Some commentators have been suggesting that there are now too many breweries in a slowly declining market. There's probably some truth in that, but I don't get the impression that was the case here. Sue has said the pleasure of brewing has gone after the departure of her co-founder, Gareth Matthews, whose creativity she has sorely missed. That loss, coupled with a change of premises, means that she no longer wants to run the business herself, but she is open to offers to buy it "so it could live on".
It's certainly a pity to lose a distinctive presence on the local beer scene, so you've always fancied running your own brewery, this may be your big chance.
