Essential Spice Green Peppercorns are sourced from India. Green Peppercorns are very similar to black peppercorns. They are both the unripe fruit of the same vine and can be picked at the same time. Unlike the heat drying process used to produce black peppercorns, green peppercorns are plucked from the peppercorn vine and then boiled, washed with potassium sulphite to halt the oxidization process (that would cause the green peppercorn to turn black), and then freeze dried or dehydrated. Green Peppercorns have a lightly floral flavor and aroma, with brisk pepper-pine notes and an unobtrusive heat that quickly fades. These have less of a sharp than black or white peppercorns.
