I found my new favorite alcohol, but can someone explain this to me if you can?

I recently found the best vodka ever, well to me anyways, I’m sure most of you have heard of it.

It’s called Stolichnaya and it’s so smooth, my favorite is the salted caramel.

But what’s the difference between Stolichnaya and Stoli Vodka?

As they were right beside each other in the same bottles and font, but just the names were different.
