brewing innovation

BoilerMaker™G2

Designed and manufactured in the USA.  We've made the perfect kettle Perfect-er!

The BoilerMakerG2 brew kettles have been completely redesigned from the ground up with world-class American engineering and quality US manufacturing!*  We've made a massive investment in tooling to build the best kettle on the planet right here at home.  Using only the best materials, the BoilerMaker™G2 line of brew kettles is ideal for homebrewing – sacrificing neither features or quality and available in perfect sizes. Bare bones kettles might lure you in with attractive prices. But by the time you add extra equipment you need or want – all standard in the BoilerMaker™G2 – you’ll find our brew kettles are the best value and will be handed down for generations to come! All models carry a limited lifetime warranty and available in Celsius or Fahrenheit models.

*30 gallon and larger kettles imported, but fully assembled with US labor and additional US components.  Lid design on the 30 and 55 gal kettles are traditional design.  See photo gallery for image.

Features

This fresh design reflects the Blichmann Engineering passion for quality, ergonomics, aesthetics, performance, and simplicity — from such innovations as the stepped bottom, patented Button Louver false bottom, patented HopBlocker™, patent pending easy to adjust linear flow valve and snap-in dip tube.  From subtle, but essential features like handle orientation for easier carrying, cool touch grips and a lid handle that can be conveniently rested on the kettle or anywhere in the brewery. 

All the items you need come standard, installed, and ready to use:

  • Heavy gauge, 304 single piece, deep drawn, weld-free American made construction will turn this kettle into a family heirloom*.  We are so impressed with the quality of this kettle that we have given it a limited lifetime warranty!
  • 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 like vinyl grips on ball valves do.  The G2 linear flow valve is one of the many features tailored specifically for homebrewers.  See the graph below for more details! 
  • We've also moved to a sleek brush finish to hide finger-prints and water stains to keep your 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 kettle that won't trap water when cleaning and drip leaving water stains.
  • Blichmann Engineering™ was the innovator of the 1.2 height to diameter ratio not the imitator!  All of our pots perform consistently and flawlessly with homebrewers 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 kettle handle.
  • Stepped bottom on kettle supports mash screen 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 fermentor.

Because of Blichmann Engineering’s™ 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.

 

* 7.5,10,15,20 gal pots are single piece American made construction.  30 gal kettles and larger are imported, welded construction made to our strict quality requirements.  All kettles 100% assembled in our facility in Lafayette, Indiana.

Sizing Guide

Crucial to optimal performance of your new BoilerMaker™ brew pot is selecting the size that best fits your brewing needs. Selecting a brew pot, mash tun, or hot liquor tank (HLT) 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 Vessels: We recommend filling your mash 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 pot 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.

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 BrewMometerin multiple locations, which is great for doing multiple batch sizes on one pot!

G1 Info

G1 Status and Accessory Compatibility

If you wish to purchase a G1 BoilerMaker™ brew kettle to match your system we do have a limited quantity of cosmetic defects kettles that are available at a discount through your retailer and carry our full warranty.  We also have a very limited quantity of 7.5 and 30 gal first-run G1 kettles available.

While the BoilerMaker™G2 has many significant upgrades it does share a lot of backwards compatible features and accessories with the G1 BoilerMaker. However, some changes were necessary to accommodate the US made, deep drawn, single piece construction process.

The HopBlocker™, AutoSparge™, and BrewMometer™ are fully compatible with the G1 and G2 models.

The BrewMometer™ hole has been lowered about 1" on the BoilerMaker™G2 to accomodate smaller batch sizes.

The 7.5, 10, 30, 55, 100 gallon false bottoms are interchangeable between the BoilerMaker™G2 and the G1 BoilerMakers™. 

BoilerMaker™G2 20 gal. false bottom is backward compatible to the G1 BoilerMaker, however the G1 false bottom is slightly smaller in diameter and while it will fit into a BoilerMaker™G2 and work reasonably well, it may pass a bit of grain until the mash bed is set and seals to the stepped bottom.  We wanted the false bottom to fit perfectly and perform flawlessly, so we engineered a G2 false bottom, backwards compatible to a G1 BoilerMaker™.  If you want to use your existing 20 gal G1 false bottom in a G2 it will work adequately but may not work perfectly.  We recommend the false bottom that fits perfectly if you don't already have a false bottom.  

The G2 and G1 15 gal false bottoms are not interchangeable as the US construction unfortunately necessitated a diameter change (about 1/4") in the new BoilerMaker™G2. We will continue to offer the G1 15 gal false bottom for the indefinite future.

Outside dimensions of the kettles have changed very little and should fit into any system developed for the BoilerMaker™ G1 kettles.  Reference the chart on the data tab for more details.

 

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!

Competition

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.  Always has been, and always will be.

CHART NOTES

Level gauges are available installed on some competitors' products.ranging from $30 to $70. Others use a economy internal etched graduations which are difficult to read during a boil.  Most external gauges are plastic which cloud and yellow quickly. Because they do not fasten at the top, they are also more prone to damage, Lastly, none are as heavy-duty as the Blichmann Engineering gauge, and none are calibrated with level markings as ours is, leaving that arduous task to you.  The external guages dampen out the boil, read accurately, and for mash tuns they can be used to gauge how hard you re drawing on your mash indication to you a pending stuck mash!

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's 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'll never go back!

Stepped bottoms are not available on competitive units. The BoilerMaker™ stepped bottom makes a perfect seal to the mash screen, virtually eliminating sidewall shunting and channeling. Plus, our patented button louver false bottom offers the ultimate in plug resistance and efficiency and has set the standard in performance and ease of cleaning.

The BoilerMaker™ is the only brew pot on the market designed from a clean sheet of paper solely for brewing. The height-to-diameter ratio was developed through extensive research by Blichmann Engineering to the ideal 1.2 height/dia ratio to minimize boil-off and also prevent boil-overs. Others have merely copied out brilliant engineering.  We've 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 / 1bbl.

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 pot!

FAQ

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
