The bar is in the old workshop of the Denver Mill complex. The mighty Blackstone diesel engine that powered the mill is still in its original engine house and still in working condition. You can see some of the machinery which gives the bar its name. Voted local Cider Pub of the Year for 2019. There is no food available but there is a reciprocal agreement with the cafe next door that you can take beer into the cafe or food into the bar.
