Here is a single page that has the rules for potions, and 20 standard potions with flavors and qualities for a certain region/culture.
Imagine that you could edit each of the numbers on this list from d20 to percentile so you could weight entries to your liking. Imagine leaving all these potions the same and changing their qualities to that of potions of goblin manufacture.
Anyway, I couldn't achieve that, so I'll give you the Write file that you can edit if you want.
I had a heck of a time fitting the info. The side effects probably need some description, the potion mixing chart doesn't gives specifics, etc. I even cheated a little by allowing for fire/cold/acid resistances to be listed under one potion. I did the same for elemental form, figuring Elasticity could fit under it too.
But I really wanted a single page so I can find it in the heat of play. I put the bottle pic because I noticed that the more charts I have the harder it is to find something because they all look the same. So a simple image to signal what each chart is about.
Update: Trying to minimize more, I was able to cut the whole Color column by making the Quality backgrounds the potion color. But it might look better if you just printed in B&W and then use markers or crayons to color. I'm going to do this for myself because seeing red is faster than reading red.
John made the great suggestion that there should be a place for the hints of clues players will get when they sip the potions. I'm having a hard time fitting it, even after cutting the Color column, but if you care less about the Qualities/Flavors see the comments below for an example of How he did it.
