Guys thanks for all the feed back ive been out of the brewing circle for nearly two years as ive been working away from home and im working hard to refresh alot of the things that I learnt, but still have soooo much more to learn. Charst thanks for all the great feed back and no you dont sound like a downer, all constructive feed back is most welcome. I took a look at the link for the yeast cals and have save them to memory. Down the track I hope to get a better understanding of the dark arts of yeast, I get that for high SG brews i need a really healthy and well populated yeast but am in the dark as to work out how I know if I have a big enough yeast. I had started to harvest yeast when I was brewing alot but never really understood the principles behind yeast volumes. I would just take a yeast sample that I had harvested and regrow it a few times increasing its size each time and then pitch. Probably sounds a bit naive but it always seemed to work. I really want to harvest the yeast from this IPA so i will have to read up and remind myself how to harvest and wash yeast cake. And maybe the next time I use it I will have a better idea of how much or what population size I will need for the brew im putting on.
Thanks again guys.
It really great to read all your thoughts.
