I realized, after reading your note, one of the bottles I had standing (to let the sediments settle out) in the basement was an '87 Les Cotes Sauvages, so I opened and decanted it. Lots of development, but, really, no signs of fatigue in evidence. Spicy, fresh nose, nice and firm in the mouth, with very engaging tannins, and nice long flavors. I think you'll enjoy it!
I noticed, elsewhere, you have an '88 Syrah, too. I'm not so sure how that might be; the late Summer/early Fall of '88 was on the torrid side, and things sweetened up fast without great depth of flavor. Will be interested to know how you find it. (Haven't had one for years, and don't have any left)
