The world of tomatoes is vast and varied, a vibrant landscape filled with juicy globes of red, yellow, and even purple hues. Amidst this colorful array, two tomato varieties often find themselves in the spotlight: plum tomatoes and San Marzano tomatoes. While both are celebrated for their elongated shape and meaty texture, confusion often arises about whether they are, in fact, the same. This article delves deep into the characteristics of each, exploring their differences and similarities to finally answer the question: Are plum tomatoes the same as San Marzano?
Unveiling the Plum Tomato: A Versatile Culinary Staple
Plum tomatoes, as the name suggests, are characterized by their oval or oblong shape, resembling a plum. They are a popular choice in kitchens worldwide, favored for their versatility and suitability for a wide range of culinary applications.
Defining Characteristics of Plum Tomatoes
Plum tomatoes are generally medium-sized, with a firm, meaty flesh and relatively few seeds compared to round tomatoes. They have a lower water content, making them ideal for sauces and pastes, as they cook down quickly and thicken easily. Their flavor is typically described as sweet and slightly acidic, providing a well-balanced taste profile.
Culinary Applications of Plum Tomatoes
The versatility of plum tomatoes is a key factor in their widespread popularity. They are a workhorse in the kitchen, lending themselves well to a multitude of dishes.
Plum tomatoes are a quintessential ingredient in Italian cuisine, where they are used to create rich and flavorful sauces for pasta, pizza, and other dishes. Their low water content and meaty texture make them perfect for achieving a thick and concentrated sauce. They are also commonly used in canning, preserving, and sun-drying. Their firm flesh holds up well during processing, ensuring a high-quality end product.
Beyond Italian fare, plum tomatoes find their way into stews, soups, and chili. They add body and depth of flavor to these dishes, providing a satisfying texture and taste. Roasting plum tomatoes brings out their sweetness and intensifies their flavor, making them a delicious addition to salads, appetizers, and side dishes.
Popular Varieties of Plum Tomatoes
Several varieties of plum tomatoes are widely available, each with its unique characteristics. Roma tomatoes are perhaps the most common type of plum tomato, known for their reliable flavor and availability. Amish Paste tomatoes are an heirloom variety prized for their rich, sweet taste and dense flesh. Other notable varieties include Big Mama, Martino’s Roma, and Heidi.
Decoding the San Marzano: The King of Italian Tomatoes
San Marzano tomatoes are widely regarded as the gold standard of plum tomatoes, particularly in Italian cuisine. They are revered for their exceptional flavor, texture, and suitability for making authentic Neapolitan pizza sauce.
Defining Characteristics of San Marzano Tomatoes
San Marzano tomatoes are a specific type of plum tomato that originates from the volcanic plains south of Mount Vesuvius in Italy. They are typically longer and thinner than other plum tomato varieties, with a pointed end. They boast a vibrant red color, a firm flesh, and very few seeds.
The flavor of San Marzano tomatoes is what truly sets them apart. They are known for their intense sweetness, balanced acidity, and rich, complex flavor profile. Many describe the taste as slightly sweet, with a subtle hint of bitterness and a distinct umami character.
The Significance of “Pomodoro San Marzano dell’Agro Sarnese-Nocerino D.O.P.”
Genuine San Marzano tomatoes bear the “Pomodoro San Marzano dell’Agro Sarnese-Nocerino D.O.P.” certification. This certification guarantees that the tomatoes were grown in the designated region of Italy, using specific cultivation methods, and meet strict quality standards. The D.O.P. (Denominazione di Origine Protetta) designation protects the authenticity and integrity of San Marzano tomatoes.
Culinary Applications of San Marzano Tomatoes
San Marzano tomatoes are highly prized for making authentic Italian tomato sauce, especially for Neapolitan pizza. Their exceptional flavor, low acidity, and minimal seed content result in a sauce that is both sweet and tangy, with a smooth and velvety texture. They are also excellent for canning and preserving, as their firm flesh and intense flavor hold up well during processing.
While San Marzano tomatoes can be used in a variety of dishes, their superior flavor is best appreciated in simple preparations that allow their natural sweetness and complexity to shine through.
Why are San Marzano Tomatoes so Special?
Several factors contribute to the unique qualities of San Marzano tomatoes. The volcanic soil in which they are grown is rich in minerals, which contribute to their intense flavor. The Mediterranean climate, with its warm sunny days and cool nights, provides ideal growing conditions. Traditional cultivation methods, passed down through generations of farmers, also play a role in preserving the quality and authenticity of San Marzano tomatoes.

Are Plum Tomatoes Always San Marzano Tomatoes?
