FYI - the annual 'Feira do Porco Alentejano' in Ourique, Portugal has grown considerably in size over the last few years and now attracts producers form all over Portugal as well as Spain. Some amazing products made by artisan producers from traditionally reared black pigs. The 2017 dates don't appear to be published yet, but is likely to be mid March.
Will try and upload some photos over the next few days, but in the meantime a link to the municipality's page/videoclip.
