The brew, called Perro Tonot, is a sherry cask-aged amber ale, which comes in corked Champagne-style 750ml bottles.
It has been made using Maris Otter, Crystal, Black and Wheat malts, hopped with Pilgrim and Cascade before being aged in the Spanish sherry casks for six months.
Flavour profile
Perro Tonto, which is Spanish for 'silly dog', has aromas of sweet, dry fruits of raisins and rich Christmas cake, and aims to have a well-balanced, luxurious feel.
It is a tribute to the brewery's late dog, Useless Bloody Urchin (UBU) – pronounced 'OO-BOO', which led to the creation of one of the Purity regular beers – Pure UBU.
The beer is limited to just 900 bottles, which will each be individually numbered.
Immensely proud
Purity co-founder and managing director Paul Halsey said: “This year has been incredible for Purity and we are immensely proud of our record-breaking list of awards.
“A major part of our development over the past 11 years has been on how to achieve absolute consistency and pure quality throughout the business, and our limited edition beers are a great way of showcasing the skills of our brew team.
"We were delighted by the feedback we received for [variants] X & Gnarly in previous years and we love presenting our limited edition brews in 750ml bottles. It gives a real sense of occasion when you twist the cork on a fine barrel-aged beer."
“Perro Tonto is a stunning beer for our loyal puritans and it is great to pay homage to our former canine friend too – Salud amigo!”
Purity director of brewing Flo Vialan said: “These brews allow the team to experiment and truly showcase the talent and skill we have and I cannot wait to get mine open over Christmas.”
In an exciting year for the brewery, Purity’s ethic of "brewing with a conscience" has seen them retain their Made in the Midlands Sustainable Manufacturer of the Year title, while the growth of the brand and the quality of the beers has also seen the brewery achieve a record-breaking year of national and international award success.
