I think I'd rather have the brussel sprout
juice.
Yeah I forgot you were a mile high bottler now, that adds a whole different dimension to things. I know if you take an "empty" (full of air) thin plastic water bottle that was capped at 5000' and take it to sea level, the gases inside will reduce in volume to maintain equality causing the bottle to collapse.
Not sure how that plays out when you're dealing with viscous liquids. But I do know that unless all of the components (plastic, liquid, and any dissolved gases involved) compensate at the same rate, there could possibly be issues.
Starting to wonder if that's why I see some vendors only using glass. That would kind of suck imo, I really prefer the plastic.
Edit: Another indication would be (at least for mine) is they only seem to leak in transit. Once I unrwap and clean them up I've had no further issues. It also only seems to be like a small set amount, it's not like I've lost a large percentage of any of them as if it were a continuous release.
