Hello,
Thank you for getting in touch with Diageo regarding Guinness Draught.
Guinness Draught (canned, bottled and on tap) is now produced using a new filtration process that does not involve any animal-derived agents. The product is suitable for vegans. This change was made in late 2017 — prior to that date, isinglass (a fish-derived fining agent) was used during the clarification stage.
Please note that some Guinness variants brewed in other markets may still use traditional methods — we'd always advise checking the label for local production.
If you have any further questions about Diageo brands, please don't hesitate to get in touch.
Kind regards,
Niamh O'Brien
