To kick off 2011 in All About Beer (Vol. 32, Iss. 1) I looked at how beers today are conceived quite differently than when beer itself was still being created.

Authenticity versus innovation (or authenticity plus innovation) are factors allowing so deep a field of brewers to give birth to new beers.
