Survey of the Thammasat University by randomly selecting students 10 people Female 4 and Male 6. Comparison of two tea brand is ichiton Green Tea and Oichi Green Tea. The conclusion that students like the green tea and 2 brands. But there is a part that like the green tea of ichitan that by the reasons that is not bitter and sweet not too. And the group that like oishi more than that the green tea that has a flavor intensity and are familiar with the name of the brand more than. This is to make a survey about a love of the students to the green tea. The 2 brands I hope that this survey will be useful to the others.
