Market guide
Size the batch, room and circuit
Let the finished beer and the brewing space choose the equipment classFinished batch volume is not the vessel's headline capacity. Grain, mash water, boil expansion, losses, chilling and transfer all consume room, while the electrical and cleaning plan determine where the system can operate safely.
Recipe
Plan the hardest regular batch
Record finished volume, original gravity, grain mass, boil time, hop load and any small or oversized batches. Basket and vessel limits can arrive before the nominal volume.
- Headspace
- Keep safe room for foam and boil behavior rather than filling to the rim.
- Range
- Check both minimum and maximum batch behavior if the system must brew several sizes.
Power
Verify the installed circuit
Match voltage, amperage, plug, frequency and GFCI protection to the exact regional model. A high-power wet process should not be improvised with an undersized extension or adapter.
- Owner
- Have qualified electrical work completed before the equipment arrives.
- Load
- Account for other devices on the circuit and any simultaneous heater and pump draw.
Room
Make steam, water and drainage explicit
Boiling adds heat and moisture. The room needs ventilation, a stable surface, water supply, spill control, a drain or safe waste-water path and room to lift or remove grain without standing under hot liquid.
- Clearance
- Measure the full height needed to raise the basket or service the system.
- Transfer
- Choose pump and hose routes that avoid carrying a full vessel of hot wort.
