No not exactly... a) You can wash yeast only a few times (like 5) before you should scrap it, and b) Different strains of yeast for different styles, not to mention lager vs. ale yeast etc... lots of different strains out there to use!
You eventually will, but....
True, I mean if the vikings brewed beer just using the yeast left on their brew stick...I have jarred unwashed yeast for later use, as well as using 1/2 a yeast cake to just pitch the wort onto.
Both have produced great results.
The jarred unwashed yeast was refridgerated for 4 months or so.
Wyeast and Whitelabs have processes to be sure, but they aren't magic.
I am sure that the old german brewers kept the same yeast going for hundreds of years without stopping by the LHBS for a smack pack.
The technical answer would probably be yes, but the practical answer would be no. But you can "grow-up" the yeast from the bottom of your bottles. You start with small starters and pitch into larger ones to build up the colony. This is usually only done by brewers who want to harvest a yeast that they can't get at retail. You are much better off spending the $7 bucks buying new yeast and washing it next time, because you will spend way more than that on the DME needed to make the step up starters.I flushed my last yeast cake, and I now feel guilty while reading this thread. Would it be possible to wash the yeast from the bottom of my beer bottles?
Dude, you live in Indiana.Yep. Think of your carboy as West Virginia. There ain't nowhere else to go or nothin' else to do but inbreed. Over time, the inhabitants just get further from the current state of evolution.
