Today in my rotation it was Calvin Klein Eternity aftershave followed by vintage Trumper Eau de Quinine.
Top notes of the aftershave are lavender, lemon, bergamot, and mandarin orange; middle notes are sage, juniper berries, basil, coriander, geranium, jasmine, orange blossom, lily, and lily-of-the-valley; and base notes are sandalwood, vetiver, musk, Brazilian rosewood, and amber.
The Trumper notes are variably described, depending on source, as mandarin or orange peel, lemon, bergamot, rosemary, herbs, gentian, cascia, and bitters (cascaarilla).
They have in common the citrus and herbal notes, and together they blend really well, with the floral notes of the aftershave balancing the bitters of the EdT.
