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: Blichmann recommends doing a full wort boil. 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.
Blichmann recommends 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: Blichmann recommends 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 on the Data tab includes various water to grist ratios to assist you in your selection. 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. Blichmann designed the BoilerMaker™ brew pot sizes to seamlessly blend from size to size.
Blichmann offers a hole plug so that you can install the TherMometer in multiple locations...great for doing multiple batch sizes in one pot.
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)
Blichmann offers a hole plug so that you can install the BrewMometer™ in multiple locations, which is great for doing multiple batch sizes in one pot.
