Le Ratio

80-100 BTU par pouce² de surface. Un barbecue de 450 pulg² à 45 000 BTU = 100 BTU/pulg² (idéal). Plus de BTU n'est pas mieux si la surface est petite — cela produit des points chauds.

Par Ménage

1-2 personnes : 2 brûleurs. Famille : 3 brûleurs. Fêtes : 4-5 brûleurs. Une bouteille de 13 kg à feu fort dure ~10h.

⚡ CalcWolf Insight

The grilling industry has an arms race of ever-higher BTU numbers — but experienced grillers know that heat control matters more than maximum heat. A restaurant-quality steak needs 600-700°F surface temperature for searing, which even a 35,000 BTU grill achieves. The extra 25,000 BTU on expensive grills mostly goes to waste. Spend the savings on better meat instead.
