I bought the perfect bullseye of a fresh tuna tenderloin today, and I thought this sashimi deserves a premium sake. I couldn't find a premium sake (central gulf Florida), and only one japanese brand, which I bought. (Fu-Ki). I found 4 California brands. I don't recall rice being a cash crop in the Napa Valley. Can someone enlighten me as to how to go about buying a magnum of premium japanese sake? And are these CA versions passable?
