Start with a black primer. I used Scale 75 primer for this prop.
I painted the bottle with Boreal Green from Scale 75.
When it's dry, start stippling randomly to create the effect of moving liquid and bubbles. First with Irati Green, followed by Spring Green both from Scale 75.
If it's not green enough for your taste, you can reinforce the saturation with a thin glaze of Inktense Green from Scale 75 or any other transparent pigment such as Contrast paint from Games Workshop.
Edge highlight everything with a mix of Spring Green and White.
I painted the cork, basecoating it with Dark Sand from Vallejo, followed by stippling it randomly while wet with English Uniform from Vallejo, and White.
For the leather I used a base of Chocolate Brown from Vallejo, and mixed Orange Red with Sunny Skin Tone from Vallejo to randomly stipple and create texture.
After that I washed it down with Agrax Earthshade from Games Workshop.
I painted the golden pieces with Dwarven Gold from Scale 75, highlighted with a little bit of Speed Metal and washed it with Seraphim Sepia.
After everything is dry apply a generous coat of gloss varnish to the glass parts. I used Klarlack from Marabu, but any will do.
