However, my personal record for a self-indulgent day was a days tour of wineries in South Africa.
The first one had about half a dozen reds, and a few different port-style ones.
We tried them all. We set off for the next winery, and tried all seven or so wines, including the worlds only Sparkling Pinotage, of which more later.
Two down, eight or so to go. By now it was not yet 11 a.m. The day degenerated from that point...
I hasten to add that we were being driven. And we got comprehensively slaughtered

Oh - the fizzy Pinotage.
