Removing wine labels from bottles

Factual Questions
1

I’m trying to keep the labels for use in a wine tasting book I have.

But the technique I used on stamps on envelopes as a kid (immersion in water) doesn’t seem to work at all. The glue under the label is resistant to water, and all it does is stain the label.

Any ideas?

You know, to excuse myself from the perception of laziness, I thought this would be such an odd thing to do that it wouldn’t show up on a Google search, but your link has websites dedicated to the practice. Thanks.
