Brewery Bio - Mad Squirrel Brewery


First established in 2010 by directors Greg Blesson and Jason Duncan-Anderson, Mad Squirrel is a forward-thinking brewery that has continued to evolve and develop over the last 10+ years to produce some of the finest tasting craft beer the market has to offer. It is now one of the leading breweries in the South East of England and you'll find their beers across the trendiest bars and pubs in London and the Home Counties as well as here at the Bier Company! Find out more about the Mad Squirrel story and why we love working with them in our Brewery Bio. 

About Mad Squirrel Brewery

Greg and Jason started their craft brewing journey in Unit 24 Boxted Farm, Potten End in 2010. Producing around 50,000 litres initially, the brewery began life as a Red Squirrel rather than a mad one! They were focused on making traditional British cask ales to supply to the local village pubs and bars but oh did they have big ambitions!

Just one year later, Red Squirrel had been awarded the coveted CAMRA Hertfordshire Beer of the year award with their delectable London Porter (5%). After winning the award for a second consecutive year, Red Squirrel Brewery saw a boom in sales and their award-winning brews were becoming regular features in bars and pubs in and around London.

With success brought expansion and in 2013 Red Squirrel opened their first town centre outlet: The Brewery Shop in Chesham. In fact, The Brewery Shop proved to be so popular that over the following couple of years, Red Squirrel expanded to open four more branches in towns across Hertfordshire and Buckinghamshire. Production also increased to an impressive 250,000 litres and was no longer confined to the traditional British cask ales and now included contemporary IPAs, wheat beers, and lagers. 

By 2017, the time was right to move away from the traditional Red Squirrel brand to better reflect the diversified range of unique crafts beers. The new Mad Squirrel branding was unveiled alongside a move to a much bigger, bespoke brewery that was able to handle the whole brewing and bottling process from start to finish. With this move saw increased innovation and creation and in 2019 Mad Squirrel’s flagship $UMO (4.7%) American Pale Ale took the market by storm, accounting for 30% of all Mad Squirrels beer production. By 2020 Mad Squirrel was producing a staggering 1 million litres of unique craft beer. 

Move forward a couple of years and this contemporary, forward-thinking brewery now boasts a chain of seven Mad Squirrel Tap & Bottle Shops across towns in Hertfordshire and Buckinghamshire. They focus on natural, unfiltered, flavoursome craft beers and sell their amazing beers to customers across the country. $UMO now forms one of seven core beers produced by Mad Squirrel. Also included in the range is punchy ‘ROADKILL’; a 6.5% ABV New England IPA and the sessionable, 3.8% ABV, Gluten-Free Pale Ale that goes by the name of ‘HOPFEST’. Alongside the core range you’ll find limited releases, occasional regular returning favourites and heritage cask beers so there’s something for everyone to enjoy. 

Why we love working with Mad Squirrel Brewery

We love that Mad Squirrel is a craft brewery that has continued to evolve, develop and innovate over the past 10 years to produce a range of stunning beers. They have an inquisitive and creative approach to flavour which has allowed them to produce a fabulous range of contemporary beers that put bold, pure flavour at the forefront of every drink. 

We also love that they are influenced by modern, hop forward recipes that use only natural ingredients. Their beers are unfiltered and unpasteurised giving them even more full-bodied deliciousness. In fact, we love them so much that they are responsible for brewing Bier Company exclusive; Monkey Tree, a refreshing 5% ABV Kolsch lager.
