I have some kombucha scoby that I let go way too long (had to leave town for a bit, new job…) and it has gone to vinegar. I would hate to just throw it out as it’s delicious vinegar. I’d like to give out small jars to friends and family. Can I use any regular bottle or even after this long will it keep producing co2? If it’s still pumping gas it needs to be bottled in bottles that can handle it. How can I know if a bottle is safe for bubbly liquids? 
I would suggest, for the combination of "possible pressure" and also "easy dispensing and resealing" flip-top bottles (ceramic stopper and rubber washer on a wire bail arrangement) which were (or are intended if you are not re-using) used for a carbonated beverage (examples common in my area are Grolsch beer in green, or sparking lemonade in clear bottles. Brown beer bottles are also seen occasionally.) I do, in point of fact, use one of these for balsamic vinegar (but that's not actively fermenting, from what I see.)
