Hi Sara, I bottled my gallon just over two weeks ago and my wife and I cracked open a bottle last week and we thought it was very drinkable. I did not have anything very much to compare it with except that the owner of my local wine and beer making supply store, coincidentally, had acquired a bottle of commercially produced tej and he offered me a sample to taste about a month ago. (He and I share samples from time to time and offer each other feedback). My tej was more dry than the commercial brand and was not as clear.
One of the students (they are all adult learners) at my college is from Ethiopia and he is familiar with tej. He offered to taste my tej and give me some feedback. I gave him a bottle and he has offered to send me a couple of glasses traditionally used to drink tej. For the record, he is not one of my students so there is no conflict of interest here.
