Palo Cortado is a rare style of sherry with the aroma of an amontillado but the body and depth of an oloroso.
It sits between the two neighboring styles — the nose of one, the body of the other — so either of them covers half of it. Neither reaches the combination, which is why the style is rare and priced accordingly.
A lighter body under the same nutty nose, and the drink keeps the aroma and loses the weight, so stir it a touch less when you swap.
Body and depth match; the nose is rounder and the dry nutty edge is gone. The drink keeps its weight and reads softer.
An oxidative sherry keeps weeks in the fridge once opened, though it dulls over time.
