Why are my pickles tasting spicy?

So I have had a non-spicy pickle taste really spicy before and it kind of got me into resurging and I found that vinegar is really sensitive for some people like some people can be very sensitive to vinegar and feel like it's spicy especially when it comes to pickles but some other foods as well that are covered in vinegar and it's because they're sensitive to the vinegar and the vinegar messes with your senses and causes a false pain sensation for some people and I have pickles that are blind and calcium chloride, dill, natural spices, water, salt, garlic, and mustard seed, it might be the spices but I doubt it that's pretty standard Brian for pickles except for calcium chloride is usually gonna be replaced with vinegar but I'm wondering if calcium chloride is similar to the vinegar and how it reacts to the palate for some people. I mean all honesty here is that even possible? I don't vinegar as a false spiciness for some people but I don't know anything about pickling with calcium chloride I thought these were interesting pickles so I got

 them but they are kind of spicy sort of. there really super good pickles but for some reason they are very much more like sauerkraut than your typical pickle flavor and they also have a spiciness today and maybe that's their calcium chloride . I'd appreciate any information that would be kind of neat to know.
