I don't use a blowoff, so I am not sure. But, from what I have read and been told, the stuff from blowoff and what gathers around the edges produces some really significant off flavors. That being said, it leads me to believe those flavors would appear instantly...so if the sample tasted great, you are good. Who knows, even if it did take on some blow off, you must might have created the next big thing! Keep us posted!
