Lettuce is native to Asia. The first written references to lettuce date back to ancient Egypt, where it was cultivated as early as 2000 BC. The ancient Egyptians used lettuce in their religious rituals and also as food.

Lettuce spread to Greece and Rome in antiquity. The Romans valued it for its flavor and medicinal properties. The Romans were the ones who introduced lettuce to Europe, where it has been cultivated ever since.



There are numerous varieties of lettuce, each with unique characteristics and flavors, as well as different preservation requirements. Lettuce varieties are classified based on their shape, color, and taste.

  • Based on shape, lettuces are classified into:
    • Leaf lettuces: have flat leaves and do not form heads.
    • Head lettuces: have leaves that roll up to form a head.

    Based on color, lettuces are classified into:

    • Green leaf lettuces: are the most common. They have light green or dark green leaves.
    • Red leaf lettuces: have red or purple leaves.
    • Yellow leaf lettuces: have yellow leaves.

    Based on taste, lettuces are classified into:

    • Bitter tasting lettuces: are the most traditional. They have a bitter taste that can be pleasant or unpleasant.
    • Mild tasting lettuces: have a mild and delicate flavor.

    Some of the most common lettuce varieties are:

    • Romaine lettuce: has long, narrow, dark green leaves. It has a bitter taste.
    • Iceberg lettuce: has crispy, light green leaves. It has a mild taste.
    • Green leaf lettuce: has flat, light green leaves. It has a mild taste.
    • Red leaf lettuce: has red or purple leaves. It has a mild taste.


Lettuce can be grown in almost any climate, but the best conditions are in temperate climates. Lettuce can be planted in spring, summer, or fall, but the best harvests are obtained in spring and fall.
In Spain, lettuce can be obtained year-round, although the season varies depending on the area. Our season in the east extends from October to March. During these months, lettuce is at its best, with optimal flavor and texture.

The leaf lettuce varieties, such as romaine, green leaf, and red leaf lettuce, have a shorter growing cycle than head varieties, like iceberg lettuce. Therefore, these leaf varieties are usually available throughout the season. Head varieties, on the other hand, have a longer growing cycle and are typically harvested in spring and fall.

Proper Storage of Lettuce for Distribution

Proper storage of lettuce is crucial to maintaining its freshness and quality throughout the distribution process. Below are some tips to ensure proper storage:

  1. Temperature: Lettuce should be stored at a temperature between 1-2°C to slow down its deterioration process. It’s important to avoid freezing, as this can affect the texture and quality of the lettuce.
  2. Humidity: Lettuce is a vegetable with a high water content, so it is essential to keep it in a humid environment to prevent wilting. A humidity level of 90-95% is recommended, usually maintained by periodic water sprays.
  3. Ventilation: It’s essential to ensure good air circulation around the lettuce to prevent moisture buildup and bacterial proliferation. It’s recommended to use perforated containers or plastic bags with small holes to allow ventilation.
  4. Light: Lettuce should be stored in a dark place to protect it from direct light exposure, as this can accelerate deterioration and cause changes in color and flavor.
