Hi!
In the last few years, I've started culturing all of the liquid yeasts I purchase (my local HBS stores don't carry liquid cultures, so I rarely get a new one). I only have pure strain yeast cultures at this point (a handful of ale slants and a lager slant).
I was wondering if it is possible to culture a lambic blend yeast (Wyeast 3278, for example)?
If so, do I culture it the same way as pure strain non-lambic yeasts? Streak on a plate, incubate, streak on a slant, incubate, store...
Do I need to do anything special in order to maintain the non-yeast portions of the blend?
I would imagine that the different ingredients in the blend would grow in different areas of the streak, so inoculation would require a scrape from each section of growth, but I'm not sure.
If I make a, say, 1L starter with the original, commercial culture, will saving 100-150 ml of the starter provide an equivalent culture or will this diminish the non-yeast portion of the blend?
Thanks!
