It’s now been about a week since I plated the DCambic sample. A few days ago I began to see growth of what appear to be yeast colonies growing on the malt extract plate. They are round with small peaks in the middle, and appear to be a little glossy. It’s hard to tell right now because I am not opening the plates just yet to avoid contamination. I want to leave these out for at least three weeks to allow any slow-growing organisms to appear.
There is also some yeast growth in the liquid sample. I began to see a layer of sediment a few days ago. No pellicle or visible signs of fermentation, but the pH dropped to the mid 4 range (using strips to check) and there was a somewhat Bretty aroma. There is a little funk but the dominant smell is sort of fruity, not unlike canned peaches. I am stepping that up to 250mL as we speak.
Once I’m done with incubating I will streak out the individual organisms and grow them in liquid. It’ll be interesting to see if I get the same characteristics as in the current liquid sample.
