I want to start drinking tea more instead of coffee, I really like matcha tea but whenever I’ve had it it was with milk, but I want to drink more water and want to know if I can mix water and matcha tea?
Also I have a cold brew coffee maker, could I put the powder in the filter as I submerge it? How long would it last in the fridge (assuming I can)?
Nope. Matcha is meant to be ground fine enough such that it suspends in your liquid and is drinkable without filtering.
Sencha or any other green tea can be cold brewed. I’ve never done it myself, but pretty sure you just throw tea in some water and let it sit for a while. I’ve never done it myself, so just look up “cold brew green tea.” Granted, this will only be like matcha in flavor and not in mouthfeel. Furthermore, if you plan on adding milk, this is probably not the best route to take since green tea is generally much weaker than matcha, so adding milk eliminates any semblance of flavor from the tea.
Yep
The matcha will settle out if you let it sit. However, you can just shake it up again and then drink it after letting it sit.
