I often write about the variety of styles of Chardonnay and how our individual preferences influence our opinion of the wine. It is certainly good that we have choices. I do not assign a numerical rating to white wines but I hope that my description of the wines is more useful than a number.
My local Costco just started carrying a few new Chardonnays including Le Bruniche Chardonnay di Toscana, This wine from Italy is totally unoaked, so it is tart, acidic and dry with flavors of lemon, peach and a little minerality. This wine is too tart for me but if you are a fan of French Chablis, this is a viable, less expensive alternative. The wine has 12.5% alcohol and sells for $11.99 at Costco.
