Interpreting The Data

Figure 1 – Summary of Statistics for various wines

There are many variables for the 1,599 different types of wine including but not limited

to fixed acidity, citric acid, sugars, chlorides, sulfur dioxides, density, pH, alcohol content, and

quality. Residual Sugar (RS) is from natural grape sugars leftover in a wine after the alcoholic

fermentation finishes and is measured in grams per liter. RS levels very in different types of wine

with “dry” containing about 10 g/L and sweet wines have around 35 grams per liter. Our sample

has a mean of 2.4 g/L with a maximum level of 15.5 g/L and a minimum of 0.9 g/L (Wine Folly,

2019). Sulphates are naturally occurring compounds found in all wines; they act as a preservative

by inhibiting microbial growth. Out of this sample the maximum sulphate is 2.00 and has a

minimum of .33. White wines tend to have higher levels of sulphates dioxide added to white

wines as they are more susceptible to oxidation, whereas the tannins in red wines act as a natural

preservative (Preserving the truth on sulphates in wine - Wine Selectors, n.d.). The alcohol

content of mean is 10.42 and the minimum alcohol content is 8.4 and the highest content is 14.9.
