Been a while since being in here, just got back online today. Since i just moved again, i have to buy everything again. I had my own set up plus mr beer. They say we can use plastic PET bottles and reuse the caps. I got an 18 pack of coors light, 16 ounce brown plastic bottles, can i use them to bottle my beer? Are they PET plastic? I like them better, lighter and more convenient. Any advice will be appreciated. Thanks.
