Thank you for choosing SUBITO COTTO!
Subito Cotto is a real small and light wood-burning oven, ideal for residential use, with a roof and dome made entirely of high
quality refractory concrete. Available in combined wood-gas version.
As in traditional wood-burning ovens, once the cooking temperature is reached, the oven maintains this temperature for a long
time, even after the fire or flame has gone out. Immediately cooked it is ideal for cooking Italian pizza, but it is also suitable for
cooking other foods such as bread, meat, fish, vegetables
and sweets.
All Subito Cotto models are ready to use. They must not be assembled, insulated or finished. They are lightweight and can be
transported and used even in small spaces such as terraces, kitchens or gardens. Their consumption of wood and gas is also
very low. Both wood and gas versions reach a cooking temperature of:
•450 °C (850 °F) in just 30 minutes for IMMEDIATELY COOKED 60
•450 °C (850 °F) in just 40 minutes for IMMEDIATELY COOKED 80
•450 °C (850 °F) in just 55 minutes for IMMEDIATELY COOKED 100
•450 °C (850 °F) in just 30 minutes for SUBITO COTTO MINI
The gas version of the oven is equipped with a Made in Italy burner and can be used with propane, LPG or methane.
