Both, plus rose.
A lot of good white out there, outside of the standard "this is what is popular and this is what you should drink" profiles. Also, a lot that people serve/drink way too cold (and a lot of red served too warm).
In fact, this evening I'll be at a little wine club release party where a new Vin Gris will be introduced - this vintage is Grenache, Petite Sirah and Zinfandel. The previous vintages have made for great summer wines.
Overall, I'm probably close to 50/50.
