Non-pareil capers are the smallest and most expensive type of capers, measuring just ¼ inch (seven millimeters) in length. They are deep green, firm, and have delicate aromatic notes. They are typically packed in a sour salty brine preservative.
Surfines capers are slightly larger, measuring seven to 8 millimeters in diameter, and are either brined or packed in salt. They can be found in specialty food shops.
Cupacines capers are 8 to 9 millimeters in size, followed by capote capers at nine to 11 millimeters, and fines capers ranging from 11 to 13 millimeters. These larger sizes can be more difficult to find in grocery or specialty food stores.
Grusas capers are the largest variety, often exceeding 14 millimeters in diameter. They are also more acidic and rare, making them challenging to find in the United States.
To use capers, it is recommended to rinse off the salt or brine before adding them to dishes, blending them into tapenade, or garnishing cocktails. Once opened, capers should be refrigerated and can last up to six months for salt-packed capers or nine months for brined capers.
