Our storyA new chapter, with history
A local family business: from a microbrewery by the canal in Mexborough to a purpose-built brewery at Sandtoft, relaunching in 2026.

01Where it started
Don Valley Brewery started in a small microbrewery in Mexborough, next to the Don navigation. Gongoozler, the stout, is named for that canal: a gongoozler is someone who stands and watches the boats go by.
It was too small, and in the wrong spot to grow. So the brewery moved to Sandtoft and built a purpose-built brewhouse, with conical fermenters, conditioning tanks, a canning machine and bottling kit.
The move came with new names. Most of the beers are named after a song, for good music and good times.
