Example Input: This peach flavored diet tea by Snapple is extremely refreshing after a long summer's day! It's truly a diet tea--there are zero calories. It's best served chilled; and it has a mild but not overwhelming peach flavor to it that is just right. Snapple makes this with green and black tea leaves; there's also a mild green tea flavor mixed in with the peach flavoring. They use filtered water as well. This tea is sweetened somewhat with Aspartame; but Snapple adds in just the right amount so that it's not excessively sweet. If you want really tea that is rather sweet, you'll either have to look further or use this with added sweetener. It also contains phenylalanine and it is kosher if these are dietary concerns for you.  If you have other questions, the company has a toll free number so that people can contact them.  Overall, this tea is perfect for a hot summer's day when you want something cool to refresh yourself and whet your whistle. I highly recommend this product.
