Thomas Twining started selling tea in London in 1706. His eponymous company has been doing it for 300 years, then. You’d think they know tea if anyone does. Here’s Twinings Green Tea:
Green? Brown? Golden brown? Tea-colored? Flax? Tannin? Purple? Polka-dotted?
Does that look green to you? I guess they specialize in black tea (which I bet isn’t black after brewing).
My quest for green “green tea” continues. I already found one: Kirkland Ito En Matcha Blend Japanese Green Tea from Amazon.

PS: If you don’t like green, you’ll find none of it inside my books.
PPS: The remains of Ulysses S. Grant and his wife are in a mausoleum referred to as Grant’s tomb. They are above ground, so technically they aren’t buried.

I’m in China, where the green tea is a yellowish green color, and drank
very weak. It is not in tea bags
Lauren, thanks for chiming in. My Ito En Matcha Blend is green at first, then yellow-green 4 minutes later.
