Why are my home-grown red bell peppers spicy?

Question

I decided to try my green thumb and this past spring after I bought a couple red bell peppers, I planted the seeds in 2 pots in a window of my apartment. Now I've harvested them and I tasted each of them and they are a little spicy. Not crazy spicy, but I was under the impression that bell peppers had no capsacin, or at least very little. Could this be due to me growing my plants from grocery pepper seeds? Maybe the bell pepper plants were unintentionally cross-pollinated in the field with a spicier neighboring pepper? The peppers are a bit on the small side. Any ideas? Thanks!

Answer 1

well it could be because the seeds that u used could have been over doced or maybe because there spoiled  and it could be because u took care of them a little to much
