stem to make the flow characteristics nearly linear. What does this mean and why is this ideal in this application? Looking at the blue line of the graph below, the G2 valve has a direct relationship between flow and position of the valve (a straight line). Specifically, when the valve is 1/4th (25%) open the flow is 1/4th (25%) of the maximum flow rate. At 1/2 open (50%) it is at half the max flow rate and so on. Therefore feathering the flow for sparging, lautering etc. is very intuitive and easy to control. The ball valve (the red line), on the other hand, has a flow that is not directly proportional to the position of the handle. When the valve is opened 1/4th of the way (25%), it puts out about 1/2 (50%) of its total flow. At half open (50%), it puts out about 3/4 (75%) of its full flow. This makes trimming the flow a little tricky.

*All brew kettles are 100% locally assembled in our Lafayette, Indiana facility.  Our 7.5, 10, 15, and 20-gallon BoilerMaker™ G2 brew kettles are single-piece American-made construction. The 30-gallon and larger sized BoilerMaker™ G2 brew kettles and BoilerMaker Surface™ brew kettles are imported, welded construction made to fit our extremely strict quality requirements.

Crucial to optimal performance of your new BoilerMaker™ Brew Kettle is selecting the size that best fits your needs. Selecting a brew kettle, mash tun, or hot liquor tank that’s too small or too big, can cause frustration and poor performance.

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’ve hit your target gravity, giving you more time to correct the problem. Also, you’ll 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’d select the 20 gallon BoilerMaker™ brew pot as your boil kettle.

Mash Tun Vessels: We recommend filling your mash tun vessel to no more than 80% of capacity. This will allow sufficient space for dough-in of the grains and additions of sparge water and sparge arms, etc. 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’ve designed the BoilerMaker™ brew kettle sizes to seamlessly blend from size to size, so you’ll never need to sacrifice.

Hot Liquor Tanks: We recommend sizing your Hot Liquor Tank (HLT) to the same size as your mash tun to ensure you have plenty of sparge water available on brew day.

Recommended Three Kettle Systems For Typical Batch Sizes (HLT / Mash / Boil)

5 gal batch: 7.5/7.5/10 or for high gravity beers consider a 10 / 10 / 10 10 gal batch: 15 / 15 / 20 15-20 gal batch: 20 / 20 / 30 32 gal batch: 55 / 55 / 55 (recommended) or 30 / 55 / 55 64 gal batch: 100 / 100 / 100 (our 55 gal pot with the 2bbl extension)

We offer a hole plug so that you can install the BrewMometer™ in multiple locations, perfect for multiple batch sizes in one kettle!
