I would like deeped my know-how about bordeaux
Yes, the best way is to visit the châteaux in Bordeaux! and then all becomes clear particularly if you have someone who knows the region to take you around. The best time to visit is the early Summer or Autumn (after the harvest which is usually beginning of October (depending on the year of course!). et me know and I will organise you an itinerary! It is much better than reading books and less expensive than buying the wine once you are here. Enjoy!
Reblogged this on SIP Wine Blog – Bordeaux and commented:
Are YOU ready to run a gustative Marathon? The 9th version of this wonderful tasting open to everyone takes place on Saturday 17th May. There are organised dinners that evening too at some of our most beautiful châteaux with a range of wines of older vintages from a good spread of top classed growths (not just the host château). Some are already sold out but some still have availability. Château Olivier is stunning and not far from Bordeaux. Transport is provided from central Bordeaux. The only problem is knowing how to pace yourself on this gustative Marathon with so many fine wines to appreciate!
