In High Isle you can get a quest called The Intoxicating Mix. When it is completed you get a container called Genalda's Clever Concoctions which has three drinks in it. The drinks themselves have the typo. I'd assume they are meant to have the name spelled as Genalda's but it actually is spelled as Grenalda's for each of the drinks. Grenalda's Ale, Grenalda's Punch, and Grenalda's Wine.
