If you are a grilling enthusiast and have been looking for the right new gas grill to invest in, you have most likely already heard of the Weber brand. While Weber is a household name internationally when it comes to grilling, you must have thought about the Weber Spirit vs Genesis debate and wondered which model would be the right one for your needs.

In this guide, we take a closer look at the Weber Spirit and Genesis lines of gas grills and analyze their pros and cons and unique features to help make your decisions easier.

Weber Spirit vs Genesis Overview

Weber has been in business for a very long time since its inception in 1952 when founder George Stephen created the kettle grill. The Genesis line of gas grills started in 1985 while the early ’90s brought about the start of the Spirit line. Since then, both these product lines have seen several great advancements that have been acknowledged as some of the best gas grills that money can buy.

Design and Manufacturing

While Weber products have for long, carried the moniker “Made in the USA”, there has been some controversy about the way they have handled their product manufacturing and assembly in the past. A discovery that many Weber grills used components and parts manufactured in Taiwan and China led to a class-action lawsuit in 2011 about the use of the “Made in the USA” label.

Weber settled the case and changed the product label to “Made in the USA, incorporating globally sourced component parts”. Indeed, the products have always been designed and developed in the USA and continue to be that way, incorporating rigorous testing and a generous warranty to substantiate their belief in the quality of their products.

However, except for the Weber Smokefire, all other Weber models are no longer made in the USA entirely. While several models are assembled locally, both the Spirit and Genesis lines are now made and assembled entirely in Taiwan or China.

Important Similarities and Differences

While the Spirit and Genesis series of grills are some of the most popular Weber products, there are certain similarities and differences that you need to be aware of. The Spirit series of grills features more barebones, simple, and value-oriented products that can be a great choice for beginner grillers. The Genesis line, on the other hand, has more premium offerings that bundle in extra features and better quality and durability. If you are looking to use your grill more often or consider yourself a lifestyle griller, a Genesis model might be for you.

The Spirit and Genesis series of grills now feature modern products that have had features and functionalities added to them over time. Both lines now feature compatibility with Weber’s iGrill technology and feature the much-improved GS4 grilling system. Both lines also come with the same extensive 10-year guarantee that covers every component part of the grill. On the flip side, you might expect Spirit models to be available at lower price points. 

The Genesis models also have higher BTU numbers owing to more burners. Some Genesis models also come with optional extras like an enclosed cart or a sear station.

The GS4 Grilling System

The updated GS4 grilling system is one of the main features of both the Spirit and Genesis lines. This upgrade aims to improve grilling performance, allow for better management of grease and flare-ups, and promise better-tasting food overall.

The upgrades include:

  • A better, more reliable ignition process that incorporates improved electrodes, a protected ignition module, stronger wire coatings, and easily replaceable batteries.
  • Upgraded burner tubes that allow even dispersal of heat across the cooking surface. This is courtesy of the reversible and tapered nature of the tubes, which correct issues with uneven heating that Weber grills have sometimes suffered from previously.
  • The use of triangular bars below the cooking surface that deflect grease off the burner, thereby reducing flare-ups. At the same time, the grease drips can sizzle and create smoke that can impart additional flavor to the food.
  • A dedicated collection pan for catching grease droplets that can be easy to clean after cooking.

iGrill Technology

A much-needed feature that can be found in both the Spirit and Genesis lines is the iGrill technology – a Bluetooth meat thermometer that can be used to remotely monitor the temperature of the meat while cooking. The thermometer mounts on the side of the grill and can send temperature data to your smartphone via an app. It can be used to monitor the internal temperatures of four different pieces of meat while cooking and makes it easy for users to be able to step away from the grill once the cooking process starts.

The Weber Genesis vs Weber Spirit

One of the smaller models, the Spirit E-310 can still be enough to serve up to seven people. Using three stainless steel burners, this workhorse can provide an output of 30,000 BTU over 529 square inches of total cooking area, separated between the main cooking area and an additional warming rack. The fuel tank is mounted outside with a large, easy-to-read fuel gauge.

The sturdy construction makes use of an open cart design that provides a lot of storage space under the unit. Mobility is provided thanks to a couple of all-weather wheels. The grill also has six hooks integrated into the main unit that can make it easy to organize your tools. A workspace to prepare your meats is provided in the form of two side tables of which the left one can be folded down.

The cast-iron grates are porcelain-enameled for better heat transfer and service life. Some of them are also reversible, providing you a thin side and a wide side. Large cuts and steaks can cook well on the wide side while the thin side can be used for more delicate cuts and fish.

The units come with the standard 10-year warranty.
