This has both sinew and flesh, with taut dried red currant, blackberry and plum skin notes that are forced to expand outward as the core of black tea, charcoal, plum paste and dark humus fills in quickly behind them. The charcoal-tinged grip carries the finish, with more bass than treble at first, but there’s perfume here as well. Seriously long and the most overlooked of the truly great vintages here. *Ranked #6 in Top 100 Wines of 1991* (JM, Web—2014)  (11/2014)

Mineral and blueberry skin and flowers on the nose. It’s full-bodied with minerals and silky tannins. Dusty and very pretty. Refined finish.  (3/2012)

Deep and clean in color, the bouquet is quintessentially Château Margaux with blackberry, potpourri, cedar and violets. It has wonderful clarity. The palate is medium-bodied, fresh as a daisy on the entry with a killer line of acidity that offsets those vibrant black and red fruits. There is energy here, vivacity, as if this Château Margaux suddenly realized its true potential after all these years. (NM)  (10/2016)

The 1988 Château Margaux is a wine that I have encountered three or four times, most recently in May 2016 when it shone. Now at 30-years old it is still a lovely mature First Growth that gives so much pleasure. The nose is complex and well defined with black fruit, potpourri, incense and cedar, unfolding all the time in the glass. The palate is fresh from the start thanks to the fine line of acidity. Interestingly, this ex-château bottle felt a little more mature than the one that I purchased from a UK cellar, a little more spice and quite ferrous towards the finish. Like many 1988s, it is a wine that belongs on the dinner table than being analyzed on its own, but it is still a very fine Château Margaux now probably at the peak of its maturity. (NM)  (5/2018)
