You could do a tour of pubs based on black country breweries maybe?
Holdens have quite a few pubs in the area and Golden Glow is one of my favourites. Then you have Craddocks, Sadlers, Bathams, Enville and Black Country Ales.
Starting in Brierley Hill and moving onto Stourbridge is a good bet. Bathams at the Bull and Bladder/The Vine in Brierley Hill, move onto the Rose and Crown on the same street for Holdens (alternatively, the Shrubbery in Stourbridge).
Moving towards Stourbridge, you can then try the Windsor Castle Inn for Sadlers in Lye, then 5 minutes up the road to Stourbridge where you can have Craddocks at the Duke William and a number of pubs in Stourbridge stock Enville Ales which are as good as anything you could try around here. There are also Black Country Ales pubs in Halesowen, on the way to Stourbridge.
Edit, if you wanted to stay in Stourbridge, Bathams have 2 pubs there, the Unicorn and the Royal Exchange, which paired with the Shrubbery, could mean you don't have to move around too much.
