Yuki
I compared No. 6 and No. 7 that I bought and laid down in the winter. The specs are the same except for the yeast. To be honest, I can hardly tell the difference, but the No. 6 has a sourness that comes first and is covered by a mild sweetness, while the No. 7 has a good balance of sourness and fruitiness, and a good sharpness. Personally, I prefer No. 7.
