Choosing Between Blendtec FourSide and WildSide Jars

Blendtec blender jars are engineered to create a strong vortex that pulls ingredients toward the wingtip blade without requiring a tamper. The FourSide™ jar excels at smaller batches and finer grinding tasks, while the WildSide® jar is suited for larger recipes and high-volume blending applications.

About Blendtec

Tom Dickson developed a more efficient grain mill design in the 1970s when, in cleaning up a spilled batch of grain, he discovered vacuuming the grain cracked the entire kernel. Dickson later invented the In-Counter Blender, a standalone blender flush-mounted and engineered for powerful blending while minimizing countertop clutter.

In 2001, Blendtec introduced the WildSide jar, which featured a fifth side that forced ingredients off the walls and into the path of the blades. Dickson began making appearances on TV and YouTube with the $50-per-video “Will It Blend?” marketing campaign, resulting in millions of views and an increase in sales. Today, Blendtec is an industry leader known for powerful motors, unique jar designs, and no-tamper technology.

Key Strengths:

• Jars are universally compatible with Blendtec blenders
• Different colored WildSide jars help prevent cross contamination
• Square design maximizes blending power

Key Differences Explained

Performance and Reliability

Both jars are constructed of BPA-free copolyester. The FourSide jar features a blunt safety blade and is compatible with all Blendtec commercial blenders; its narrow base makes it suited for processing small servings. With a wide base and a nearly 4-inch-long blade, the WildSide jar features five sides with capacity to blend thicker mixes quickly. Its three corners ease pouring, and the durable construction and blunt blade design support high-speed blending while helping reduce wear during daily use.

Design and Ease of Use

The square shape of both jars improves efficiency by disrupting the circular vortex, pushing ingredients upward before pulling them back toward the blade. Neither jar requires a tamper because the square design redirects ingredients into the blade. Both jars have thick, dull safety blades that pulverize ingredients at high speeds rather than slicing them, while the jars’ markings indicate ounces and cups. The WildSide's fifth side increases blending efficiency and eases larger-capacity processing. A Mini Wildside jar holds 24 ounces while delivering the same quality and efficiency as the larger version.

Maintenance and Durability

Before blending, manually rotate the drive shaft a few times to activate the self-lubricating bearing system. Although both jars are dishwasher safe, temperatures higher than 220 degrees Fahrenheit can degrade the seals and warp the jar over time. BPA-free copolyester construction helps resist shattering, though heavy ice use may cause micro-scratches. With proper care and maintenance, Blendtec jars can last seven years.

Price and Value

Blendtec jars offer value from efficient blending and durable construction. The square design supports everything from grinding frozen foods to pureeing hot soups. Choose the model that suits your operation and its daily blending volume.
