Suitable for Vegans!


Over the past year or so we’ve found ourselves being asked one particular question by customers and beer drinkers alike and that’s whether or not our beers are suitable for vegans? A question that we’ve never been able to give a straightforward answer to… up until now that is!


To help explain, as a brewery that’s now in its 26th year of existence, here’s a brief history of our approach to brewing and packaging beer.  We’ve used Isinglass (a kind of gelatin obtained from fish) as a processing aid to fine our beers since day one. Stretching back decades, our beers have always been designed to be served (style-dependent) without a haze and the use of Isinglass has been key to this – especially when it comes to our cask beers. It’s a process that’s been common practice in the UK for over a hundred years.


Up until 2015, aside from a small, relatively short-lived venture into the bottled beer market, everything we brewed went into cask. We then bought our first canning line, becoming one of the first small / independent breweries to do so and set about ensuring that the beers we launched in can (and keg) resembled the appearance (in terms of clarity) of those served through a hand pump. We invested in brand new conditioning vessels and bright beer tanks, along with a filtration system to help remove unwanted yeast and proteins that exist naturally as part of the brewing, fermentation and conditioning processes. We also, to begin with, used Isinglass at the end of the conditioning process to drop out as much of the spent yeast as possible prior to filtering. This was to help with making sure the filter didn’t become blocked, as well as ensuring the beer’s stability suitable to the package type.


Over the past four years we’ve further invested in a higher spec filtration system and refined our practices, which resulted in us no longer using Isinglass as part of our can and keg packaging process towards the end of 2017. We then turned our attention to our cask beers in 2018 and spent a large part of last year researching and trialling different methods to find the best option for us to be able to remove Isinglass from our cask beers and therefore all of our beers entirely.


The results are in and we’re delighted to advise that we’ve achieved this and, for the past couple of months, everything we have produced has not involved the use of Isinglass and has been suitable for vegans and vegetarians alike.


What have we done to achieve this? Essentially, we’ve switched to a vegan-friendly fining agent called Super F. This ensures that our cask beers (style and recipe depending) will continue to have the same appearance they have since the brewery was founded in 1993. That said, the only small difference that may become noticeable to landlords and publicans is our beers might need a little extra time on stillage before they drop completely bright. In some circumstances, certain beers may carry a slight haze as a result of the switch in finings, despite additional stillaging, but we see this as a small price to pay in opening up our beers to a wider audience.


We’ve delayed sharing this news until now in order to allow for a period of transition away from using Isinglass to take place, so drinkers can be 100% confident that what they are drinking is vegan friendly. With that in mind, we’re advising that any of our cask beers that carry a gyle number that begins with 18xxx be treated as being unsuitable for vegans. Any beer that carries a gyle that starts with 19xxx (19001 being the first) is 100% vegan friendly.


To assist those serving and drinking our beers, this information will be shown on all of our cask stickers going forwards, as well as being shared on the reverse side of the pump clips we supply with our beers.




The three beers that make up our core range in cans (24/7, Baby-Faced Assassin and Yankee) are all also 100% suitable for vegans and have been for some time. Unfortunately, with the cans having been printed prior to us being ready to make this announcement, there isn’t currently any information stating this within the current design. This will be addressed the next time we place an order for more to be printed.

Over the past year or so we’ve found ourselves being asked one particular question by customers and beer drinkers alike and that’s whether or not our beers are suitable for vegans? A question that we’ve never been able to give a straightforward answer to… up until now that is!

This is a public service announcement: Today we brewed the first of three new beers that’ll be coming your way in both cask and keg in January 🍺🍺🍺

2018 has been an incredibly exciting year for Rooster’s and 2019 promises to be no different...

Where has this year gone?! It doesn’t seem like two minutes ago that we launched our 25th Anniversary Collaboration Project, but here it is, the last of the beers is being released next week & we’re going out with a juicy, cryo-hopped IPA brewed with the lovely folk from @fourpure 🍻

We’re delighted to have won a British Guild of Beer Writers award last night for the magazine we put together as part of our 25th Anniversary celebrations. Props to all the winners of the night’s other awards, it was great to be in the company of so many skilled & passionate beery people 🍻

We had a blast pouring Howl and High Tea alongside friends from some of our favourite Yorkshire breweries this weekend as part of @207beerweek; soaking up the amazing beer scene they have going on in Portland along the way. Thanks for hosting such a great festival @mainebrewers! 🍻

‪Amazing to see Baby-Faced Assassin being poured at @slabportland, especially amongst such an incredible line-up of beers. Outrageously good pizza too! ‬

Coming to a November near you soon, three beers from two collaborations with our friends from @amundsenbryggeri and @freewheelbrew 🙌🏻 🍻

Keep an eye out for a small(ish) addition to the latest batch of Yankee pump clips we’ve had printed that’ll soon be adorning hand pumps at quality outlets across Yorkshire & beyond #productoftheyear 🏆🍻

Thanks to everyone who nominated us. We were delighted to learn we'd been shortlisted for this award a few weeks ago, but to actually win it is amazing. Hats off to the whole of our team & well played Yankee - not a bad way to celebrate 25 years since first being brewed! 🏆 🍻

We had a blast brewing with our good friends from @greencheekbeer a couple of weeks ago. The result is Pecking Order, a juicy pale ale that includes a cheeky little addition of dried orange peel from oranges grown, picked, zested, dried & smuggled into the country by Evan & Brian. Catch it launching in both cask and keg at @10devonshirepl on the 20th and then at our last brewery taproom social on Saturday 22nd! 🍻

We’re all set for @leedsbeerfest 🙌🏻 Come & find us to quench your pale ale / brut pils / lemon radler / Turkish Delight stout / pineapple & grapefruit IPA / cucumber pale ale / Rocky Mountain IPA / IPA-Lager hybrid / American wheat beer thirst 👍🏻🍻

It has come to our attention that the cans of One Trick Pony, our recently released Rose Lemonade sour, carry some information on the labels regarding the beer’s suitability for vegans, which is incorrect.

Fancy a few light ales direct from the source, served by the brewers? We're opening our doors for the first time as a tap room on Saturday February 24th between 12pm and 6pm.

It’s not every day that a brewery turns twenty-five, so we’ve decided to celebrate by brewing a bunch of beers with some of our favourite brewers and breweries across 2018.

We've teamed up with our friends at Taylors of Harrogate to develop a brand new black coffee IPA called Wake-Up Call.

This year's open day will take place on Saturday July 29th and we'll once again be joined by DJ Tony Safari, as well as Mac Daddies, Andy Annat's Crackerjack BBQ and Karkli's Chompmaster, Kumar.

We're delighted to share the news that Rooster's came away with a gold, silver and bronze medal at the 2017 International Brewing Awards.

Late last year we brewed a beer called Howl, which was a 6.8% imperial stout that was conditioned on rum barrel oak and released a cask-only limited edition beer in the run up to Christmas. What we didn’t tell anyone was that we squirreled 5 BBLs of the original beer away...

Rooster’s scooped five awards at the SIBA North East Beer Competition, which was held in York on September 14th.
