Bitter or sweet orange peel in a Gose?

Ingredients
1

I am very unfamiliar with this style.  I think I have only had it once.  But my wife loves it so I am planning to brew a traditional Gose but with orange peel.  I’m thinking along the lines of a sour Shock Top (which she also loves).

My question is which style of orange peel would go best, Bitter or sweet?  I’m thinking sweet, but…

2

Fresh orange peel I think would be better.  Just make sure there isn’t any piff

3

I’d go with the sweet too.

4

I have been thinking of using a tad of essential oil of orange, food grade.  Has anyone tried that approach?  It is an oil that may play havoc with head retention but peel has a lot of oil also. Thoughts, please.

5

I’d skip the orange peel and just use coriander.

6

Coriander is already in the recipe.  I am curious why you say to skip the orange peel.

7

Zest of 1 orange or 1 tangerine, but not both, would be great.  Tangerine zest is very powerful. It may take a week or more for the oils to dissolve in a sour.
