Looking at "Addresses" on FindMyPast, there is certainly a Wetmore Road in Burton on Trent - listed in 1881, 1901, 1911, 1921 and 1939. It must be where the breweries are - mention is made in 1881 of "Bass Buildings" and a lot of occupations are "Maltsters".

ADDED: AND if you look on Google Maps you will see that it is a very long road.
