Static Fluid in Alcohol Bottle?

How would I have fluid that at the begging remains in the glass like real life alcohol not someone pouring it in?
How do I do that in Blender?

Most fluid tuts are fluid pouring it in to a mesh but I want my Fluid to for it to stay in the bottle in the beginning.

If you’re not animating, you could model/sculpt it. If you’re animating it, you could set the start frame (in the render properties) to a frame where the fluid is already resting.
