From the roaster

Mainstay is a blend of Latin American and East African coffees. Each bag includes six packets containing five grams of instant coffee. Simply add eight to ten ounces of filtered water (hot or cold) to a packet, stir and enjoy!

This instant coffee was produced by our friends, and Passenger alumni, Swift Coffee. Swift extracts the soluble material from coffee roasted by Passenger and then freeze-dries it, removing the water and leaving what can be rehydrated and enjoyed instantly. Stored away from moisture and light, this instant coffee will stay good indefinitely and is perfect for camping, road trips, flying on a plane, or lazy weekend mornings.
