Bring the wine, shallot, bay leaf, sugar, 1/2 teaspoon salt and 1/4 teaspoon pepper to a simmer in a skillet over medium-high heat; cook until reduced to about 2 tablespoons, 8 to 10 minutes. Remove from the heat and discard the bay leaf. Whisk in the butter and 1 teaspoon water until smooth.
Combine the lettuce, hazelnuts and herbs in a large bowl. Add the warm dressing and toss to coat. Season with salt and pepper and serve immediately.
