How Long does a Whole Jamón last?
A whole Jamon leg can last up to 9 months unopened and around 6-8 weeks once opened from its airtight seal. You can store it on the ham holder provided by Ibérico Club, over the kitchen countertop away from any direct heat source. Once you start slicing your jamón, make sure to cover the exposed meat surface with slices of its own fat and cover the ham with a regular kitchen cloth.
