Croxsons and Encirc have begun production of Sovereign, the UK’s first British-made sparkling wine bottle, created for English and Welsh producers as the sector expands and seeks a domestic alternative to imported glass. Made in Cheshire with 49% post-consumer recycled glass, the amber bottle offers up to 99% UV protection, supports a more localised and resilient supply chain, and is already being adopted by producers including Three Choirs and Ridgeview.
