Starbucks is to launch its Via Ready Brew in UK supermarkets. Starbucks’ Italian Roast and Columbia varieties will cost £1.39 for a three-pack and £2.99 for a sevenpack. The US giant launched its Stabucks Via Ready Brew in its 700 coffee houses a year ago. Now, it is to go on sale at Tesco with other supermarkets to follow later in the year.
