I don't remove the labels, I quite like leaving them on. Maybe it is because I live in Italy and like to see an English ale label on my bottles. Also, as sad as it may seem, quite a few bottles I have, bring back a few memories of the parties I was at or who bought them. One of my good friends would always bring over from the UK 6 or so bottles of decent beer, who unfortunately died late last year, so these bottles have some good memories of him.
In some ways, I would like to make my own labels, but think it is too much of a faff, unless I label say about a dozen to take to people etc., otherwise the bottles are stuck in my garage and only see the light of the day when I sup one or two.
