All the items you need come standard, installed, and ready to use:
  • Heavy gauge, 304 single piece, deep drawn, weld-free American made construction* with 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. The 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 brush finish hides finger-prints and water stains to keep your kettle looking great. Interior finish is smooth for easy cleaning.
  • High-impact glass-filled nylon handles are extremely durable, high temperature resistant, comfortable, and cool to the touch.
  • Open lip on the top of the kettle won't trap water when cleaning and drip leaving water stains.
  • Blichmann Engineering™ was the innovator of the 1.2 height to diameter ratio.
  • Includes adjustable viewing angle BrewMometer™ with patented brewing dial face - or upgrade to Blichmann's interactive wireless BrewVision® thermometer.
  • 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.
  • Blichmann's Patented stepped ledge on the bottom of the 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 fermentor.

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 rimming the flow a little tricky.

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 Tanks: We 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)

Review Comments: I have 20gal pots for HLT and MLT and a 15gal for boil kettle. Wow. I had a bayou classic used for biab previously and these Blichmann G2s are stunning in comparison. The factory punched holes are perfect, and sight glass was accurate out of the box even when all elements, false bottom, whirlpools, etc. were installed. The linear valves are amazing, very easy to dial in flow rates, and a breeze to clean and dry. Very high quality, and worth the price for a purpose built kettle.

Review Comments: Love this kettle and so glad I got the factory to punch the whirlpool port. I brew BIAB with the Brew Bag and get plenty of heat dispersion throughout the kettle during mash by running the whirlpool and no problems with the bag touching the coils. Coupled with the Brew Commander and the Riptide pump, I've got just the system I wanted. Thanks Dave !
