No real appreciable changes in wine type with the change of seasons for me, though with beer there is a definite change: as soon as the weather cools down, I stop buying beer. That said, the start of fall is synonymous with home winemaking for me. Towards the end of September I get really busy with making my homemade wines from grapes, and I do it with very minimal equipment.
I very rarely drink dessert wines, but I will have icewine, usually no more than once a year, and usually around Christmas. Other than that, it's the same mix of whites, reds and the occasional sparkler for me, no matter what the season.
