The question of whether tomatoes should be stored stem up or stem down has sparked a lively debate among food enthusiasts, chefs, and home cooks. While it may seem like a trivial matter, the way you store your tomatoes can significantly impact their freshness, flavor, and overall quality. In this article, we will delve into the world of tomato storage, exploring the pros and cons of each method, and providing you with the knowledge to make an informed decision.
Understanding Tomato Anatomy
Before we dive into the storage debate, it’s essential to understand the anatomy of a tomato. Tomatoes are a type of fruit that belongs to the nightshade family. They have a soft, juicy flesh and a tough, outer skin that protects them from damage. The stem, also known as the calyx, is the part of the tomato that attaches it to the plant. It’s usually removed before consumption, but it plays a crucial role in the storage process.
The Role of the Stem in Tomato Storage
The stem is the weakest point of the tomato, making it susceptible to moisture and bacterial infiltration. When the stem is exposed to air, it can dry out, reducing the risk of mold and decay. However, if the stem is in contact with a surface, it can create a conduit for moisture and bacteria to enter the tomato, leading to spoilage. This is where the debate between storing tomatoes stem up or stem down comes into play.
Stem Up Storage: The Traditional Method
Storing tomatoes stem up is the traditional method that has been used for centuries. This approach involves placing the tomatoes on a surface, stem side up, to prevent moisture from accumulating on the stem. Proponents of this method argue that it reduces the risk of mold and decay, as the stem is exposed to air, allowing it to dry out. Additionally, storing tomatoes stem up can help to prevent the transfer of bacteria and other microorganisms from the surface to the tomato.
Stem Down Storage: The Modern Approach
In recent years, a new approach to tomato storage has gained popularity: storing them stem down. This method involves placing the tomatoes on a surface, stem side down, to prevent moisture from entering the fruit through the stem. Advocates of this method claim that it reduces the risk of moisture accumulation and prevents bacteria from entering the tomato through the stem. Furthermore, storing tomatoes stem down can help to maintain their natural moisture barrier, keeping them fresher for longer.
The Science Behind Tomato Storage
To better understand the effects of storage on tomatoes, let’s examine the science behind it. Tomatoes, like all fruits, undergo a process called respiration, where they release carbon dioxide and absorb oxygen. This process can lead to a loss of moisture, flavor, and texture. Temperature, humidity, and ethylene production are the key factors that influence the storage life of tomatoes.
Temperature and Humidity
Temperature and humidity play a crucial role in tomato storage. Tomatoes should be stored at a consistent temperature between 50°F and 60°F, as higher temperatures can accelerate ripening and spoilage. Humidity is also essential, as high humidity can lead to moisture accumulation and mold growth. A relative humidity of 80-90% is ideal for storing tomatoes, as it maintains the natural moisture barrier of the fruit.
Ethylene Production
Ethylene is a natural gas produced by fruits, including tomatoes, as they ripen. High ethylene levels can accelerate ripening and spoilage, so it’s essential to store tomatoes in a way that minimizes ethylene production. Storing tomatoes in a cool, dry place, away from direct sunlight and heat sources, can help to reduce ethylene production and maintain their freshness.
Practical Tips for Storing Tomatoes
Whether you choose to store your tomatoes stem up or stem down, there are some practical tips to keep in mind:
- Store tomatoes at room temperature, away from direct sunlight and heat sources.

Refrigeration can cause tomatoes to lose their flavor and texture, while high temperatures can lead to spoilage. The ideal storage temperature for tomatoes is between 55°F and 65°F (13°C and 18°C), which slows down the ripening process without causing damage to the fruit. By maintaining a consistent temperature, you can help extend the shelf life of your tomatoes.
In addition to maintaining a suitable temperature, it is also important to monitor the tomatoes’ condition regularly. Check for signs of spoilage, such as mold, soft spots, or an off smell, and remove any affected tomatoes to prevent the spoilage from spreading. By combining proper temperature control with careful handling and monitoring, you can enjoy fresh, flavorful tomatoes for a longer period, regardless of whether you store them with the stem up or down. This attention to detail will help you get the most out of your tomatoes and make the most of your storage efforts.
Can storing tomatoes with the stem down lead to increased moisture accumulation?
One of the primary concerns with storing tomatoes with the stem down is that it may lead to increased moisture accumulation. The stem scar, where the tomato was attached to the plant, can be a vulnerable point for moisture entry. When the tomato is stored with the stem down, there is a risk that moisture may collect in the concave area around the stem scar, potentially leading to mold and spoilage. However, this risk can be mitigated by ensuring the tomatoes are dry and free of excess moisture before storage. By gently wiping the tomatoes with a clean cloth or paper towel, you can reduce the likelihood of moisture accumulation.
It is also worth noting that the type of tomato can influence its susceptibility to moisture accumulation. Some tomato varieties, such as cherry or grape tomatoes, may be more prone to moisture-related issues due to their smaller size and higher surface-area-to-volume ratio. In contrast, larger tomato varieties may be less susceptible to moisture accumulation. By considering the specific characteristics of your tomatoes and taking steps to minimize moisture, you can reduce the risks associated with storing them with the stem down. With proper care and attention, you can enjoy fresh, healthy tomatoes, regardless of their storage position.
