This is probably pretty irrelevant to most all of you, but....
I've been a label collector from the very start.. when my major professor (about 1968) suggested to me I soak off the labels of wines I liked so I could remember then. I've never forgiven Ken for that.
I have probably well over 100,000 labels, though recently they are not well curated. I know... I've been looking for a good 12-step program!!
Used to be they all had water-soluble glue and fell right off with a brief soak in water. But adhesive technology advanced. I give them a soak and then use a single-edge razor blade in a holder to peel them off. I can usually tell by feeling the label if it'll come off. Probably lose only about 1 in 25 labels. The Italian labels seem to be the worst.
Over the last year, I've noted there's been a change in adhesive technology. First noted it on the Ridge and DryCreekVnyd labels. Now I'm seeing it on more wineries. You use the razor to peel up the edge, then firmly grasp the label and pull hard. The label separates from the adhesive that sticks to the btl, and then you just pull the label right on off. Sometimes the label is printed on a foil backing, but not always.
But, anyway, it's a technological advance that I very much approve of.
For those of you that have questioned the weirdness of TomHill, this should be the final nail in that coffin.
