Again, it will work in most standard gravity worts, but it is not optimal and most often results in under-pitching and introduction of excessive dead yeast into your new beer. If that doesn't bother you, then by all means, keep pitching dry.
you do know that yeast RAPIDLY multiply within a couple hours to 5-10 times what comes in the pouch and alot more than any "viable" yeast starter could ever put out, it would be far MORE better to air-e-ate to re-hy-drate and I seriously doubt and I dont care who or what the "experts" say that you would lose 50 percent of viable cells and not to mention there is "NO" I repeat "NO" difference in the quality and/or taste of the finished product.

Excellent. We will inform Dr. White of his errors, and pass your findings along to the Journal of Brewing Science.

Let's not. If you're interested in Chris White's career, you can find it. Enjoy.

Chris White wrote Yeast with Jamil Zainasheff. Considering the book covers every aspect about how yeast affects wort I'd imagine he knows some stuff. And in reality if Nottingham comes with 300 billion yeast cells losing 50% of that you'd still be pitching higher than you would with a smack pack that has under 100 billion cells. All numbers and facts aside, who cares. If you're method is working for you and you like the results then do it. At the end of the day all that matters is that you're happy with your beer.
