I know some say you cannot use some yeast from a bottle to culture that brewers yeast. I have read that you could with Chimay. I gave it a try and I did'nt see a drop in gravity, but I did have a fare amount of precipitant after a couple of days. Here is what I did.
I collected yeast from a Chimay Blue 750mL bottle. I shook the last 6oz and put it in a mason jar. Then placed it in the refrigerator. Three days later I made a starter wort of 1/2 cut to 500mL of water with the traditional 15 min boil. I also added 1/32 of a tsp. of White Labs WLN-1000 Yeast Nutrient. Placed it in my fermentation chamber at 68deg. on a stir plate. 24 hr later I stepped it up with 1000mL of wort 1/32 of a tsp of Yeast nutrient with the same 15 min boil regiment. 24 hrs later I checked it and noticed the high amount of precipitant on the bottom. I'm not sure if the precipitant was from the first 500mL or the 1000mL or both. Any thoughts on what may have gone wrong or did I not wait long enough to build up enough yeast to drop the gravity? Thank you for your responses in advance.
