Steve: What everyone means by "summer" colognes is colognes with a more citrus scent. Examples would be: Aqua de Parma, D&G Masculine, ect... As for "winter" colognes i would guess this means more woodsy or soapy scents. As for a "winter" scents, i was out shopping for colognes a few weeks ago and after sampling Creed, not seeing what the hype is about (It's not THAT great); the saleslady at Barney's suggested Gendarme. For those not familiar, it smells like soap, which is quite refeshing and different than most other colognes. I definatly plan on buying this in the future. For the past winter i wore Gucci Envy almost exclusively, which has a very woodsy scent.
