There are Wine Tourism Activities in and around RONDA. ""Enoturismo""
Look at the RONDA TURISMO local tourism web site and specifically under ENOLOGY and GASTRONOMY and you can get a lot of information about the local wine and of course the producers. Several will be pleased to show you their vineyard etc. There is a list including Bodega Joaquin Fernandez as mentioned above so you can not only see where they are situated but also try to make contact with selected ones.
on this page just click on each producer's name at the top of the page - WINERIES- and you can see more information =
And on the link (LA SANGRE DE RONDA) you see more information about the Museum of Wine in Ronda.
Ronda red wines are very full and pleasant - very good with all meats in my experience.
