My wife and i had a wedding and invited 300 people - who all showed up. We served Portuguese Vinho Verde (a little bit bubbly)and had many bottles left over. Casal Garcia is the vinyard and uses bottles with a lovely blue hue.

For my birthday, my wife bought me a glass bottle cutter. Now, whenever we need drinking glasses, i set up a table in front of our apt house and get the local kids to help me etch, heat/cool and sand the edges to make beautiful glasses - which they each get to take home at the end of the afternoon.

NYC produces many excess wine bottles everyday. Enough that we would probably never have to import new drinking glasses ever, if we use what we have.
