Okay, how much danger am I in? I used a Mr Beer kit...and bottling added priming sugar. Unfortunately I got on the wrong line - having 500ML bottles, I added the priming sugar for 1 liter bottles. 2 and 1/2 teaspoons and it called for only 1 teaspoon.

You could end up with bottle bombs, and even if you are lucky, when opening bottle with much more pressure, you risk gushing.

I would empty all bottles in a fermenter, leave it to ferment dry and bottle again with the right quantity of priming sugar. I prefer to prime the whole batch in a bottling bucket, then mix it well. When you prime the whole batch, you do not have to care about bottle sizes.

    Yes. If you don't do this, your bottles will likely explode.
