Sapporo is making a limited edition happoshu beer called Hopbatake no Kaori (ホップ畑の香り) or Aroma of a Hop Field. It is only being produced in 2012 and only in a limited volume. It advertises the use of "Furano Beauty" hops grown in Furano City, Hokkaido. It also advertises the use of a "fresh aroma production process" (フレッシュアロマ製法), but a quick search did not turn up any related patents.
