McDonald's is adding new breakfast sandwiches with 3 times as much meat to its menu. Here's how they actually taste.

First things first: The stacks are tall.

It's easy to feel like a cartoon character unhinging your jaw as you try and stuff the Biscuit Stack, the largest of the lot, into your mouth.

Despite the decadence, the flavor profile of all three sandwiches was generally embraced by taste testers.

The interplay of sausage and bacon — previously unheard of on a McDonald's breakfast sandwich — works disturbingly well, with the salty, savory flavors complementing each other nicely.

The second sausage, however, is a bit much. The syrupy McGriddle Stack, especially, packs in enough grease to immobilize the eater for the rest of the day.

Should you buy the Triple Breakfast Stacks? If you're a meat lover, this should be a no-brainer. These breakfast sandwiches push the limit on fast-food meat consumption to new heights.

McDonald's understands what makes a breakfast sandwich work. The Breakfast Triple Stacks are greasier than the average breakfast sandwich and won't replace the classics in our day-to-day diet. But, they're a disgustingly delectable addition.
