Many brewers filter out their proprietary yeast and use a neutral yeast for bottle conditioning so you may not be getting the yeast you want from the bottle. I used to have a list of beers that were bottled with the fermenting yeasts but it was so out of date it's useless now.
I'd say it's more like "a few" than "many" that filter out the fermentation strain.
I bottled this beer today. Absolutely no doubt that this is the fermentation strain. The taste and aroma is spot on and this beer gets a lot of its flavor from the yeast. Btw this is the first beer that I have brewed with advice from this forum and it was a great experience. I really appreciate peoples advice and generosity.
