Grass-fed vs. grass-finished beef
A lifetime grass-fed claim includes the finishing period. Grass-finished refers to the diet before slaughter. For a specific beef product, check the complete feeding claim rather than assuming that grazing means an all-grass diet.

USDA’s grass-fed definition describes a grass-and-forage diet throughout the animal’s life, except for milk before weaning. It excludes grain and grain byproducts. That lifetime definition includes finishing; a producer’s general description of pasture grazing is less specific. USDA explanation of grass-fed meat
Pasture is a separate question
Where an animal lives and what it eats are related, but different. A pasture-raised claim does not, by itself, tell you whether grain was part of its diet. Compare feeding and outdoor-access details separately.
