I have not had that much 1975 Bordeaux. When I first started buying wine, the 1978s and 1979s were on store shelves. Then, when 1982 Bordeaux futures came out, I pretty much stopped buying earlier vintages and concentrated my pretty scarce at the time wine money to be spent on Bordeaux on 1982s.
But, the two 1975s I have had a few times are Pichon Lalande and Leoville las Cases. I loved both of them - with time. For me, the 1986s are getting really good right about now. Yes, they have the structure of the 1975s, but they have a lot more fruit and now are almost 40 years old.
