Tsubaki Sozen's "Black Tea for Bread (Asatsubaki)" really goes well with bread! The aroma is gorgeous, and it has no peculiarities, making it a delicious cup that you can drink in gulps.
I actually bought and drank the "black tea for bread (Asatsubaki)" sold at the tea specialty store Tsubaki Sozen, a cup of black tea created to go with bread every morning, aiming for a taste that you won't get tired of even if you drink it for 100 years.
