Does 100% grass fed mean grass finished too?

No, "100% grass-fed" does not necessarily mean that the animal is also grass-finished. Grass-fed indicates that the animal was fed grass or forage for its entire life, but it does not specify how the animal was finished before slaughter.

"Grass-finished" means that the animal was not only grass-fed throughout its life but also continued to eat grass or forage up until the point of processing. Some animals may be grain-finished or fed other feedstuffs during the final stages to achieve certain weight or quality standards. Therefore, if you're looking for both grass-fed and grass-finished products, it’s important to verify that claim specifically on the packaging or through the supplier.
