Had a cup of this yesterday at my local Tealuxe. It was my first time trying genmaicha, so I don’t have a basis for comparison.
This presented as a nice, sort-of roasty flavor to a solid green tea base. The base was a little vegetal, but not too much (it was subtle enough to not be off-putting in the least) and was very smooth. The rice added a roasty note to the tea, creating almost a toasted or “cooked” flavor. It left a noticeable aftertaste of cooked green veggies. It was quite good overall.
