Taste help needed

Hello all. Trying to figure out what is going on with my beer. I have made the following recipe twice now and I am trying to figure out two things. One is it appears to be too hoppy. I made a batch back in May and it was beyond perfect to be honest. The next two are too hoppy tasting and it appears to have too much carbonation. I poured glass last night and the bubbles were racing off the bottom. It is all grain and I did follow to recipe and I used 3/4 dextrose for a 5 gallon batch. Any ideas are much appreciated. I did dry hop with Cascade and I used Wyeast American 1056.

what kind of water do you use?

Simple tap

That might be it. Tap water differs with the seasons. Your water might have a different sulfate level in may as it does is in Sept/Oct. Also, don’t forget that although you may use the same hops their AA change as well.

Could you explain about AA
