I use both the spring and summer matchas to make delicious lattes with my Breville Milk Cafe frother. My daily latte is made with the summer harvest. If I want a treat, i use the spring harvest. Taste is similar although the spring harvest is a bit smoother. Just on taste alone, I'm not sure one is better than the other. Where the spring harvest shines is on the amount of froth it makes. There is a lot and it lasts a long time. It's a pleasure to drink!
