At day 5, I sanitized and cut up 3 lbs. of fresh apricots. I kept all of the pits. Fresh peaches would have been ideal, but those don't exist in late December, so I used frozen slices from the store. I pureed all the fruit and added that with the pits that I kept.

At day 8, I used a dried out piece of oak and cut it into chunks. I sanitized it and let it dry for an hour in the oven, then added it to the fermentor.

At day 9, fermentation from the fruit had died down. I added the full packet for each of the Lacto and Brett (Wyeast brand).

At about week 4, I found a couple large, ripe peaches at the store, so I added those.

Each time I added anything to the fermentor, I am introducing oxygen, so I add a little bit of simple syrup to get get the yeast to refill the headspace with CO2.

I bottled everything just short of 6 weeks total time. The result was super oaky. Tried to filter out as much sediment as I could because there was a ton. Next time I do puree, I'll put it my grain bag to keep everything a little more contained. I mixed in a combo of corn sugar and sucrose before bottling to try to get the CO2 level around 3 volumes.

Opened a bottle after 1 week. Really oaky and a little tart. Really good looking head that dissipated after a minute. Carbonation seems to have gone well and now I'll just let it rest for a few months to let the bacteria do its thing.
