Teavolve, known best for its diverse hot alchemy selections, crossed over to the icy side with its sweet tea. Now we here in Baltimore don't take too kindly to what Southerners call "sweet tea." It's just sugar water to us, doing a little diabetic tango with our bloodstream. But we were truly surprised, if not stunned, by the lovely elixir served up by Teavolve one hot summer day. The sweetness swirled beautifully with a complicated blend of fruits and tea leaves in a tall, sweaty glass.
