I am interested in this idea that one of the strains could be a weizen yeast. The beer is definitely cloudy and the label states that it is fermented with a special blend of strains.
I plan to get to the bottom of this. I took some bottle sediment a couple of days ago and it is growing quite slowly. No surprise, since it came from a high grav. beer.
My searches have turned up some conflicting information on this beer.
Here is a list in which someone claims to have had success in culturing the yeast from a bottle:http://www.nada.kth.se/~alun/Beer/Bottle-Yeasts/
Here someone gives a little more detail, but clearly did a bulk harvest in liquid, never separating to single colonies. http://www.homebrewtalk.com/f12/la-fin-du-monde-yeast-harvest-119973/
The thread goes off the rails and doesn't have a resolution.
Here we have someone claiming that this ale is bottled with a different strain than was used for fermentation: http://www.homebrewtalk.com/f14/la-fin-du-monde-12244/
I am not inclined to believe this last claim but I would be happy to hear anyone chime in with more information.
Since different strains have different flocculation characteristics, my yeast harvest is not likely to consist of the same strain ratio as was used to pitch. Therefore it seems like it would be best to separate the strains and pitch separate starters.
In order to determine if there are different strains in that bottle I am going to streak my harvest to single colonies and make many small starters with individual colonies. My hope is to find different flavor profiles in the starters that can help me to identify the different strains and separate them. I know there are probably better ways of doing this, and I am open to suggestions.
...and waiting for Wyeast 3864 to come out again is just not as fun.
