Both times I've pitched it from a starter it takes right off. I think my mild was pretty much done after about 36 hours. I've only tasted a gravity sample but it tasted great, much better than the extremely low OG would have led me to believe. When I pitched into the RIS it was bubbling the airlock within a couple of hours. I was an idiot and thought because I only had about 4.5 gallons in the 6 gallon better bottle that I didn't need a blow off tube. I even woke up at 3 am to check on it and even though there was a big krauzen, it wasn't near the top. Well, the next morning there was RIS all over the walls, floor and ceiling. The good news is that it smells great. The fruitiness this yeast gives off is very pleasing and my fermenting RIS smells like young's double chocolate stout times 10. I've actually decided to do a chocolate stout with this yeast now after smelling that.
