Tried water that sat in my kettle overnight and I think I've been ruining my morning cup
So I read somewhere that old water in the kettle can taste flat because it loses oxygen, and I figured that was just internet noise. But I tried it anyway, dumped out the leftover water from the night before and filled fresh from the tap, and used the same beans I always get from the place two blocks from my apartment. The cup tasted brighter, like the citrus note I could never really pick out before was suddenly right there. I did it three mornings in a row to make sure I wasn't just fooling myself, and every single time the fresh water cup beat the stale water cup. I even made my roommate do a blind taste test on day four and he picked the fresh water one without knowing which was which. It's such a small change that costs nothing, but now I refill the kettle every single night before bed so it's ready in the morning. I'm wondering if this is one of those things everyone already knows and I'm just late to the party, or if it's actually a real thing. Has anyone else noticed a difference with fresh water versus water that's been sitting?
A buddy of mine swore his coffee tasted off for weeks and blamed his grinder, then his beans, then the shop he buys from. Turns out he was filling the kettle once and letting it sit for days because he lives alone and only makes one cup. Switched to dumping it and refilling fresh every time and the weird dull taste went away pretty much right off. He also noticed his tea stopped smelling like nothing, which he had just gotten used to over the years. So it's not just you. Standing water goes flat because the air comes out of it over time, and there's less of it to pull the flavor out of the grounds. I keep my kettle half full at most now so I'm not reheating the same water all week.
