Fitzgerald’s novel does not specify the brand Gatsby’s revelers consumed copious amounts of, but the producer and director of DiCaprios film, with very good reasons, assumed it was Moët & Chandon. The company was an early pioneer in the export of champagne to lucrative overseas markets including the US and UK back when it was still largely a local secret; a French wine for domestic consumption. In doing this, the company was at the forefront of the now global reputation champagne has for excellence, one that allows it to enjoy an uncontested premium in price, perception and prestige over every other sparkling wine region on earth.
Its likely that the Orient Express, with its penchant for no-expense-spared quality would opt for champagne from Moët & Chandon.
Now, you can take the above image and size it however you want, or
Print this PDF, whatever works for you. Its best if you print it on matte paper.
Cut the label out, and using rubber cement, glue it onto your bottle.
I've found that its usually easiest to use water to soften the paper on the bottle and peel it off, then using steel wool or something similar, scrub any things left over off the bottle. Dry it well, then, put rubber cement on the new label, and place it on the bottle. use a few rubber bands to hold it in place until the rubber cement sets up.
Now, I hope that Moët & Chandon won't mind that I copied a label of theirs that I found on a google image search, and pasted it into a .pdf document so that I can print it out, and relabel a couple bottles of Martenellis sparkling cider as champagne, for effect.
