Types of Sweet Corn

3 Types of Sweet Corn

There is no substitute for the flavor of sweet corn just picked from the farm. Flavor and adaptability to your farm’s climate are the major considerations when choosing a corn variety. There are three types of fresh-eating sweet corn grouped by flavor: standard corn, sugary enhanced corn, and super sweet corn (adaptability to your farm’s climate–the soil and air temperature–is actually linked to the flavor type). Here’s how these corn types differ:

  • Standard corn is the “old-fashioned” corn your grandfather grew; the corn with tasty corn flavor. These varieties–many are heirlooms and open-pollinated–have been around for years and years. Standard corn is plannable in cool soil, as cool as 55°F. This corn is best rushed to the kitchen and eaten within an hour of harvest.
  • Sugary enhanced corn is hybrid varieties that keep their sweet flavor up to 3 days after harvest. Sugary enhanced hybrids give growers a 3-day window for harvest. (Near harvest time it is important to monitor standard corn each day to make sure you pick at the peak of its sweet flavor.) Sugary enhanced cultivars don’t require daily monitoring; pick sugary enhanced corn anytime within the 3 day peak flavor period. This type of corn demands soil temperatures about 10° warmer than standard corn.

  • Super sweet corn is also hybrid varieties–the sweetest flavored of all corn. Super sweet corn varieties are sweeter than sugary enhanced varieties. Super sweets also have an enhanced harvest window of 3 to 5 days. One note, super sweet corn can be demanding: it requires soil no less than 65°F at planting time; it grows best when the soil is pre-warmed (cover beds with black plastic to warm the soil) and it is less vigorous than standard or sugary enhanced corn.
