Every 7 points of water qual gives me like +$1.8/bottle on my vanilla extract worth. I would want (roughly) more than Q20 water for it to be worth producing my own, preferably approaching 30. If I use 10m water per day, that's like $1.5m/day for it, I can compare that against how expensive it would be to build my own well and dedicated beverage plant and large R&D facility. I think that getting up and running would take me way over a week's worth of water costs...but then, my water demands will be going up as well. Also I think my break-even point is +$0.01 per unit of water per quality point. So producing cheap-ass Q0 water is not a bad idea...it's just ugly because I lose my edge in the market (high Q looks nice).
Also I currently spend $3.75/bottle or something on water alone. Which...okay, honestly? That's trivial. 1/25th of my final price.
Right then. As soon as I'm spending $10m/day on water, I'm going to drop beverage research (I only use it for better strawberry ice cream anyway) and flip it over to water research, and make a lifetime's worth of strawberry concentrate while I build my enormous well. I'll have to see how it goes. I am a little worried about limited real estate though. I mean...I'm going to be building a pasture soon and then start butchering my own goods, and I already have uh, plantation, orchard, food, bakery, dairy, ice cream.
