Coffee chain Starbucks is refreshing its corporate logo as it celebrates its 40th anniversary. From 8 March, the evolved logo will appear on cups, menu boards and napkins, initially at 80 UK outlets. The revisions will see the Starbuck’s siren given increased prominence with a “cleaner, more contemporary” design. It also removes the Starbucks name from the logo for the first time. The new look can be viewed ahead of launch at Starbucks believes the refresh will allow it to explore new opportunities as it looks to diversify into new markets and areas such as retail. As part of the refresh, UK stores will also be replacing their stock of ceramic mugs this year in favour of something slimmer and lighter. The company, which opened its first store in Seattle’s Pike Place Market, is currently locked in a legal tussle in the US with Kraft Foods relating to the termination of a supermarket supply deal.
