  9. 9. Digging out my first tank<br />
  10. 10. Winery Practices<br />Tank cleaning<br />Current practice uses cold water and caustic soda followed by a sulphur/citric rinse, then a water rinse for tanks which have heavy tartrates present, or a multiclean wash for less dirty tanks. <br />Hot water needs to be available in the winery in order to make cleaning tanks easier. A hot caustic soda wash is more effective and takes less time than using cold water.<br />
  11. 11. Barrel labelling<br />Barrels are numbered and labelled on both ends.<br />Can be hard to locate barrels when they are stacked high and close together.<br />Barrels need to have the numbers and wine code sticker on the side on one of the rings.<br />Would make locating barrels easier when they are stacked high.<br />
  12. 12. Off site barrel storage<br />Barrels stored at Wine Warehousing as there is a lack of floor space at Matariki.<br />Managed well.<br />Can be a hassle when it comes to checking the sulphur levels once a month. <br />

  14. 14. Record Keeping<br />Ezywine is the record keeping system that Matariki uses.<br />Enables records to be kept in order to trace grapes back to their origin.<br />
