in the 1970s, some tuscan producers came to believe that the legal rules governing the production of chianti were to restrictive. or these vinters wanted to make wine outside of the allowed chianti zone. they coined the term 'super tuscan' to distinguish their wines from the inexpensive, low-quality wines that were associated with the term vino da tavola, or "table wine," that they were forced to put on the label. today, most super tuscans use the legal apellation of IGT, which gives producers more flexibility. the wines tend to be more, big and rich. some super tuscans do contain sangiovese, either 100 percent or in blends. but others are made solely from merlot from a blend of cabernet and syrah, or from even more unusual blends, like petit verdot, cabernet sauvignon, syrah and merlot.
