Science has answered many questions that were previously unknown concerning black truffle farms until just a few short years ago. Science has taken this once dodgy venture and has turned it into a very lucrative way of farming. The advancements in DNA testing has been a contributing factor in many aspects to this success. Some nurseries will even use DNA testing to make sure that they are only using Tuber Melanosporum ( the black truffle ) for their tree inoculation. This at times can be the only way to distinguish between similar types of truffles. But, we cant give all the credit to the scientists, as successful black truffle farmers deserve their due credit in helping to uncover many of the mysteries of the elusive black truffle. Basically, the collaboration between black truffle farmers and science are the main reason for such positive advancements in the last 15 years or so.
Make sure your black truffle trees are purchased only from a nursery that specializes in inoculated trees. Preferably from a local nursery that has been there for years and will be there for years to come. Trees are 6 Euros each in
