Ok. Just added 30g of potassium carbonate. The guy at the homebrew supply shop confirmed this was the stuff. I will take a pH reading tonight.
Thank you all so much for being so helpful!
No worries, let us know how it reads after your wait......

Took some readings tonight and I am very surprised.
S.G.: 1.030
pH: 3.62
T.A.: 4-5 g/L
I was expecting a movement in pH of 0.200 and I got a movement of 0.700. Should I be shocked? What am I missing here?
I think I am decently happy, though now I am wondering if the pH value is too high? I normally see people shooting for 3.300 or so.
That seems extreme for a half dose, did you completely degas your sample before testing the pH?
No. Did not know that sample needed to be degassed. Can that make a significant difference? Will try again tonight.
Specific gravity tonight 1.030... still. Vacuum degassed a sample and re-checked pH... now reading 3.60 so a tiny change at most.
Starting to worry about stuck fermentation now. I bought another 5g yeast packet... is there anything I can do with that to get it going again?
I am also starting to wonder if I should press and transfer to a secondary carboy... its been 8 days since adding the yeast now.
Thoughts?
What yeast are you using?
You've got the pH up, and assume you are now maintaining temps around 75, and you've already dosed twice with nutrients, correct?
What nutrient did you use and what was the dosage?
Personally, I wouldn't press until AF was nearly over.
Hydrometer reading 1.018 ... getting close!
Exciting update. I pressed and transferred this morning. Specific gravity was about 1.004 or so. I ended up getting about 6.5 gallons. You can see my 6 gallon carboy is not quite full and I have a little over half a gallon in a one gallon carboy that I will be using for top up when I transfer off the gross lees in a few days.
Please we critique my next steps because honestly I am not sure.
1. Let the carboys bubble for 4 days or so to finish off fermentation.
2. Rack off gross lees and add 1/4 tsp kmeta and oak chips
3. Wait a week and transfer leaving oak behind.
4. Wait 3 months, add 1/4tsp kmeta and bottle
Sound about right?
My steps woul be:
1. Let the fermentation continue until you have no drop in SG for three consecutive days.
2. As fermentation slows, gross lees will drop, rack off of them in 2-3 days whether fermentation is complete or not, they can get stinky.
3. When fermentation is complete, add KMS and oak if you want oak, leave it in until you think it's a little stronger than you want it to be, it'll fall back in aging.
4. Rack (if needed) and KMS every three months til you're clear as a bell.
5. Sweeten / sorbate if desired.
6. Bottle a week later.
Excellent. Thank you. DO I keep it at fermentation temps (70-75) during the whole process? OR do I lower it to 60's after fermentation is complete?
I racked off the gross lees this morning and combined the 1 gallon and 6 gallon batches for about 6 total gallons. I got a little frusterated because as soon as I started racking, some of the sediment from the bottoms floated up and made it hard to not transfer the sediment. It seems like blueberry lees are 'ligher' or 'less dense' than what I am used to with wine made from grapes? Needless to say, I found a bunch of sediment in the bottom of my carboy even after racking, so either I screwed up, or maybe this is normal?
Specific gravity is now down to 1.000 and it seems to be slowing. I'll rack again and add kmeta after 3 days of no S.G. movement... probably this coming weekend if I had to guess.
