About
Alexis Jones started up Mad Dog Brewing Co Ltd in October 2014 brewing from his kitchen at home. Closure of the brewery was imminent in early 2020, but later in the year the brewery was taken over whilst re-employing the former director as head brewer. Then located on a small industrial unit in Penperlleni.

In February 2022 we moved the brewery from our small unit in Penperlleni in to a larger, more dynamic space in the heart of Cardiff city centre. The move enables us to brew in larger quantities, and with the aid of some brand new equipment, hone in on our brewing processes to drive the quality of our beers forward!

In the same month, we opened our flagship taproom at the same venue as the brewery, meaning that we now have the perfect spot to deliver our beers at their freshest and tastiest!we are brewing on a modest 6bbl kit with 6 fermentation vessels. With Alexis leading the brew exploration, the team remains small and close knit each pitching in to help the other.

Mad Dog Brewery strives to produce an eclectic range of top quality, exciting beers from sour pales to hefty imperial stouts and everything in between. Utilising our fantastic Welsh water and the very best ingredients, we are able to
produce beers of outstanding quality to satisfy even the most adventurous and inquisitive beer aficionado.

Shiny clear medium amber colour, mid-sized frothy off-white to white head, dissipates slowly. Aroma light toasted malt, grain, pine-apple, biscuit. Taste medium sweet and bitter, malty, grainy, fruity, bit toffee. Dry bittersweet aftertaste, malty and husky notes, lingering orange pith. Light body, watery texture, average carbonation, though only 3.8% it's really a full flavored ale, very nice.

Cask half-pint, hand-pulled at The Bailey Head, Oswestry Shropshire on 27th Nov 2018. Black bodied with a good level blanket of tanned foam. Malty molasses rule the nose and taste, sweet and interesting with some light Christmas spiciness in both the aroma and flavour. Nice.
