The Black Summer Truffle is the only truffle, which is available in fresh form during the summer. It is one of the most durable varieties and can last up to 2 weeks after gathering.
The Spring White Truffle is a perfect alternative of the authentic white truffle, when the white truffle is out of season. The good news are that the Bianchetto Truffle is cheaper and at the same time has very similar flavour, but more intense.
