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.

Bo-Wow from Mad Dog Brewing Co.

5.2/10 — Appearance 6 Aroma 5 Flavor 5 Texture 6 Overall 5
330ml bottle: BB Dec 2018. Out of date when bought at the Sherman Theatre, Cardiff. They gave me a bottle of SNAFU Boom in exchange and removed all their stock of this (all the same batch). Anyway it poured a slightly hazy gold with a fast fading white head. Not great, it had an 'off' aroma and taste, like a dirty dish cloth had been used on the glass. Scored kindly and objectively.

330ml bottle; BB Nov 2019. Drank on 15th May 2019 in the bar of the Sherman Theatre, Cardiff before watching a play. Dirty brown body, beige topping. Strange but fine, veg like aroma and initial taste, turning slightly malty in nature and then hop bitter towards the end. Almost like it.

Thuis uit een halve liter fles in de tuin, na een fietstochtje van 35 km. Mooie donkere amber kleur, helaas geen schuim. Smaakt redelijk, licht bitter, maar is wel een beetje vlak. Geen topper.

Cask-conditioned at the Seven Stars, Bristol 11/2/2019. Golden with a thin, white, head. Tangerine and pineapple fruits, citrus hops, biscuity malts and a dryish finish. Enjoyable.

Bottle. Mitchell’s Wines, Sheffield. Deep, clear, cola brown. Head fully dissipates. Nose has cherry chocolate truffle. Steeped vine fruit. Hint of clove and cinnamon. Touch of anise. Taste is vinous and sweet. Some light roast bitterness. Medium body. Pretty smooth and slick on the palate. Low carbonation. Light fruity bitterness to finish. Enjoyed this way more than I expected to.

Thuis uit een fles (halve liter). Mooi zwart, weinig schuim. In aroma chocolade. Smaak helaas wat slap, maar al met al gezien de 4,5% een redelijke stout.

330ml bottle from Vinomondo, Conwy. Pours a murky golden amber, no head to speak of. Aroma is lactic sour, light cinnamon. Taste presents a very light carbonation, moderate sour, light cinnamon, would welcome more apple notes, light-bodied. It's fine, just lacks a bit of life.
