BoochMakers
I don't think it's weird at all, I can't tell the difference in mine either! I always have to get others to try out my batches to tell me if they are sweet or vinegary or what ever they taste, otherwise I just don't know! So my advice is to just ask others to taste it, if anyone is brave enough to try it.
F1, F2, pellicle, SCOBY, the dictionary didn't know of these words.
Nope, you will still get carbonation, but it depends how much the bottles are leaking. I recently bought bottle caps for old kombucha bottles I have, their original caps were thrown away so I ordered what I thought were good ones. I filled almost 30 of them up and found out they were also leaking like yours, but they still carbonated really well.
If anything, it prevented the overly excess fizz that would turn my bottles into a nuke, my kitchen is much cleaner now.
Rose petals and pomegranate are my top choices, they work well every time and are not too sweet. I don't even have to add any sugar to it to get carbonation either.
