Moor Beer is releasing three Double Stouts as the first instalment of its barrel ageing project from its Bermondsey Vault.

The Batallas Double Stouts, which are brewed in collaboration with Madrid-based brewery, La Quince, will initially be available exclusively from Moor Beer’s taprooms in Bristol and Bermondsey on draught and in 33cl cans.

The three varieties are from a single brew. The first is the original expression of the Double Stout, while the other two have spent much of this year maturing in rum and whisky barrels.

Justin Hawke, Moor Beer’s head brewer, said: “We have been barrel ageing for almost 10 years, but as many know, it is not only a time-consuming project but it also requires a lot of space. Our Bermondsey Vault has allowed us to up the ante and we are thrilled with the first results.

“We are firm believers that good beer should not be rushed. Having the opportunity to barrel age for a period of time has delivered natural beers that are full of flavour. This is a fantastic opportunity to see how the same brew can be influenced and enhanced in three different ways.

“The beers from the rum and whisky barrels have been enhanced by the flavours from wood and the spirit that was previously within. For instance, the whisky barrels provide a notable yet balanced peaty flavour that compliments the richness of the double stout.

“We collaborated with La Quince to brew this beer with our mutual friend Batallas. We all love dark beers full of flavour that are immensely drinkable. It was a pleasure to share our first Vault projects with friends like these.

“Other than holding a few kegs back for special events next year, our taprooms will be the only place to try these three beers. We are expecting a great turnout and lots of celebration in both cities.”
