What size camping kettle do I need?

For a solo hiker brewing one coffee, a 1L kettle (Fire-Maple Antarcti 1L, Kuvik 1.0L) is plenty. Couples and small groups tend to favor 1.2L to 1.5L models, while 2L-plus kettles like the Bulin 2.2L suit larger groups or anyone boiling water for multiple uses at once. Bigger kettles weigh and pack larger, so match capacity to your real party size.
