Blichmann Electric Boilermaker G2 Brew Kettle, 240 volts, fahreheit.

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 possible issues. 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 like a large volume, a typical 10 gallon batch will start with a 13 to 14 gallons pre-boil volume. 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™G2 brew kettle.
