Ratings are based on Sweetness, Acidity, Fragrance, Balance, etc. The rating is indocated by the total_cup_points variable where the scale is from 0 - 100. It also contains information about the processing method, expiration date, number of bags, bag weight, country of origin, company name and farm name.
The data set contains 1339 rows and 43 variables.

All through our lives, there definitely has been a coffee lover we know or we will be coffee lovers ourselves. Coffee has helped a lot of us to stay awake to complete our assignments or any other important tasks. It has also worked adversely for many of us, where we drink coffee at very late hours and find it difficult to fall asleep. Coffee was first exported from Ethiopia to Yemen in the late 15th Century. This analysis will help in understanding the nature of the different coffee beans (Arabica and Robusta), the regions where it is grown, the ratings for the different types of coffee beans and also the processing methods.
