Preheat oven to 350℉. Line a baking sheet with parchment paper.
In a medium bowl, whisk together flours, cocoa, baking soda and salt.
In a separate large bowl, cream sugar and butter with an electric mixer until light and fluffy. Add eggs, one at a time, scraping down bowl as needed. Mix in zest and wine. Add flour mixture a little at a time, and then pistachios and chopped chocolate.
Form two flat logs about 12 x 2-1/2 inches on prepared baking sheet. Bake 25-30 minutes, until slightly firm.
Remove sheet from oven, and cool for 10 minutes. Reduce oven temperature to 300℉. Transfer logs to cutting board by lifting parchment, then slice logs into 3/4-inch slices. Line the baking sheet with new parchment and transfer biscotti, cut side down, onto the sheet. Bake until crisp, turning halfway through, about 10-15 minutes.
Cool completely on a wire rack.
