There is a Yerba Mate cold brew called Tereré[1], is very common in some countries of South America. Even more than the hot version in some places. I myself had it many times, sometimes mixed with lime juice, and even mixed with vodka
I can get the Yerba Mate leaf, but the cold brew I would need to make my self.
I was rather trying to see if there was any literature out there on if cold brewing limits or eliminates the PAH extraction.

It is just prohibitively expensive to ship individual products in.
Also there is no Amazon or its like here.
Hello back from Iceland!
Edit: You know, thinking about the amount of flights to and from Kevflavik, no matter if commercial airlines, or business jets doing a stopover there for refueling, I feel there is a niche to exploit. For something like a mini UPS/FedEX/DHL using that empty space, which has to be there?
I mean, open https://globe.adsbexchange.com/ point it to KEF, let it run for a day in some tab, and see how much air traffic from BOTH sides of the Atlantic goes there?
It isn't that there is difficulty actually transporting goods here.
It is that with transportation and import fees the products can, and often does, double in price. For cheaper things, it simply doesn't make financial sense to pay 4-5x the product price in fees.
In other words, if you have the leaf you can make either version.
Apparently the cold version has less PAH. Not sure if this is a practical concern but for what it's worth there's literature.

There's also the fact that regular Camellia sinensis tea has astringent properties, and people keep expecting that yerba mate, being a "herbal tea", might have similar effects, when in fact it doesn't.
Of course, as parent stated, many people never experience such effects. YMMV.
