  4. 4. Squeezing and must <ul><li>Done by mechanical histruments </li></ul><ul><li>The juice or must is sent to steel tanks useful for fermentation </li></ul>
  5. 5. Red vinification <ul><li>The fermentation occurs in the must with the skins for the extraction of the colorants (antociani) </li></ul><ul><li>Fermentation needs the addiction of yeasts </li></ul><ul><li>Red fermentation needs a temperature between 22 and 25°C </li></ul>
  6. 6. White vinification <ul><li>The fermentation occurs in the must without the skins because we want a colorless wine </li></ul><ul><li>White fermentation needs a low temperature (16-18°C) </li></ul>
  7. 7. Sparkling wines <ul><li>Sparkling wine is a wine with significant levels of carbon dioxide in it making it fizzy. Sugar is put in the wine for the re-fermentation that produces bubbles ( carbon dioxide or CO2) that may result from natural fermentation. </li></ul><ul><li>Champenois method : re-fermentation in bottles </li></ul><ul><li>Charmat method : re-fermentation in large steel tanks </li></ul><ul><li>Both fermentation needs very low temperature (12-16°C) </li></ul>
  8. 8. Yeast <ul><li>Yeasts are eukaryotic micro-organisms classified in the kingdom Fungi, with about 1,500 species currently described.

  9. 9. SO 2 (sulfur dioxide) <ul><li>It’s a chemical additive </li></ul><ul><li>Positive effects: </li></ul><ul><ul><ul><li>Useful as antibacterical substance </li></ul></ul></ul><ul><ul><ul><li>Makes better colour in wine </li></ul></ul></ul><ul><ul><ul><li>Makes wines smart </li></ul></ul></ul><ul><li>Negative effects: </li></ul><ul><ul><ul><li>Dangerous for man because it produces sulphite </li></ul></ul></ul>

  11. 11. DOC and DOCG Controlled Origin Denomination <ul><li>Denominazione di origine controllata (&quot;Controlled origin denomination&quot;) is an Italian quality assurance label for food products and especially wines.
