I started brewing in mid January and have been sourcing my bottles from Sam Adams 12 packs. The first spin I gave them in the dishwasher heated the bottles and made the labels just slide off when removing. Only a few labels actually came off in the machine, be careful not to clog your dishwasher drain with labels, it will make a mess. I didnt use a heated dry either in fear the glue would just re-adhere.
