I had the best sake I have ever had at Koi (NYC) about a year ago. It was an expensive bottle (about $65-85) and was unfiltered. We returned there not even a month later, and the waitress thought she had the right bottle; but it was far from it (very disappointing because she had no idea what I was talking about and actually brought a filtered sake to the table). Also, I know that my 'dream' sake had hints of persimmon in it. I cannot remember the name for the life of me and it was one of the sweetest, most aromatic tasting things I have ever ingested. I have been trying to chase it ever since.
Any suggestions for what this sake may have been? Or, to make it easier, can one recommed a cheaper version that may be similar to the above?
