Over-ripe oranges, strong bitter marmalade and hot-buttered toast initially, then hints of some more exotic fruit (perhaps fresh pineapple or passionfruit? Wine cask-induced?). Tinned peach syrup. Turfy phenolics are smouldering in the background. Becomes more citrussy with a few minutes in the glass, running the gamut from the previously-mentioned oranges, through Cointreau, then lemon sherberts, grapefruit, and lemon cheescake. Continues to evolve over time, which is always a good sign.
