Bruce Murray and Diana Lyttle's Boundary Breaks is as good as it gets when it comes to affordable, drinkable Rieslings that are neither too cloyingly sweet nor searingly dry. The Ovid Line North cuvée (checking in at 1.9% residual sugar) drinks dryish, full and lush on the palate, and we hesitate to call it "entry level" because it's just way too good for that simple description.
