I mostly try to drink water nowadays when i'm at home or at work, because it is H E A L T H Y or something like that.
My favorite beverages are in unranked order
Fritz-Kola, it's like normal coke but with lightly less sugary taste and thrice the caffeein content.
Emmi Cold Coffees. Unfortunately i can't drink them as often anymore due to my lactose issues, but they will always have a special place in my heart, in the past i was sometimes chugging three of those a day.
Almost all cocktails, but especially fruity ones, such as Maitai and Pina Colada
And of course, good, german beer. How could i not. mostly Pils and Kölsch,
I'm not a huge tea drinker, but at my old Job i LOVED the freshly brewed Cay from a nearby restaurant you would get with your Kebab menu.
In regards to hard alk i drink pretty much everything, but i prefer not to do it pure.
And to really Insult our local bartender
「Echo」 , i recently had a Whiskey cola out of a can
