This file describes the contents of the WINE dataset |
developed for the CPE 365, Introduction to Databases, |
course at Cal Poly. |
The dataset contains information about the ratings of a variety of |
wines produced in California. The ratings were published |
in a number of issues of the Wine Spectator magazine. Version 1.0 |
of the dataset includes only the wines produced out of a single grape |
and only the wines produced in the state of California. |
General Conventions. |
1. All files in the dataset are CSV (comma-separated values) files. |
2. First line of each file provides the names of |
columns. Second line may be empty, or may contain |
the first row of the data. |
3. All string values are enclosed in single quotes (') |
The dataset consists of the following files: |
- appelations.csv : list of appelations/American Viticultural Areas (AVAs) |
- grapes.csv : list of grape varieties |
- wine.csv : list of wines and their ratings |
Individual files have the following formats. |
************************************************************************** |
appelations.csv |
No : line number in the CSV file |
Appelation: name of the appelation/AVA/grape-growing region |
County: county (if applicable) in which the area is located |
State: state in which the area is located |
Area: general geographic area in which the grape-growing region is located |
isAVA: a flag specifying whether the region is recognized as an American |
Viticultural Area (AVA) by federal regulations. |
Notes: "Appelation" is a general term for geographic grape origins in a wine. |
Grape origins are always listed on wine labels. |
In the US, appropriate origins are either AVAs (American Viticultural Areas) |
or counties, in which the grapes were grown. Most AVAs respect geographical |
boundaries (state, county, so on), but some - do not. |
In the dataset, some AVAs shown as located in a single county are actually |
located in multiple counties (we chose the "main" county of location). |
This is done to simplify the dataset. Other AVAs transcend county borders |
in ways that make county attribution meaningless. The value 'N/a' is used |
in such cases. General geographic areas, as they are currently used |
are subregions of a single state. |
************************************************************************** |
grapes.csv |
ID: unique identifier of a grape (line number in the CSV file) |
Grape: name of the grape varietal |
Color: color of the grape (a.k.a, color of the wine when made solely of |
this grape) |
************************************************************************** |
wine.csv |
No.: unique identifier of the wine (line number in the CSV file) |
Grape: grape varietal from which the wine is made (see grapes.Grape) |
Winery: maker of the wine (usually a winery name) |
Appelation: origin of the grapes (see applations.Appelation) |
State: state of the grapes' origin (same as appelations.State) |
Name: name of the wine |
Year: year of the wine vintage |
Price: price of one bottle of wine in (whole) US dollars |
Score: Wine Spectator magazine rating of the wine on the 100 point scale |
Cases: number of cases of the wine produced by its maker |
Drink: drinking advice |
Notes: only wines produced from a single grape are included in the dataset (no blends). |
All wines in the dataset are from California. Drinking advice is simplified. Either |
the field contains the value 'now' which means that wine can be enjoyed to its fullest |
potential at the moment it was rated by the Wine Spectator magazine, or |
it contains a year in which the wine is predicted to reach its full potential. |
Wine name is either a special name given to the wine by its makers and found on |
the label, or is the name of the grape varietal. |
