Guide Review - Weber Genesis S-320

Weber builds grills that are among the most recommended in the world.

Their wide availability makes them very popular as does their consistently high quality of manufacturing. This Weber grill is an attractive unit of stainless steel and painted black. The lid is a heavy dual layer stainless steel piece with a cast aluminum fire box. The frame is welded steel and very strong.

Welded steel is much better than the riveted or bolt frames on many lower quality grills.

Apart from the looks, the Weber burner system provides good heat distribution that eliminates hot and cold spots. The three burner configuration gives you the ability to grill indirectly or to have a hot sear zone while having a cooler grilling area. Control on this grill is very good because of its highly adjustable valves.

The Genesis S-320 offers 42,000 BTUs from its three burners under a primary cooking area of 507 square inches. While this is a little low for a grill of this size the efficient design generates more heat with less fuel than many other grills. This unit should reach maximum temperature in less than 10 minutes and can easily sear. This unit also comes with a 12,000 BTU side burner.

The biggest gripe with this grill is the almost complete lack of work space. With the control valves consuming most of the right side table this leaves you with only the left side to work with. There's just enough space to put down a normal sized plate and nothing else. Flip up tables (like older models) would certainly be nice.

While you pay for the Weber name, they are the only company that will give you 24/7 support 364 days a year.

They also have a great reputation for service. This grill is also available in natural gas.

Don't need the side burner? Try the Weber Genesis S-310. Need more space? Try the 4-burner Weber Summit E-420
