At a tasting of very old pedro ximenez this week there was an interesting discussion of the citrus aromas and flavours of some of the wines and someone came up with this brilliant comparison: the concentrated, bitter but orangey smell of your hands after peeling an orange. Have just peeled an orange and the descriptor is spot on (from memory at least, I am short of 80 year old PX to compare it with).

The orange is delicious too.
