I called them and they sent this email.
Dear Mr Singh,
Thank you for your enquiry regarding Barr/Rubicon products.
I would like to confirm that all our range is suitable for a vegetarian
diet except Sun Exotic Pineapple and Coconut juice and Sun Exotic
Tropical juice which is not suitable for Vegans.
I hope that this information is helpful.
Kind regards
