Seattle-based coffee giant Starbucks has partnered with micro blogging site Twitter to launch a new service, called Tweet-a-coffee, to gift its beverages.

Designed to promote gifting on Twitter, the newly launched service is still in beta testing and is being introduced around the 2013 holiday season.

Using the service, anyone can send $5 Starbucks eGift card through a tweet.

The first 100,000 customers who tweet gift cards up to 6 November using their Visa card will get a $5 Starbucks e-card in return. The users can redeem the eGift card either by printing it out or by loading it onto a Starbucks digital card.

Starbucks chief digital officer Adam Brotman said: "What’s so exciting about extending our eGifitng platform to twitter is the open and real time nature of the platform.

"Tweet-a-coffee allows us to do something quite different in eGifting in that people can now give the gift of Starbucks to anyone on Twitter in the moment."

Starbucks’ eGifting platform was originally launched in 2011 on, which was later extended to Facebook, and its iPhone mobile app.
