Preface to the reader: If you don't have a microwave, but you still made the effort to join us on this amazing forum, I'm sorry, but this post isn't for you. No hard feelings? So, I stumbled across something when my mini-crock pot decided to give out on me. For a while I had been forced into making one bottle of juice at a time, so the water didn't ruin the label. I wasn't putting them in a plastic bag, just in the water. Then I decided to try microwaving some water in a plastic cup. I put the bottles' label on beforehand, so I had multiples in a zipper-type bag that comes in a box, but then I covered the mouth of the cup with the bag, and found that I could easily pull the bag in and out of the cup enough to reach the bottles. As long as you don't use water that's boiling from the microwave, you won't ruin the juice. This is also useful for fresh juices bought in a local B&M. It's best to give all the bottles a good shake before, during, and after the steeping. This makes sure that any separated ingredients mix well before they heat up and truly mix together. I've experienced phenomenal success with this method on a variety of flavors like custards, tobaccos, complex fruit blends, but I haven't had any cinnamon-like flavors to try it on... yet. The water stays hot for a good bit, but it's easy to pop it back into the microwave for however long. Obviously we need to take caution with hot water, and I take no liability for any injuries caused by hot water spilling and burning, maiming, or scalding anyone. Please be careful if you choose to try this steeping method. Thanks for reading this whole post, and not being a TL;DR. You stay classy, Underground Vapers.
