Wild yeast on frozen berries!?!?

[As-Ol-Joe]

I have been making strawberry panty dropper and a blackberry version of panty dropper.

I first soaked my berries on 60% for a few days then started putting sugar on the berries to get the juice out of them. After about a week, I had pulled all of the juice from the berries and didn't have enough juice to mix with the 60%. I went to the store, got some more berries and just put sugar on them. After the 2nd time of putting sugar on them I noticed that they were starting to foam and the fruit was totally turning to mush. Cracked open the jar lids and the pressure had built up so much that it kinda sprayed the kitchen table.

I am assuming that there is wild yeast on the berries when they are frozen and it wakes up when it get to room temperature.

I am also assuming that the 60% on the first batch killed the wild yeast.

Just thought I would mention this so maybe there won't be any jars blowing up.

You assumed correctly.The booze killed it on the first batch.I used to use the wild yeast on the fruit to start my wine fermenting.You just have to cut back on the sugar because those wild yeasts wont ferment as high.
Your lucky you caught it when you did.It could have been a glass bomb.
