Crisphead Lettuce

What to Look For

Lettuce leaves should be crisp and be a bright light green with a spherical shape. 

Ideal Storage

  • 0°C
  • 95-100% Relative Humidity

Under optimal conditions lettuce can keep for 21-28 days. At 5°C the shelf life is reduced to 14 days assuming there is no presence of ethylene. 

Keep lettuce away from drafts to prevent dehydration. 

Response to Ethylene

Crisphead lettuce is extremely sensitive to ethylene. Exposure will result in rusting and russet spotting (development of brown spots).
