Remember to use the scoring scheme in the following table:

0 No cask ale available.
1 Poor. Beer that is anything from barely drinkable to drinkable with considerable resentment.
2 Average. Competently kept, drinkable pint but doesn't inspire in any way, not worth moving to another pub but you drink the beer without really noticing.
3 Good. Good beer in good form. You may cancel plans to move to the next pub. You want to stay for another pint and may seek out the beer again.
4 Very Good. Excellent beer in excellent condition.
5 Perfect. Probably the best you are ever likely to find. A seasoned drinker will award this score very rarely.
