Well, Genmaicha is very nice too.
I had some of this tea, and used to drink in winter, because I found it very heavy comparatively to sencha (maybe it is due to the cereals added with the leaves), but I found it very energetic and awakening ! (usually one small cup was enough to keep me awake when I needed too). The taste is very good, you can feel the cereals inside! Like my sencha from Kagoshima, I purchased bio one, even if I'm not a 100% bio consumer. I just noticed that bio teas flavours are ...

Concerning summer, I prefer drinking classic sencha or chinese jasmined green tea. I tried russian tea once or twice, it's good but I'm not fond of this kind of tastes. For me green tea still rules (nice with mint too!)
