On average, in winter you will need 0.2 litres (8 oz) of gas per person per day to melt snow. For gas stoves, we recommend 60 grams (70/30 butane/propane) of gas per person daily in summer, and 120 grams or more per person daily in winter. These are approximate figures, not taking into account weather conditions. We recommend taking a small reserve to make your trip more pleasant in winter.
