Fruit fly eggs are yellow 1/2mm long and will generally hatch into larvae in ~30Hours, so if they are still there 2 days later then they are specks of stuff, if the hatch then they are larvae, which will likely fall into the liquid and drown. I hope that helps you. Edit: Oh, also CO2 tend to put the fruit flies to sleep, so if they were to fly into the ...
I would think that chemicals in your starting ingredients can affect fermentation if they contain preservatives. I imagine the right (or wrong, depending on how you look at it) kinds of preservatives will prevent fermentation (that's sort of their job, you know). Of course, since kombucha is usually just made with water, tea, sugar, and a starter culture ...
If the white bits are on the top, it is probably a mold. I once got this when I tried using honey as a sweetener instead of sugar. To get rid of the mold I first skimmed all of the white bits off the tea and then poured most of the brewed tea out except for a very very small amount. I then rinsed my scoby and added it to the small amount of brewed liquid and ...
If you are willing to drink a lot of beer and recycle the bottles, then Newcastle Brown Ale comes in clear cap-able bottles. Thats where my clear bottles come from. Enjoy!
You can always measure the specific gravity of any liquid with a hydrometer, but unless you know the starting gravity (as in, pre-fermentation), the reading won't actually tell you much. This on top of the fact that the byproducts of a mixed fermentation (alcohol, acetic or lactic acid, &c) will all have different densities makes a hydrometer reading ...
You can't ferment straight tea, because the yeast won't have anything to eat. You need to add some kind of fermentable (sugar, honey, etc) and some yeast. You're probably better off taking a recipe for something that's already fermentable (beer, wine, mead) and adding your tea to it for flavor.
