5J ham is made of black pig and pork raised in the forest pasture of Iberia, in the middle and west of Spain. The first ham was made in a slaughterhouse in Iberia in 1879. At first, 5J ham was mainly used by nobles, and then it was mainly supplied to some five-star hotels in Spain. With the great integration of global trade, it was supplied to people in countries in need all over the world.
6J ham is relatively cheaper.
