I found out there is a Kakulas near me, after however long not even knowing for some reason. Its actually pretty good, lot of interesting stock.

One thing it did have that Im not sure I have ever seen before is Yerba Mate, and its in big 1kg bags.

Yerba Mate @ Wikipedia

Its pretty good, tastes like a green tea, a bit more grassy, herbal and can be quite bitter if brewed too hot. Brewed colder it has more depth of flavour and even and interesting mouthfeel.

Caffeine levels seem to be similar to strong green tea, though a lot more mate is used per brewing so it can be quite strong.
