Brew Monster started when 4 friends joined forces to bring together their combined skills as a brewer, an accountant, a sale manager and a designer, with the dream of building one of Wales' best independent breweries. By March 2017 we were in a position to register the company and start building the business. To fund the original brewhouse and working capital, we took personal loans and raised additional funds from friends and family. This allowed us to buy a 4 bbl (650 litre) brewhouse and take a 3 year lease on a premises in Cwmbran. The brewhouse was installed in September 2017, and on 27th October 2017 we had our official launch party.

At the end of July 2020 we reached the end of the 3 year lease on our Cwmbran premises. The unit had been our beloved home and headquarters for 3 years, but due to limited space (and an inflexible landlord) we were forced to look for new premises to move our brewhouse. We were fortunate to find a great location in Caerphilly town centre. Coincidentally we got the keys for our new premises at Unit 1, Lon Y Twyn, Caerphilly on 31st July 2020, the same day we said goodbye and handed back the keys to our Cwmbran unit.
