+1 Demeter Gingerale, slight but fun, with fizz and citrus on a ginger topnote (and not much else).
Also check out Roger et Gallet, Gingembre, my favorite ginger cologne.
Another fragrance with a very nice ginger note is Chillum by Abdessalaam.
Ginger is good.
My very favourite is Five O'clock Au Gingembre, but I have Declaration Cologne and Brit, want Envy, and like Origins Ginger Essence and Kenzo Homme Sport. L'Homme is pleasant but not all that interesting. DHS is not as good as the Cartier or the Kenzo.
