Most of the lighting was created with these 3 lights -
Top - Round area light with a 45deg spread to give a ‘Grid’ feeling
Middle - Square area light with a 90deg spread to help with back lighting the mint leaves, ice cubes and top of glass.
Bottom - Small area light bounced back onto a white place which helps soften and spread the light back towards the glass and illuminates the ice cubes in the glass.
Thanks! I do add a little bit of sharpening around the centre of the image, but I try to get as much as I can using contrast which helps for a more dynamic image too.
