from hanging out on these forums and thanks to these guys here you'll learn quite a bit. My experience with taste change is that it can be cause by many different factors. I tend to be a bit impatient and smoke the cigar a bit faster than you should resulting in hot boxing which happens when that tobacco gets too hot and burns too quickly. (I think if I'm wrong one of the more experienced guys will let me know) You may also want to check your humidity % in the Humidor you want it to be anywhere from 65% - 70%. If your cigar gets too humid it will effect the burn and also the taste. You will also want to drink something while you smoke, your favorite beer, liquor, soda or water. Not something like OJ though cause they do not go well together.

Well that's my 2 cents. Welcome to the board and enjoy smoking.
