New Year´s Eve is coming soon and as I am currently doing some Data Science courses at edx, I thougth analyzing the Champagne brands could be some fun.
Where do the data come from? I collected the prices & other information for several Champagne brands on the website „Gourmondo.de“ as it has a variety of products & bottle sizes. Accordingly I collected bottle size, brand, price per bottle, Normal vs. Rose-Champagne & whether it is a Special Year Edition (incl. Vintage).
I analyzed the data with R Studio and made some plots with ggplot. Let´s see what is in the data:

Rose is in average slightly more expensive than products which are not rose.
Products with a Year label are about 3 times more expensive than unlabeled Champagnes.
So if you want to buy some special Champagne for New Year´s Eve, you should choose Rose and not concentrate on Vintage. The most expensive price is, that is quite obvious, is Rose Champagner which is labeled with a special year.
Not labeled & not rose: 94,47€/litre
Labeled & not rose: 275,67€/litre
Not labeled & rose: 104,72€/litre
Labeled & rose: 310,63€/litre
Please be aware, that these data only show averages and do not represent all Champagne brands. Nevertheless, I hope these results were interesting for you.
Happy New Year!!!
