Beer was an alcoholic beverage enjoyed by many people in Alagaësia. While in Dras-Leona, Brom and Eragon got drunk at an inn. Saphira rebuked her rider for this, but later got drunk herself at Farthen Dûr.
Beer was considered good for morale. When Roran objected to Morn and Tara joining the exodus from Carvahall with numerous caskets of beer because they didn't have enough food, Horst stated that the fact that the beer was good for morale was worth more than a few extra meals.
