In 2010,
we used a commercial puree provided by the Hudisa Company (Huelva).
Sulphur dioxide (60 mg/L),
sucrose and two types of pectolytic enzymes (Depectil extra-garde FCE and
Depectil clarification from Martin Vialatte Oenologie,
Epernay,
France),
both at a concentration of 15 mg/L,
were added to the puree.
After this point, the procedures were slightly different in each harvest.
