So just a quick update. It's only been what 3 days maybe? And the 3 starters I have out at room temps are tasting similar to me. That's one CY leaven, 1 patsy's, and 1 ischia.
Now this is a premature update, but still worth noting. I tasted the starters at the 23rd hour prior to feeding so they are well ripened, not over ripended but well ripened. I just refed, and will retaste in the morning (8 hours after feeding) just to see where they are at.
The CY leaven so far has taken on a bit of a sour note. Not nearly as much as the other starters, but still more than what was originally there. Originally it had no flavor and a slighty sweet aroma, almost like apples. I can not detect the sweet aroma and it has a very light acidic taste. To smell and taste it doesn't remind me of apples at all, which I would describe the original leaven as.
I took out the CY leaven I have in the fridge which hasn't been feed for the last 3 days. When I open the jar, it smells distinctly like sweet CY. I taste it and it is also slightly acidic but different from the room temp one. Less acid and just slightly sweeter. I don't know if the sweetness is there or if my brain is just picking up the scent of it and telling my tastebuds it's slightly sweet. Either way, it's different from the room temp one.
The patsy's starter has definitely lost it's sweetness in taste. I open the patsy's starter from the fridge and taste it and it has it's unique sweet taste that I like. The room temp one at this 23rd hour, has lost that and a bit more acidic than the fridge one.
The ischia, I couldn't test against the cold one, b/c I had pulled it out earlier and fed it with WW to make bread. I'll test it another day.
But at this point, the flavor of all 3 room temp ones taste somewhat similar in flavor to me, not distinctly different as I am use to. The acidity of the patsys and the ischia is similar to eachother, while the CY leaven at room temps is distinctly less acidic but has a similar flavor profile.
UPDATE: 430am (6 hours after last feeding). All 3 are puffy, so active but no where near peak. I tasted all 3 and all are semi sweet tasting. The Patsy starter I'm not surprise but the ischia I've never really would have describe as sweet. The CY leaven has just the tiniest acidic bite over the others which seems uncharacteristic.
The true test will be to refeed these as a 100% hydration starters and allow them to become active and then compare that to the active starters from the fridge. I'll do that test next week sometime.
