From fragrant magnolia blossom to roses in the king’s courtyard, the gardens at Highgrove have inspired a new collection of bottlegreen cordials, this October 2026 – bringing together two celebrated Gloucestershire names in a new product line.
Cotswolds drinks producer bottlegreen has partnered with Highgrove to launch three flavours, each presented in beautifully illustrated bottles – with 25p from every bottle sold supporting The King's Foundation's charitable work.
The collaboration has particularly close Gloucestershire roots, with the 15-acre organic gardens surrounding King Charles III and Queen Camilla’s private residence in Tetbury just a few miles from bottlegreen’s longstanding factory in Frogmarsh Mill in South Woodchester, near Stroud.
Crafted in small batches using spring water from bottlegreen’s original mill and traditional winemaking methods, the collection includes Magnolia and Elderflower, English Rose and Raspberry, and Rhubarb and Ginger.
British raspberry juice and fragrant English rose extract give the rose cordial its fruit-and-flower pairing, while pressed British rhubarb juice meets warming ginger in a flavour combination well suited to autumn entertaining.
The inspiration came during a walking tour of Highgrove Gardens by bottlegreen flavour expert Lynne McAlpine: stunning magnolia in blossom, an impressive kitchen garden rhubarb patch and elderflower bushes surrounding the gardens all helped shape the collection, with the famous king's courtyard roses given a special place in the range, too.
Designed to be enjoyed with still or sparkling water, the bottlegreen say the cordials can also add a 'botanical flourish' to spritzes, cocktails and alcohol-free drinks – served simply over ice or dressed with fruit for a more elaborate occasion.
Alongside its role as custodian of Highgrove Gardens, The King’s Foundation supports sustainable communities through practical education, traditional skills training and regeneration projects, with heritage and craft courses taking place at Highgrove itself.
The bottlegreen x Highgrove collection is available now from Waitrose, priced at £4.99 per bottle.
