The image here shows a nice lot of 1953 Cheval Blanc offered by an auctioneer in (I think) December 2015.
The discrepancy in the size and shape of the bottles is alarming, though it can and does vary with old bottlings. It’s rarely clear-cut.
In particular, the tall bottle at far right tapers from the neck to the base.
This bottle shape is something that you see with overpriced and overambitious New World efforts. It’s not something that you see with 65-year old clarets.
It also has the cleanest label here, which appears to be peeling off.
And the capsule is different to the other bottles.
Funny that, ain’t it…?
