Plenish is a UK plant-based drinks company founded in 2012 by Kara Rosen. Rosen started the business in her kitchen after moving from New York to the UK and struggling to find healthy, sugar-free cold-pressed juices. She began making her own juices and nut milks using organic vegetables and natural ingredients. What started as a small kitchen project quickly grew into one of the UK’s first cold-pressed juice brands, later expanding into plant-based milks, juice shots, and other health-focused drinks. In 2021, the company was acquired by Britvic, helping the brand expand further within the fast-growing plant-based drinks market.
