In 1998 Marcarini introduced a change in vinification. They changed the pumping-over system, "rimontaggio", and introduced an automatic system that drips the must over the skins very gently so the extraction comes through the constant flow of the juice over the skins. In the past, the pumping-over was done by hand and the skins were submerged during the process two or three times a day. In the old system, there was a much harder friction between skins and the juice. With the new system, the pumping-over is done very slowly 24 hours a day. At the end of the fermentation in 1998, they compared the analysis of the wines obtained with the two systems and the result was that the quantity of polyphenols and tannins was almost the same. But in the mouth the taste and the texture were different. The 1998 Marcarini Barolos were a blend of the new and old systems. "With this new system we get sweeter tannins that are more gentle. In other words, we obtained a more elegant wine, without losing the terroir that we consider very important"                                                                                               (Manuel Marchetti)                                                                         Utdrag av artikel på siten eGullet.org
