I mean, you didn't include anything like tea, so it's kinda just easy. Fizzy, calorie-pumped, nutritionless, cheap-dopamine-providing, overpriced and overpackaged water is pretty low hanging fruit.
Water is the goat but have you ever jad a soda pop made botanically? Modern soda is just synth flavors and sugar, but it used to be flavored with actual spices. It's harder to find, but if you can find a truly classic soda brand it absolutely slaps modern corn syrup shit out of the universe
Imagine tasting cola, except it actually has a deep flavor palette and isn't cloyingly sweetened subsidized corn liquid
I drink 50% regular water, 50% herbal teas. Never drank sodas, if you're not used to them they taste far too sweet. I used to drink a lot of coffee, but I have quit caffeine completely, with 1 exception. I drink 1 cup of coffee the day after my night shifts, because this helps me feel ok that day. If you don't drink coffee regularly you notice two things when you do: 1. it's very very bitter. 2. the effect of caffeine is really quite strong. I feel like I'm on drugs that day. After quitting coffee I got a little bit bored with just water, I missed drinking something warm, so I started with herbal teas. I now have a large collection of herbs and I started to appreciate all these different tastes.
I’d personally place tea on S and water on A. Tea is far too versatile. Water is great but tea hydrates just as much and has the potential to be much much more.
I'd push water down to C or D level because I'm not sure what they put in this shit where I live, and I'd push low-alcoholic beer to S tier. It's how they did it in the old days and it carried us all into the future.
Water drinkers are so smug. So proud to be so boring that they drink only something that tastes of nothing. Unless you're absolutely parched and/or it's scorching outside, literally anything else that actually has a flavor is better.
