can you show the render with bubbles? Maybe, we can help you

(I already have an idea, what it could be...)

thank you for the nice appreciations

for Kram1032: the render with bubbles. It seems that the champagne is like a black hole... It absorb all the light... I've done another render with the champagne(in fact 2 champagne?!) outside the glass to confirm it.
If you have any clue about that (I've seen a similar problem I think on this forum about the blender' monkey but I didn't really undertood the solution...

) (so, sorry about the bubbles, they won't be visible until I have solved the problem.......)

Are your normals inverted perhaps?

Is your scale correct?

oh, lol, I didn't expect that

Yeah, what BbB said

Besides, before you do that mistake, also check your precedence

(glass should be highest, say 12, then bubbles with 11 and an air material of 1.0 IoR and 0 absorption and finally the champagne with precedence 10)

Hermetic volume for liquid ?

Hey but the second one is ok, it just has too much absorbtion I believe ! Let that coock more (omg thats coke in your glass

)

I don't think so, CTZn: It looks better, because the glass reflects.
The first one is the version without glass.
Else, they're similar.

Mmm yes ok

thanks for your help!

kram1032 is right, in fact the two pictures are inverted... the render with the champagne outside the glass to show that the reflects are due to the glass....

I've tried to switch the normal yet, I'll try again (maybe I was a little tired...).
I don't understand the meaning of this suggestion:

Is it about the object? the material?

It's about the object's size. You have to make sure your glasses have realistic size. If you have 10 000 litres of champagne, light is more absorbed than if you have 0.25 litres.

But it's such a perfect dark that I don't think it's a size issue.

Yes, looks more like normals to me. Having said that, scale in combination with absorption has a huge impact on the colour and transparency of liquid. You should make sure your glasses are roughly the size of real glasses.
