Grey Poupon bottles typically do not feature a resealable cap in the traditional sense. The classic design includes a twist-off cap that must be removed entirely to access the mustard, which is common for many gourmet condiment brands. While this twist-off cap allows for easy dispensing, it does not provide a resealable option that would allow the cap to be easily put back on after each use in a way that creates an airtight seal. However, consumers often find that the bottle is easy to store in the refrigerator after use, where it can maintain freshness for a reasonable period.
