More of My Favorite Things

I found a new iced tea that I want to add to my favorite things list.  It is made by Rishi Tea and is called:

Organic Artisan Iced Tea

Classic Citrus

It's a bit expensive if you're used to buying the family sized Lipton or Louisanne family sized iced tea bags (it's $6.99 for 5 tea bags).  But it's a good treat.  The flavor of this black tea tastes naturally sweet and it very....herbal.  Sugar not even needed!  The box boasts that the citrus flavor actually comes from the essential oil of bergamot.  I wonder if I could make the Lipton taste like this if I bought some bergamot essential oil?
