I have found it useful to set up a simple excel spreadsheet to record names of wines that I am trying.
This can be as simple or as complicated as you want to make it. I keep mine simple, 7 headings, as the following shows:
Name, Date, type, region, price, taste note, date --
Rodney Strong, 2003, Sauvignon blanc, Sonoma, $9.00, excellent, 9/28/2004
Invaluable for later reference.
