The sweetness of corn is a trait that has been refined over centuries through careful breeding and selection. From the succulent kernels of Silver Queen to the vibrant, multicolored harvests of Indian corn, the world of sweet corn is as diverse as it is delicious. But what makes some types of corn sweeter than others? And which variety holds the title for the sweetest of them all? In this article, we will delve into the world of sweet corn, exploring the science behind its sweetness, the different types of sweet corn, and ultimately, uncovering the sweetest corn available.
Understanding the Science of Sweet Corn
Sweet corn is a specific type of corn that is harvested when the kernels are immature and the sugar content is at its highest. Unlike field corn, which is allowed to mature fully and is used primarily for grain production, sweet corn is picked when the kernels are soft and the moisture content is high. This early harvest ensures that the natural sugars in the corn are preserved, giving sweet corn its characteristic sweetness.
The Role of Genetics in Sweet Corn Sweetness
The sweetness of corn is largely determined by genetics. Traditional sweet corn varieties contain a genetic trait known as the “sugary” gene, which slows down the conversion of sugars into starch during the maturation process. This results in a sweeter, tenderer kernel. However, modern breeding has introduced new genes that further enhance sweetness, such as the “shrunken” and “supersweet” genes. These genes not only increase the sugar content but also improve the texture and shelf life of the corn.
Supersweet Corn: The New Standard in Sweetness
Supersweet corn, developed in the 1950s, represented a significant breakthrough in sweet corn breeding. By incorporating the “shrunken-2” gene, supersweet corn varieties have a higher sugar content and a longer shelf life than traditional sweet corn. This is because the “shrunken-2” gene reduces the activity of an enzyme that breaks down sugars, resulting in a sweeter taste that lasts longer after harvest.
Exploring the Different Types of Sweet Corn
The world of sweet corn is incredibly diverse, with varieties ranging from the classic, white Silver Queen to the bi-colored and multicolored assortments found in many modern hybrids. Each type of sweet corn has its unique characteristics, advantages, and levels of sweetness.
Traditional Sweet Corn Varieties
Traditional sweet corn varieties, such as Stowell’s Evergreen and Golden Bantam, have been favorites among gardeners and consumers for centuries. These varieties are known for their rich, old-fashioned flavor and tender kernels. While they may not be as sweet as some of the newer hybrids, they offer a depth of flavor and a connection to the past that many find appealing.
Hybrid and Supersweet Varieties
Hybrid and supersweet varieties of corn, such as Silver Queen and Kandy Korn, have been bred for their exceptional sweetness and long shelf life. These varieties often contain the “sugary enhanced” or “shrunken-2” genes, which significantly increase their sugar content. They are popular among commercial farmers due to their high yield and resistance to disease, as well as among consumers for their unparalleled sweetness.

What are the main differences between sweet corn varieties?
The main differences between sweet corn varieties lie in their genetic makeup, which affects their sugar content, texture, and flavor. Some sweet corn varieties, such as Silver Queen and Golden Bantam, are known for their high sugar content and tender kernels, making them ideal for fresh eating and boiling. Other varieties, like Country Gentleman and Stowell’s Evergreen, have a harder outer layer and are better suited for canning and freezing. Understanding these differences is essential for growers and consumers alike, as it helps them choose the best variety for their specific needs.
In addition to their genetic differences, sweet corn varieties also vary in terms of their maturation days, plant height, and disease resistance. Some varieties, such as the popular hybrid variety, Miracle, mature in as little as 60 days, while others may take up to 90 days to reach full maturity. Plant height can also vary significantly, ranging from compact varieties like On Deck, which grow to around 4 feet tall, to taller varieties like Silver Queen, which can reach heights of over 6 feet. By considering these factors, growers can select the variety that best fits their climate, soil, and growing conditions, ensuring a successful and bountiful harvest.
How do I choose the sweetest sweet corn variety for my garden?
Choosing the sweetest sweet corn variety for your garden involves considering several factors, including your climate, soil type, and personal preferences. If you live in a cooler climate, you may want to opt for a variety that matures quickly, such as Early Sunglow or Quick Silver. If you prefer a sweeter corn, look for varieties that are high in sugar content, such as Silver Queen or Golden Bantam. You should also consider the amount of space you have available, as some varieties can grow quite tall and may require staking.
