What Does "Bin" Refer To in Lindemans Wines?

[Innkeeper]

Not positive about the "b" in bin, but it is something like "basement or box identification number. It is used on wine lists in restaurants so that when customers order by bin number a. they and the waitperson don't have to pronounce the name of the wine, and b. so that the waitperson can go straight to where the wine is stored.

Lindemans just moves this concept to the name of their first line of wines, as it is a term that wine drinkers are familiar with. That's my theory anyway.
