Trying to push Blender4.0 beta to see if I can create a realistic cocktail drink.
Thought I’d add a little more info to this render -
Cucumber slices and long cucumber strips are just the largest images I could find on the internet which I then converted into 3d objects and added the image as a material. For the strips of cucumber I used Blenders ShrinkWrap to deform these to the shape of the glass and then added Blenders Solidify to give some depth to the object. The mint leaves are created pretty mush the same way.
Ice Cubes started off as Blenders Default cube 
added a SubD and some slices and just pulled around the edges to make them look deformed. I then added Blenders Deform set to global so when you move the ice cubes around they all change shape slightly which helps to make them all look different.
Floor is a dark material with a low roughness to help give some soft reflections.
Back ground is a darkish material with a spotlight added to it to create the halo effect around the glass.
Lighting is pretty simple - two hard lights, main one is to the left and the other is on the right but behind the glass make a nice rim light.
