I recently came across Slate protein shakes at Kroger, a brand I hadn’t heard of before. Apparently, they’re the official partner of the UFC, so MMA fans ar likely to be familiar with them.

What caught my attention was the “ultra-filtered milk” on the label – the same ingredient that makes Fairlife shakes stand out in the protein shake market.

For those unfamiliar, Fairlife shakes taste like milkshakes rather than protein shakes because they use ultra-filtered milk instead of adding protein supplements. In other words, they are simply adding back extra protein from the milk itself rather than adding a protein powder to the shakes.

Seeing Slate use the same approach, I was excited to give them a try. Slate offers both protein shakes and coffee options, but I focused on their two chocolate flavors for this review.

Nutritionally, these shakes are impressive:

Slate protein shake macros
  • 100 Calories
  • No added sugar
  • 20 grams of protein
  • Lactose-free

These stats are solid, especially considering the low calorie count. If the taste matches up to Fairlife, Slate could be a strong contender in the protein shake market.

Flavor Review: Classic Chocolate

The Classic Chocolate was quite dark and bitter, which wasn’t what I expected. I was hoping for a smooth chocolate milk flavor similar to Fairlife, but that’s not what I got here.

It doesn’t necessarily taste like a typical protein shake, but you wouldn’t mistake it for chocolate milk either.

There’s a noticeable lack of sweetness, and I detected a hint of stevia aftertaste. While not bad, it doesn’t have the smooth flavor profile of Fairlife, which is what I hoped for from an “ultra-filtered milk” product.

The taste reminds me more of hot chocolate mix mixed with water than creamy chocolate milk, so set your expectations accordingly.

Flavor Review: Dark Chocolate

The Dark Chocolate flavor is very similar to the Classic Chocolate, but with a more pronounced aftertaste. Surprisingly, it tastes almost like a watered-down version of the Classic Chocolate. This was disappointing, as you’d expect dark chocolate to have a stronger cocoa flavor.

If I were choosing between the two, I would take classic chocolate 10 times out of 10 over dark chocolate. If you’re expecting a rich dark chocolate flavor, you’re going to be sorely disappointed.

Slate Protein Shakes: Final Thoughts

Overall, I find the Classic Chocolate flavor to be decent, though not anywhere close to Fairlife. It’s enjoyable enough if you can find it on sale, but I wouldn’t be racing out to stock up.

Unlike Fairlife, which can easily be mistaken for regular chocolate milk in a blind taste test, Slate definitely stands apart from typical chocolate milk.

Considering each shake contains 100 calories and 20 grams of protein, it’s not a bad option. The flavor won’t blow you away, but it’s serviceable for a quick protein boost without excessive calories.

Slate does offer other flavors, like french vanilla, so maybe you’ll find better luck with different flavor options. As it currently stands, I could see a place for the classic chocolate shake, but don’t expect Fairlife-level deliciousness.

Summary
Slate Protein Shakes offer impressive macros, but fall short in the flavor department compared to top competitors like Fairlife. They're worth trying if you find them on sale and are looking for a low-calorie, high-protein option. Even though they are made with "ultra-filtered milk" like Fairlife, don't expect these to taste anywhere close.
