Let’s dive in!

What Is a BlenderBottle?

A BlenderBottle is a brand of shaker bottle specially designed for mixing liquids and powders quickly and thoroughly. Its most notable feature is the Whisk Ball, a stainless steel spring-like wire that mimics the motion of a blender. When you shake the bottle, the Whisk Ball breaks up clumps and blends protein, smoothies, meal replacements, and more.

BlenderBottles are widely used in:

  • Fitness and athletic communities
  • Meal replacement users
  • Daily hydration routines
  • Smoothie lovers
  • Travellers and commuters

How many ounces: 32 fl oz

The 32 oz BlenderBottle is ideal for people who want extra volume — whether that’s a large shake, smoothie, or combined beverages (water + recovery drink).

  • Long workouts

  • Athletes
  • Long hiking or outdoor sessions
  • People who drink multiple supplements daily

Fluid Ounces vs. Dry Ounces — What’s the Difference?

One confusion people sometimes have with BlenderBottle sizes is the word “ounces.”

Here’s the difference:

  • Fluid ounces (fl oz): Measures liquid volume — what BlenderBottles list.
  • Dry ounces: Measures weight — used for solids like flour or protein powder.

So when we say a BlenderBottle holds 32 ounces, we mean 32 fl oz of liquid — not 32 ounces by weight.

A liquid ounce and a weight ounce are different:

  • 1 fl oz of water weighs about 1.04 ounces
  • But powders and solids weigh different amounts depending on density

For the purposes of a BlenderBottle, always think fluid ounces (volume).

How to Choose the Right BlenderBottle Size

Choosing the right size depends on your lifestyle and needs. Ask yourself:

1. How big are your drinks?

If you make la

  • Hydration drinks
  • Electrolyte mixes

That’s because the Whisk Ball mixes ingredients smoothly without a blender.

How Does the Whisk Ball Work?

The secret to a BlenderBottle’s effectiveness is the Whisk Ball, typically a stainless-steel spring. When you shake the bottle:

  1. Powder meets liquid

  2. The Whisk Ball breaks up clumps

  3. The result is smooth, well-mixed drinks

This makes them ideal when you’re:

  • In a hurry

  • At the gym

  • Packing lunch

  • Traveling
