Harvesting yeast

[bastump218]

I want to harvest some dregs from a jolly pumpkin beer to pitch into a Saison I brewed with Brett b. My question is how fresh should the bottle be and is there a cut off of how old the bottle should be to try it. I have three Jp bottles all bottled in 2011.

There's not really any guidelines for this....It's doubtful most harvesters look for born on dates on the bottles of other beers they're using.

Just make a starter, if it takes, it takes, if not, try again.

Agreed. Try and find out. I have heard that some people have better results if the beer was refrigerated at the store instead of out on the shelves.
