2022 Chardonnay: day 7

 0500:

  • Brix 5
  • Juice temp 74 F, room temp 72 F, outdoors 55 F & cloudy
OK, still not quite 5 on the short scale, but closer.  
No visible bubbler activity, but I've made this sound recording of the sizzling inside the tank (after turning off the noisy exhaust fan).  Plenty of action.

Fiddling with the numbers while the juice burns: even though the brix numbers are getting small, the % of remaining sugar that's being converted daily is remaining large.  On day 6, when the brix budged from the prior evening's 7.5 to that evening's 5.25, 32.5% of the available sugar was converted, making it the third most productive day of fermentation.  (Why, really Why, do I feel like I need to say these things.)  

17:30
  • Brix 4.2 (short scale hydrometer)
  • Juice temp 74 F, room temp 72 F, outside 62 F and cloudy
OK, we're really under 5 brix, per the short scale hydrometer.  Juice looks and sounds much the same as this morning.  141 hours in since pitching yeast and about 84% of the sugar has been converted.  The current ABV is theoretically as high as 12.2%, with plenty more to go.  We'll see where we are tomorrow morning, but it feels a little less likely today that we'll be racking on day 9 than it felt a couple of days ago.
