Blender 2.68 Cycles
I modeled the bottles and cobbled together material settings for the glass and liquid from Kent Trammell's tutorial on Rendering Glass and Other Refractive Materials in Cycles with a few modifications. I used an environment map for the reflections on the glass. I used the Add Curve: Ivy Generator Addon for the ivy. I used a plane as an emitter in front of the window as my light source. I tried various other light set ups to get brighter reflections on the tile but the caustics caused too many fireflies so I toned it down quite a bit. I did a little bit of compositing on the final render, adding some glare and blur to the reflected light. I added a Despeckle node and it seemed to help soften some areas that were still a little pixelated.
