Very Smooth matcha, we blind tasted the premium and special edition together. 1tsp around 84-85 degrees. This one is noticeable smoother and has a very nice aroma. It can be drunk without any milk or additives. The special had a more bitter and tannic taste. I'd add some milk into the special version but this one is great without it.
Is it worth a $10 difference? It really depends, if you plan on not using any milk then definitely. If you like your matcha mixed with more milk then the special would work just as well.
