Yesterday I missed a turn and ended up having to drive by the Tower Liquor store near my apartment that I knew (thanks, Charlsie) carries sweet-tea-flavored vodka, so I figured that was a sign. I stopped in and picked up a bottle. There’s very little to say about it but YUM. This stuff is seriously good.
The serving suggestion is vodka & water (half and half) with a twist of lemon. That’s yummy. So is an Arnold Palmer with Firefly substituted for the sweet tea. I had heard that you really can’t taste the alcohol, which is not really true. You can definitely taste it, it’s just very, very subtle… although I guess how subtle depends on the ratio.
Bottom line? Buy this stuff if you like sweet tea and getting drunk.
Update: Because this seems to have become a pretty popular entry on account of people looking for reviews, I thought I would point out the more thorough review of Firefly sweet tea vodka that I did for FanHouse.

I just added the “Arnold Palmer” to drinkoftheweek.com. This is an AMAZING drink!
1/2 Sweet Tea flavored Firefly vodka (70 proof)
1/2 lemonade (any brand)
Throw it on some rocks.
Tastes just like southern style sweat tea! I’s RIDICULOUS!

Had firefly sweet tea vodka in Charleston,SC the beginning of Sept. Loved it!! It is one of my favorite drinks. I’m in VA and was told it wasn’t sold here. Have since found out that it is, but you have to catch the shipment or you won’t get it. Also good with sweet n sour, a little triple sec, and some cranberry juice. ENJOY!!

Splash a bit of Tripple Sec, toss in a lemon peal and you have a party cocktail! Served it to my Minnesota neighbors in my constant effort to bring some South to this Northland!
