Starbucks will expand its Reserve coffee line to 1,500 locations worldwide, and open at least 100 stores for the brand in the next five years.

The company is launching an interactive Reserve Roastery and Tasting Room for roasting, coffee education and increased availability of the Reserve coffees. It will also test small-footprint, express stores in 2015.

Starbucks chairman, president and CEO Howard Schultz said: "The Starbucks Reserve Roastery and Tasting room is a multi-sensory experience that will transform the future of specialty coffee.

"We plan to take this super premium experience to cities around the world, elevating the Starbucks experience not only through these stores but across our entire business."

The first Starbucks Reserve Roastery and Tasting Room will be opened in December this year.

Starbucks will invest in smaller, alternative store footprints that address the increase in urbanization and decentralization of retail.

Starbucks Americas and Teavana president Cliff Burrows said: "The evolution of our store experience is a direct reflection of how our customers are interested in both accessibility to the brand as well as speed and convenience.

"Our scale affords us the unique opportunity to bring a flexible portfolio of options rooted in our core commitment to coffee quality."
