The pungent or strong-flavored varieties and the milder ones. Milder varieties include Slicing varieties that we use for onion rings and sandwiches, like 'Sweet Spanish', and big red onions.

Grouping onions by Storage qualities is another method. . The most popular storage onions are pungent strong flavored yellow ones . Commercial growers like these onions because they store them for long periods of time and can be shipped greater distances. The milder Bermuda and Spanish onions can't be stored for very long.

For Marketing & Culinary purposes Onions are generally categorized into the following

WHITE ONIONS: Glossy white appearance. One of the more pungent onions. Use raw on burgers, sandwiches, salsa and similar dishes if you like warm, but real tasty onions. Otherwise, they can be used in any recipe that calls for cooked onions.

YELLOW ONIONS: Golden color with relatively strong flavor. May be used cooked or raw, depending on your taste for a somewhat pungent onion. Long, slow sautéing at very low heat brings out sweet, mellow flavors.

RED ONIONS: Purplish rather than red, they are relatively mild. Appealing in salads or sautéed in stir fries. Also good for many other recipes. Adding a bit of vinegar, wine or lemon juice helps keep color from fading or turning purplish-blue. You'll often find red onions in salads at restaurants.

SHALLOT: This is not a true onion, it is a small relative of the onion with dry, coppery skin. The flavor combines onions and garlic. Hot when raw, but cooks to a delicate flavor.

SCALLIONS: This is a variety of onions that is harvested before the bulb has formed. Mild flavor. Green onions have tiny white bulbs at the bottom while scallions are younger and have straight white sides at the root end.

LEEKS: In the scallion family. It looks like a large, fat scallion with a white root and dark green, overlapping leaves. Only the root is used. Careful trimming and cleaning are necessary because dirt can accumulate in leaves. Leeks are not true Onions as per many "experts', but in my book if it looks like a duck, quacks like a duck and tastes like a duck - it's a Duck. Or an Onion as the case may be.
