Beer expired last year and this year We have lots of Blonde beer which expired last year and some expired May this year.  

Is it still safe to drink?
Most likely - Yes, it is safe to drink it.

Your beer is almost guaranteed to be safe to drink for humans. No pathogens like alcoholic beverages. If you have bacteria in your beer, you will just have another style of beer (see Sour Beer). 

Your beer could taste bad, but 1 year over expiration date is usually nothing serious. A lot depends on the type of beer + alcohol percentage + earlier exposure to oxygen + present bacteria in the beer.

When I brew Blondes, wheat beer or beers with belgian yeast, I'd rather have them condition in the bottle for several months before I drink them. Maybe your beer has become even better and more conditioned.

Good luck tasting!