Before making a final decision, it’s a good idea to read reviews and talk to other gardeners who have experience growing sweet corn. They can provide valuable insights and recommendations based on their own experiences. You can also check with local nurseries or seed suppliers to see what varieties they recommend for your area. By doing your research and selecting a variety that is well-suited to your garden, you can enjoy a delicious and bountiful harvest of sweet corn. Additionally, be sure to follow proper growing and harvesting techniques to bring out the natural sweetness of your sweet corn.
What is the best way to grow sweet corn in a small garden?
Growing sweet corn in a small garden requires careful planning and attention to detail. To start, choose a variety that is compact or dwarf, such as On Deck or Honey and Cream, which are specifically bred for small gardens. These varieties are designed to grow in smaller spaces and produce smaller ears, making them ideal for containers or small plots. You should also make sure to provide your sweet corn with full sun and well-draining soil, as it requires a lot of sunlight and water to produce a healthy crop.
In addition to choosing the right variety, you should also consider using a technique called “block planting,” where you plant your sweet corn in a block rather than in long rows. This helps to improve pollination and reduce the amount of space required. You can also use companion planting to your advantage, by planting other vegetables like beans and squash around your sweet corn to help retain moisture and suppress weeds. By following these tips, you can successfully grow sweet corn in even the smallest of gardens and enjoy a delicious and rewarding harvest.
How do I know when my sweet corn is ready to harvest?
Knowing when your sweet corn is ready to harvest is crucial, as it can make a big difference in the flavor and texture of the corn. One way to check for readiness is to look for the silks, which are the long, thin strands that protrude from the top of the ear. When the silks are dry and brown, it’s usually a sign that the corn is ready to harvest. You can also check the kernels by pulling back the husk and squeezing one of the kernels. If the kernel is soft and milky, it’s not yet ready. If it’s firm and the liquid inside is clear, it’s ready to harvest.
Another way to check for readiness is to monitor the color of the ears. As the corn matures, the ears will begin to turn a lighter color and the husks will start to dry out. You can also check the consistency of the kernels by biting into one. If it’s sweet and tender, it’s ready to eat. It’s generally best to harvest sweet corn in the morning, after the dew has dried but before the heat of the day. This helps to preserve the natural sweetness of the corn and ensures that it stays fresh for a longer period.
Can I grow sweet corn in containers?
Yes, you can grow sweet corn in containers, but it requires careful planning and attention to detail. To start, choose a container that is at least 12 inches deep and has good drainage holes to prevent waterlogged soil. You should also choose a variety that is compact or dwarf, such as On Deck or Honey and Cream, which are specifically bred for container gardens. These varieties are designed to grow in smaller spaces and produce smaller ears, making them ideal for containers.
When growing sweet corn in containers, it’s essential to provide your plants with full sun and well-draining soil. You should also fertilize your plants regularly, using a balanced fertilizer that is high in phosphorus to promote healthy root growth. Additionally, you’ll need to water your plants frequently, as containers can dry out quickly. It’s also a good idea to use a trellis or other support system to help your plants grow upright and produce a healthy crop. By following these tips, you can successfully grow sweet corn in containers and enjoy a delicious and rewarding harvest.
How do I store sweet corn to preserve its freshness?
Storing sweet corn properly is essential to preserve its freshness and flavor. The best way to store sweet corn is to keep it cool and moist, as heat and dryness can cause the sugar in the corn to convert to starch, making it less sweet. You can store sweet corn in the refrigerator, where it will keep for up to a week. Simply place the ears in a plastic bag or wrap them in plastic wrap to keep them moist, and store them in the crisper drawer.
If you want to store sweet corn for longer periods, you can also consider freezing or canning it. To freeze sweet corn, simply blanch the ears in boiling water for 5-10 minutes, then chill them in an ice bath. Once chilled, you can remove the kernels from the cob and freeze them in airtight containers or freezer bags. To can sweet corn, you’ll need to use a pressure canner to ensure that the corn is properly sterilized and sealed. By following proper storage and preservation techniques, you can enjoy your sweet corn year-round and preserve its natural sweetness and flavor.
