I spend a fair amount of time walking around hardware stores and home centers looking at Weber grills. When I open the lid of many display grills, I see something like this:
This Weber Genesis features cast iron cooking grates. The grate on the left has the narrow, pointed side facing up; the grate on the right has the wide, flat side facing up.
Which orientation is correct?
The grate on the right is in the correct orientation. The wide, flat side of the grate should face up for maximum contact with food and for the best grill marks.
It’s easy to install grates in the wrong orientation when assembling a new Weber grill or when replacing porcelain enameled steel grates with cast-iron grates. But you won’t make this mistake because now you know what’s up!
