Our trip to Spain was incredible!  We worked in the laboratory with the team at Micologia Forestal Aplicada for a day and then took a few days to tour several truffle orchards around Barcelona and Teurel. We visited with several truffle product kitchens and distributors and then feasted on over seven species of truffle in one meal! What a week of excitement!
