The frappes are essentially smoothies and come in two flavours: Solera (passion fruit, mango and orange juice) and Berry Crush (raspberry, strawberry, grenadine and cranberry).
They join the Coffee Frappé and Caramel Coffee Frappé on TCG’s menu and will be available in around 30 of the company’s pubs and bars.
“Our coffee range, with its seasonal variants, has already helped our pubs and bars to compete with the many other coffee providers on the High Street,” said chief operating officer Nigel Wright.
“Customers now expect a very diverse range of drinks, and the addition of freshly made smoothies further broadens the choice we offer at our busy town centre sites, right throughout the day.”
TCG relaunched its entire coffee and hot drinks offer last summer, joining forces with Cafeology, an ethical coffee supplier.
It also rolled out a training programme at the same time, to equip staff with barista skills, in a bid to boost day time trade.
In December it launched a new cocktail menu featuring picklebacks (whiskey and a shot of pickling vinegar), claiming to be the first mainstream operator to do so.
