How do you cold brew bro?

So Runa is great because we have the Ready-To-Drink bottles of our energized great Runa in six flavors, but sometimes a lot of people ask me about the amount of caffeine or sugar in the bottles (if the lime and guava unsweetened aren't around them).  So if caffeine is an issue for people - which for a lot of people it is I always bring up our original wonderful hot "tea" bag Runa.  These flavors include traditional guayusa (almost matches a green tea flavor - but it's just the flavor of the tree leaf GUAYUSA why-oosa itself - remember no tannin! super smooth), cinnamon lemongrass, mint guayusa and ginger-citrus guayusa.
These all vary in caffeine each box with traditional as the highest around 34 mg and cinnamon as the lowest caffeine around 19 mg.
I know a lot of people like to make their own iced tea in the summer because you can control sugar, caffeine, taste and make a giant batch.  I suggest doing this with Runa because yes you can hot brew it and stick it in the fridge or you can COLD BREW it! Whooo! And because the GUAYUSA tree leaf doesn't have any tannis, the longer you steep the tea the sweeter it actually gets - naturally! I am actually cold brewing ginger-citrus as we speak.
I would love to hear people thoughts and ideas about cold brewing.  I read online about leaving depending on the type of tea, the bags or loose leaf in the fridge for about ten hours, but I've been doing two tea bags in a cold glass of water for about 15 minutes and it seems to be working okay.  But I have never cold brewed before!
