Which kind of counter blender jar is better, glass or plastic? What are the differences between glass or polycarbonate blender jars, or does it really matter in the blending sphere?

The type of blender jar does not make any difference in (blender) performance or blending efficiency, with one exception. If a plastic jug interior has become etched (scratched) from use, contents might not blend (circulate in the jar) as thoroughly or smoothly.

It might also be more difficult to clean. This, of course, would be on the extreme scale and highly unusual.

Difference Between Glass and Plastic

There are, however, notable differences in durability, weight, clarity and features. Even then, the final buying decision often seems to come down to look and style, as well as user preference. For some, the blender jar style is not even a consideration.

Some consumers just love the glass jar because it looks nicer (retains its clarity), has a vintage appeal and feels better (heavier) than its poly counterpart. But one thing to keep in mind - it's a given that people who loathe drinking a beverage from plastic drinkware are more likely to prefer a glass (blender) jar.

Since blenders often come with practical accessories such as personal blending cups, it's not unusual to find a blending system that includes a large glass jug, as well as a smaller plastic , single serve blending jar, combining both of these styles.

Plastic personal blending cups are more practical for commuting. As for price, a glass jar blender used to cost more than poly models, but today, prices are fairly comparable and influenced more by the unit's power, speeds, preset settings, and accessories.

Glass has several benefits. It does not discolor or scratch, nor does it absorb food odors like a plastic jar might do.

When a blender is used for crushing ice, a plastic jar can become scratched over time, marring its clarity. Glass seems to retain it's good looks much longer.

Scratches or etching in the poly construction is also unavoidable when blending ice or hard food items such as shelled nuts. And pouring spouts are often more defined (efficient) and level markings are most often clearer in a poly jug.

A glass jar, however, is much heavier to handle and that may be a buying consideration for those with arthritic or problem hands, as well as for the elderly. These jars are not as durable (as plastic) as they are also more prone to breakage if dropped.

If glass is your preference, but handling is an issue, you might want to consider downsizing the blender to reduce the weight. Oftentimes, we buy a blender with a large capacity jar, when a smaller, high-powered model would better meet our blending needs.

There is a third type of blender jar that was more common with commercial blenders but has transitioned into the home counter blender industry - stainless steel.

These metal jugs are much more durable than plastic or glass, but can also influence the blender price. One drawback for this type is that you cannot monitor blended contents. Not a concern if you're careful to adhere to the manufacturer's recommended maximum blending level.
