Siren Craft Brew has some vegan options

Company email (October 2024) "I've just heard back from our brewery team - Lumina Session IPA and Mesmerist Pale Ale are both vegan in cask. Soundwave and Yu Lu sometimes get isinglass finings and sometimes don't (hopefully a sign that they can be produced as vegan going forward). I believe we often tell the sites purchasing the beers if they are vegan or not, so if you were to visit a site that has Soundwave or Yu Lu on cask, they may be able to inform you further. But Lumina and Mesmerist are definitely Vegan on cask at all times!" Company email (October 2022) "Thanks for getting in touch. We do have a wide selection of vegan beers in can and keg. As a general rule, if the beer is vegan in can form, it will be the same in Keg. Cask is slightly different due to filtration, but vegan beers that can be found in Cask are 'Lumina' and 'Suspended In'. Unfortunately, Broken Dream is not a vegan beer in any form (due to lactose). "If you haven't seen it already, here's a list of our currently available vegan beers in can form: https://www.sirencraftbrew.com/browse/beers/vegan" Company email (July 2019) "We don’t have a definitive list, no. However I can tell you: Broken Dream - Not vegan (contains lactose) Soundwave - Vegan friendly Calypso - Vegan friendly Yu Lu Vegan friendly in cans / keg but not cask. Suspended in… series - Vegan friendly in both keg and cask. Undercurrent - vegan friendly in bottles and keg, not on cask. "Special beers will have ingredients listed, but you’re only really looking out for honey or lactose. "New cans are all listed as Vegetarian or vegan friendly." Company email (December 2017) re Metafiction "Yep [Metafiction] certainly is [vegan]. The majority of our keg/bottle beers are vegan, it’s pretty much just those with additions like lactose that won’t be." Company email (July 2017) "Cask tends to use isinglass and some beers use lactose, really depends on the beer." Note from Andy (February 2015): "I’m writing to inform you about Siren Craft Brewery’s Broken Dream. You have it listed as vegan in keg and bottle, but unfortunately after visiting the brewery website and seeing them talk about “milk” in this beer I checked the ingredients on the bottle and it definitely lists “lactose”." Company email (February 2014): "Unfortunately all our cask beers do contain isinglass (British public and there concern for Cristal clear beer!!) However, you are completely safe with both our keg and bottles across the board." Company email (October 2013): "All our cask get isinglass and our stout has lactose. We use honey in beers now and then as well."
