The warehouse buildings on Terminal Street in Charlestown are nondescript, but one is headquarters to a gastronomic jewel. Down a long corridor, double doors open to a suite of unadorned rooms and a treasure trove of exotic and premium quality food products. This is the home of OliveNation, an online business that sells over 500 items sourced from across the globe.

Racks bulge with selections of unusual ingredients not readily available at supermarkets. There are containers of grains of paradise, a pungent West African spice; South Asian black beluga lentils; black truffle tapenade from Italy; Moroccan organic argan oil; unfiltered bittersweet chardonnay vinegar from Spain. Employees are hustling to box up orders as quickly as they come in.
