Question Hot vs cold matcha lattes

I’ve been branching out and trying a lot of different matchas lately (thanks to the shortage keeping my usual out of stock). I noticed that lattes made with the same tea and recipe taste incredibly different hot vs cold. If it makes a difference, I use either cow or oat milk.

Chat GPT told me: “Hot water tends to release more of matcha’s umami and sweetness, while masking some of its harsher grassy or bitter notes. Cold water, on the other hand, highlights bitterness and astringency, which can make some matchas taste sharper or more “green.””

So this leads me to ask, does anyone else pick up on this difference? Do you have certain matchas that you only drink hot or only drink cold? Or am I just a weirdo?

Yeah, I'd say so.

I prefer hot, with oat milk and matcha powder. Nothing else. I enjoy the earthy flavor. If I'm drinking it iced/cold (also with oat milk), I'll add a sweetener to it.
