If you are more into tea, cold brew tea is also a thing and very nice. This actually works with most varieties of tea but is especially nice with white or green tea. Rooibos is also a nice one to try. Simply steep a jug of cold water with some tea in the fridge and leave it for 12 hours or so. Very refreshing and it typically has a sweeter/less bitter taste than normal tea. I don't add any sugar/honey so it's healthy too. But of course you can if you want.

I also drink coffee sometimes but mostly green tea these days. I get my tea from a Pakistani supermarket in Berlin that sells it in bricks of half a kilo. I drink about a liter of that in the morning. When I drink coffee, it's mostly at nice coffee shops. We're very spoiled with those in Berlin.
