Congratulations for your the first tomato! Yep, taste is very far from those you buy from the grocery stores. Your tomato tasted what tomatoes naturally should taste but nowadays majority of tomatoes are grown in unnatural environments like in huge greenhouses, where they get a lot of different chemicals and fertilizers. They also have to be enough hard by their skin that they will survive all their long way to the stores and still look good. All this has took away their original taste.
My parents, both at their 80´s, say that my tomatoes taste like those they got when they were children - at the time before industrial-style vegetable production started.
I too have got the first tomatoes - this is grape tomato variety (it´s called as "100s&1000s"):
It makes "hundreds and thousands" tiny sweet tomatoes:
Very suitable for the pots and to the balcony gardens.
