To me it sounds like the speaker says "Ba" not "Beh." Wouldnt that make it in the bottle rather than in a bottle?
oh my lack of english grammar...why is it incorrect to say "it is juice in the bottle". where to use there is vs vs it is?
"There is" is used in cases, where we want to say that something IS somewhere. I think you could say "it's juice" if you'd want somebody to confirm that it's really juice what's there. But even in this case I'd use the word "there" in another place: It's juice there in the bottle. I'm not a linguist - it's just my explanation...
