===Dry Hopping===
(in progress)
Brewers have had positive and interesting results dry hopping sour and funky beer. Often fresh American or New Zealand varieties that compliment fruit flavors are chosen, however other varieties have been used as well, including English and German hops. Just as in dry hopping normal beers, dry hopping sour/funky should be done after the beer has matured. Dry hopping for around 1-3 days is adequate for extraction, depending on whether or not the beer is recirculated or agitated (agitation of the beer while on contact with the dry hops attains full extraction in 24 hours) <ref>[http://ir.library.oregonstate.edu/xmlui/bitstream/handle/1957/34093/Wolfe_thesis.pdf?sequence=1 A Study of Factors Affecting the Extraction of Flavor When Dry Hopping Beer (master thesis).
