It came with a few nesting pieces going from a k cup style, fine mesh for instant coffee, and a larger cup for other things I'm not certain of.
The instant coffee mesh on it makes the water stay around the tea long enough for a pretty nice brew. If you add slightly more tea than needed, you can fill a cup with ice for perfect ice tea.
Same. I usually keep a couple sealed bags for an individual cup in my pack, so If I get the chance away from home, I can have some of the good stuff.
It's gotten kind of expensive near me though, I need to find somewhere I can buy bulk loose tea.
I've been working at reducing my caffeine intake off and on for a bit. And thought I'd share a similar thing that I recently discovered. My wife got me a tea advent calendar from Adagio for the holiday and one of them was called "chicoriccino". It's a chicory-based coffee alternative with caffeine only from cocoa nibs.
Good flavor, though I'd never claim it's a "coffee replacement", just a beverage with a similar flavor category (like apples and nectarines). The big game changer for me was discovering that it brews very nicely in my overly-fancy drip machine and at the same ratios as coffee. So, I can just use my regular coffee scoop and get a nice, no-effort brew. Definitely recommended for anyone who likes coffee-like things.
Frankly, asides from supporting local business, there isn't much reason not to get tea from online specialty purveyors these days. It's not terribly expensive to ship the stuff.
Lately? Chess. I've been playing a little bit every day, and I find it so relaxing and calming. I use chess puzzles on my phone to put me to sleep every night.
