Monkey Wrench is brewed by the Daleside Brewery located somewhere in England. The label on the bottle describes it as "dark and beautifully smooth" while according to the Daleside's web page, it is a "strong, smooth, malty ale with a touch of sweetness". It was smooth alright, whatever that means, but I wouldn't call it "strong" and I didn't think it was sweet at all. It is a good beer, nevertheless, but I would like it better if it had a stronger aroma.
Daleside has a peculiar, poorly written and designed web page. If you look under "Bottled beers", you won't find the Monkey Wrench, but if you Google for it, the link I put above comes up. Why is it that only seldom does a brewery have a decent webpage?
