Olive Garden is not a place I frequently visit, but after tasting their iced tea that may change. During my last visit, I asked the server if he knew the brand of iced tea they serve. His response was, “I can’t tell. It comes in bulk and the only thing the box says is iced tea.” I had a suspicion based on the taste and that description that it was S&D brand iced tea. This suspicion was later confirmed when I contacted their customer service by email. S&D iced tea is also served at one of my top choices for fast food iced tea, Chipotle.
While S&D is mainly packaged for commercial use, you can order it both from Amazon.com and from the S&D website. This tea also made my top choice for home brewed tea. You can read about my preferred way to brew it here.
