Quart milk is typically sold as Fat Free (skim), 1% (low‑fat), and 2% (reduced‑fat).
Labels commonly show "Pasteurized" or "Ultra‑Pasteurized." Some products—particularly fat‑free or higher‑protein varieties—are labeled "ultra‑filtered."
Quart milk is commonly packaged in plastic bottles or paper/cardboard cartons, depending on the brand and product.
Labels frequently highlight vitamins A and D, calcium, and protein. Other commonly listed nutrients include niacin, riboflavin, potassium, and phosphorus.
Options include plain low‑fat or reduced‑fat milks, flavored varieties labeled with a flavor and "artificially flavored," and specialty formulations such as ultra‑filtered fat‑free milks that offer higher protein.
Some ultra‑filtered fat‑free quart milks are labeled lactose‑free and explicitly list higher protein (about 13 g per serving) compared with the typical 8 g found on many quarts.
