I used to be very organized and systematic in how I kept track of my inventory but then it became a pain in the a@@. Now, I just make sure to tag each cigar with a date (either by writing the date on the cello) or putting a little sticker with the date on the label (that can easily be removed). The only thing I definitely like to know when I smoke a cigar is the age. Other than that, I try to make it as easy of a process as possible.
