Polenta and Brussels sprouts --- YUM. Lovely post, and the combination is really intriguing. I'm a huge Brussels fan (ever since I learned how to cook them properly). (found you via FoodBuzz, by the way)

For me, a boutique wine is often one that comes from a smaller production or an "out of the way" winery as Chez Us mentioned above. Seems that in Napa/Sonoma, boutique = expensive (based on my limited experience(. I expect a boutique wine to be delicious and/or unique, preferably both!