No, plum tomatoes and San Marzano tomatoes are not the same. Plum tomatoes are a general category of tomatoes characterized by their elongated, oval shape, meaty texture, and relatively few seeds. They are frequently used in sauces and canning due to their low water content and robust flavor, making them ideal for cooking down into concentrated pastes and sauces.
San Marzano tomatoes, on the other hand, are a specific variety of plum tomato originating from the San Marzano region of Italy. They are prized for their sweet, less acidic flavor, firm flesh, and thin skin. Authentic San Marzano tomatoes, grown in the designated region and adhering to specific cultivation standards, carry a DOP (Denominazione di Origine Protetta) certification, ensuring their quality and authenticity.
What Makes San Marzano Tomatoes So Special?
The exceptional quality of San Marzano tomatoes stems from a combination of factors. The volcanic soil in the Agro Sarnese-Nocerino region near Mount Vesuvius, where they are traditionally grown, is rich in minerals that contribute to their unique flavor profile. The specific climate and growing conditions also play a crucial role in developing their sweetness and low acidity.
Furthermore, authentic San Marzano tomatoes are cultivated according to strict guidelines to maintain their quality. These include specific irrigation techniques, harvesting methods, and processing standards. These factors, coupled with their naturally sweet and slightly tangy taste, make them highly sought after by chefs and home cooks alike.
How Can I Identify Authentic San Marzano Tomatoes?
To identify authentic San Marzano tomatoes, look for the DOP (Denominazione di Origine Protetta) seal on the can. This certification guarantees that the tomatoes were grown in the designated San Marzano region of Italy and meet specific quality standards. The can should also state “Pomodoro San Marzano dell’Agro Sarnese-Nocerino DOP.”
Be wary of imitations. Some companies may label their tomatoes as “San Marzano style” or “San Marzano type,” which indicates that they are not genuine San Marzano tomatoes grown in the protected region. Reading the label carefully and looking for the DOP seal is the most reliable way to ensure you are purchasing authentic San Marzano tomatoes.
Are San Marzano Tomatoes Worth the Extra Cost?
Whether San Marzano tomatoes are worth the extra cost depends on your personal preferences and the intended use. Their superior flavor, sweetness, and low acidity often translate into a richer and more complex sauce compared to sauces made with other plum tomatoes. If you are making a special dish where the tomato flavor is central, the investment may be worthwhile.
However, for everyday cooking or recipes where the tomato flavor is less prominent, using other high-quality plum tomatoes may suffice. The price difference can be significant, and for certain dishes, the subtle nuances of San Marzano tomatoes might not be readily apparent. Ultimately, the decision depends on your budget and your desired level of flavor sophistication.
Can I Grow My Own San Marzano Tomatoes?
Yes, you can grow your own San Marzano tomatoes, but keep in mind that the flavor might not be exactly the same as those grown in Italy’s San Marzano region due to differences in soil, climate, and growing conditions. You can purchase San Marzano tomato seeds or seedlings from many nurseries and online retailers.
To maximize your chances of success, provide your plants with plenty of sunlight, well-drained soil, and regular watering. Consider amending your soil with compost or other organic matter to improve its fertility. While you may not be able to replicate the exact conditions of the Agro Sarnese-Nocerino region, you can still enjoy the delicious flavor of homegrown San Marzano tomatoes.
What Are Some Good Substitutes for San Marzano Tomatoes?
If you cannot find or afford San Marzano tomatoes, there are several good substitutes. Other varieties of plum tomatoes, such as Roma tomatoes or Amish Paste tomatoes, can be used in their place. These varieties offer a similar meaty texture and low water content, making them suitable for sauces and canning.
You can also enhance the flavor of these substitutes by adding a pinch of sugar to reduce acidity or by using a high-quality tomato paste to deepen the tomato flavor. Experiment with different varieties and techniques to find the best substitute that suits your taste and budget. Ultimately, the best substitute will depend on your preferences and the specific requirements of your recipe.
How Should I Store San Marzano Tomatoes?
Unopened cans of San Marzano tomatoes should be stored in a cool, dry place away from direct sunlight. Once opened, transfer any unused tomatoes to an airtight container and refrigerate. They should be used within a few days to maintain their quality and prevent spoilage.
If you are using fresh San Marzano tomatoes, store them at room temperature until they are ripe. Once ripe, they can be stored in the refrigerator to prolong their shelf life. Avoid storing tomatoes in the refrigerator before they are ripe, as this can negatively affect their flavor and texture. Properly stored San Marzano tomatoes will retain their flavor and quality for a longer period.
