Is 2 year old micro brew beer safe to drink?

So i got gifted a mixed twelve pack today, and realized after drinking one, that some of the bottles were over 2 years old! while i don't feel sick, but I'm a little concerned. The mix includes a couple amber ales, a few pale ales, an apricot wheat beer, a blonde ale and a Kona island lager. On closer inspection i realized they all have some sediment (some more than others). None of these are that dark (ive read that really high alcohol beers can be aged), so I'm wondering should i just send them to a water grave, or should i partake?
