I use only Sam Adams, and Sierra Nevada bottles.. I tried Amstel and Heineken bottles and can say for sure they are no good.. I prefer the Sierra Nevada bottles because they fit on the bottom shelf of the fridge better, and they make one heck of a beer!! BTW, my LHBS wants13.99 for a case of 12 oz bottles empty, and I can get a case of SN for 22.99 full.. That makes the case of beer only 9.00!!
