I think we might have had a similar topic, but it was a long time ago, and maybe it wasn't quite the same question.
I go on a minor binge when I visit Scotland every October, buying 8-10 bottles (now have to watch airline limits--NW Airlines supposedly only allows 5 litres). I buy sporadically through the rest of the year, normally a bottle at a time. I'm surprised to see I bought 31 bottles in 2006--didn't think it was that many--34 in 2005, 29 in 2004, and a mere 18 in 2003, which seems to be when my interest really started to pick up steam. I have 61 bottles inventoried before that, but I didn't start noting purchase date until late 2002. (Note lots among all these are empty--I have 82 still with contents, six actually open.) There probably weren't very many bottles before I started keeping inventory--I didn't get interested in whisky until after I first went to Scotland in '98, so it was probably 15-20 a year.
One so far in '07!
You didn't ask, but I opened 16 in '06, and at least 25 in '05--only started tracking that in Feb '05. Finished 14 in '06 and at least 19 in '05--yikes, I'm slowing down!
I'll bet most of these numbers are low compared to many of the lunatics around here.
Hmmm...I finished a bottle of Talisker 18 nine months before I opened it....
