Scale
Japanese: スケール（秤）（すけーる）
A tool for accurately weighing ingredients. Indispensable for reproducible miso making.
A digital scale weighs ingredients to the gram. In miso making, soybeans, koji, and salt are all managed by weight, making a scale essential.
For home use, 2-5 kg maximum capacity with 0.1-1g resolution works well. Salt in particular — even small errors significantly affect flavor, so 0.1g resolution is preferred. Weight measurement is more accurate and reproducible than volume measures like cups. A tare function conveniently subtracts container weight. If you continue making miso, investing in a reliable scale is worthwhile.
