Our enjoyment of summer white wines increases every year. Until recently, our palates preferred Sauvignon Blanc and Pinot Gris/Grigio. But these days, we also appreciate the refreshing, wallet-friendly Turbiana grape from Lugana, Italy and Marsanne from here in Washington state. Most importantly, there are so many wonderful summer white wines. For example, here are 25 that we have enjoyed from Washington, Oregon, British Columbia, Italy, France, South Africa and New Zealand. Most of them are everyday, good-value porch pounders or deck wines, but a few shine with an elegant meal.
