Canning Tomatoes

To embark on our journey of selecting the best tomatoes for canning, it’s essential to have a clear understanding of what canning tomatoes are and why they are distinct from other tomato varieties:

Defining Canning Tomatoes: Canning tomatoes, often referred to as processing tomatoes, are a category of tomato varieties specifically chosen for their suitability in canning and preserving. These tomatoes possess a set of characteristics that make them ideal for maintaining flavor, texture, and safety throughout the canning process.

Balanced Acidity: Canning tomatoes are known for their balanced acidity, with a pH level typically around 4.6 or lower. This balanced acidity is crucial for safe canning, as it helps inhibit the growth of harmful microorganisms that can spoil canned products.

Firm Texture: Unlike some tomato varieties that may be too soft or watery, canning tomatoes have firm, meaty flesh that holds its shape during processing. This characteristic ensures that the canned tomatoes or tomato products maintain their structural integrity.

Flavor Profile: Canning tomatoes are chosen for their flavor as well. While the specific taste may vary depending on the variety, these tomatoes generally offer a sweet and balanced flavor profile, making them a delightful addition to various recipes.

Qualities to Look for in Canning Tomatoes

When it comes to choosing the best tomatoes for canning, there are several key qualities to keep in mind. These qualities ensure that your canned tomato products are not only safe but also delicious and versatile:

Acidity: The acidity of tomatoes plays a crucial role in safe canning. Canning tomatoes should have a pH level of approximately 4.6 or lower. This level of acidity is important because it helps prevent the growth of harmful microorganisms like botulism during the canning process. Tomatoes with higher pH levels may not be suitable for canning without additional acidification.

Texture: Canning tomatoes should have firm, meaty flesh. Tomatoes with a good texture hold their shape well during processing, whether you’re canning whole tomatoes, tomato sauce, or diced tomatoes. This characteristic ensures that your canned products maintain their integrity and don’t turn mushy.

Flavor: While flavor can vary among tomato varieties, canning tomatoes are generally chosen for their pleasant and balanced flavor profile. Look for tomatoes that offer a combination of sweetness and acidity, as this results in a more delicious canned product. The goal is to preserve not only the texture but also the taste of the tomatoes.

Blemish-Free: When selecting tomatoes for canning, prioritize those that are free from significant blemishes, cracks, or signs of decay. While minor imperfections can be trimmed or removed during preparation, it’s best to start with tomatoes in good overall condition to ensure the highest quality canned products.

Understanding these essential qualities is the foundation for choosing the best tomatoes for your canning projects. However, the specific tomato varieties you select can also make a significant difference in the outcome of your canned goods.

Tips for Growing Canning Tomatoes

Growing your own canning tomatoes can be a rewarding experience that ensures you have a fresh and bountiful supply for preserving. Here are some tips to help you successfully cultivate canning tomatoes:

  1. Select the Right Varieties: Choose tomato varieties known for their suitability in canning, such as Roma, San Marzano, Amish Paste, or Celebrity tomatoes. These varieties have the desirable qualities of firm texture, balanced flavor, and ideal acidity.
  2. Proper Soil Preparation: Tomatoes thrive in well-drained soil rich in organic matter. Prepare your garden bed by incorporating compost or well-rotted manure to improve soil fertility and moisture retention.
  3. Adequate Spacing: Plant tomato seedlings with proper spacing to allow for good air circulation. This helps reduce the risk of fungal diseases that can affect your crop.
  4. Support and Pruning: Staking or caging tomato plants is essential to keep them off the ground and prevent fruit from touching the soil. Regularly prune tomato plants to remove lower leaves and encourage better air circulation, which can reduce the likelihood of diseases.
  5. Consistent Watering: Maintain consistent moisture levels in the soil. Tomatoes require even watering to prevent issues like cracking. Consider using drip irrigation to provide consistent moisture without wetting the foliage, which can lead to disease.
  6. Fertilize Appropriately: Tomatoes benefit from balanced fertilization. Apply a balanced fertilizer based on soil test results or follow general recommendations for tomato plants. Avoid excessive nitrogen, which can lead to excessive foliage growth at the expense of fruit production.
  7. Disease Management: Keep a watchful eye for common tomato diseases, such as early blight and late blight. Consider using disease-resistant tomato varieties and practicing crop rotation to minimize the risk.
  8. Prudent Pest Control: Protect your tomato plants from common pests like aphids, hornworms, and whiteflies. Employ natural predators or use organic pest control methods to avoid chemical residues on your tomatoes.

Harvesting and Preparing Canning Tomatoes

The process of growing canning tomatoes extends to harvesting and preparing them for canning:

  1. Timing: Harvest your tomatoes when they are fully ripe but not overripe. Look for vibrant colors and firmness as indicators of ripeness.
  2. Cleaning and Washing: Gently clean the harvested tomatoes to remove dirt and debris. Rinse them under cool, running water, and pat them dry with a clean towel.
  3. Peeling and Seeding: Depending on your canning recipe, you may need to peel and seed the tomatoes. To peel, blanch the tomatoes briefly in boiling water and then transfer them to an ice bath to make the skins easy to remove. To seed, simply cut the tomatoes in half horizontally and gently squeeze out the seeds.

Proper preparation of your canning tomatoes ensures that they are ready for the canning process, maintaining their quality and flavor in the final canned product.


Selecting, growing, harvesting, and preparing the best tomatoes for canning is a rewarding journey that results in delicious homemade canned products. The choices you make, from tomato varieties to cultivation practices, significantly impact the flavor and quality of your canned goods.
