If you are a beer lover, the idea of running your own brewery might sound like the stuff of dreams. And it might seem like the perfect time to do it - an explosion of interest has seen craft breweries pop up in huge numbers in many parts of the world. But the industry is notoriously hard to crack. Expensive equipment, the space required for brewing, a need for big marketing budgets and fierce competition from other brands are all factors. Then there’s the hugely important, but rather subjective question of whether your beer actually tastes any good. Tamasin Ford speaks to three craft beer aficionados in the UK, USA and Brazil who all tried - and failed - to turn their hobby into a viable business. They talk about their hopes, hurdles and mistakes and whether the journey has affected their love for the amber nectar.
