You can soak the bottle in hot water then fill the bottle with cold water and try peeling the label off. This doesn't always work. You can always keep the cork which will have the name of the winery , web address , and sometimes telephone number. Also at the Paper Place on North Lamar near Central Market they have a wine notebook were you can jot down all info about the wine. When all else fails go to Central Market and ask the guys in the wine dept.
