Although I'd happily do without those irritating waxed capsules, Eric, I don't think the advent of smaller bottles of such things is all that bad an idea.
I mean the small, sampler-sized bottles, not the ones that are designed to go into curio cabinets or on knicknack shelves for display, forever remaining unopened.
When I went to western Canada some years ago I noticed that most liquor stores had lots of 50ml bottles, individually boxed, of Ice Wines, ranging in price from about $7 to $15Canadian.
I inquired about them and was told the original impetus was to capture a lot of the Japanese gift trade (it's traditional for Japanese tourists to bring back tons of gifts for folks back home). The bottles were an immediate success (even though some producers thought they were a PITA, they did them anyway because they couldn't ignore the sales).
Turned out, lots of people liked them because they were able to have a small sample of something they might not ordinarily buy in a 750ml bottle.
I thought for years that smart producers of specialty/dessert wines would be smart to develop smaller sizes. How many more people would purchase such wines if they were more readily available? I think quite a few.
When I was selling Castello di Brolio wines, they had a marvellous Vin Santo...but my company was bringing it in only in 750mls, and it was soooo difficult to sell. When we begged and pleaded for 357mls, the sales immediately and dramatically improved. If we had had an even smaller bottle, I suspect the retail sales would have improved even more. And more people would have been exposed to the wine. Which is a good thing.
