What IPA has the highest alcohol content?

I'm curious to know, among all the different types of India Pale Ales (IPAs) available, which one boasts the highest alcohol content? Is there a particular brewery or style that consistently produces IPAs with a higher ABV, or does it vary widely depending on the specific recipe and brewing process? I'm interested in exploring the world of strong, flavorful IPAs and would appreciate any insights you might have on this topic.
