Ex Input:
So life with a gluten allergy can sometimes seem unfair; however, once bisquick started making this product, things got a lot more equal. It tastes like Bisquick. It works like Bisquick. Hey, it is Bisquick. It just happens to be gluten-free. Perfect pancakes! Enough said.

Ex Input:
Good quality nectar.  Very tasty.  However, I was expecting 46 fluid ounces, not 46 ounces in weight.  I find that 46 ounces in weight makes about 32 fluid ounces.

Ex Input:
Ingredients listed: Pure cane sugar, and 100% pure powdered Japanese green tea.  Nutrition Facts: all 0%, except Sodium (15mg) and Sugar (12g)  Basic Instructions: add one packet to 8oz of cold water and stir or shake well to dissolve...  My Opinion: It is too sweet for my taste, even diluted in a 16.9oz water bottle. It almost tastes like sugar water. I think the unsweetened version would be better. 5 star because it delivers what it promises.  This is Japanese green tea. NOT Chinese green tea. There is a difference.
