Super Yeast

[monk]

Hi everybody. Just wondering if anyone has much experience with Munton and Fison Active brewing yeast, the dry type. I used it for the first time on a blonde ale I brewed Saturday and it was super fast. The wort was ~1.037 og, and I used two satchets of M&F rehydrated in warm water. The krausen had mostly fallen by Sunday night and it's already beginning to clear. I fermented at about 20-21C, but started a bit higher, around 27C. Do you think it just worked fast, or did I start fermentation at too high a temp?
