VIN 7

Sauvignon Blanc, Sémillon, Chenin Blanc

S. cerevisiae • hybrid

  • Product of the yeast selection program of Infruitec-Nietvoorbij, the wine and vine institute of the Agricul­tural Research Council in Stellenbosch, South Africa. VIN 7 is a hybrid yeast isolated from nature.
  • Best used for cool, stainless steel tank fermenta­tions. Tends to ferment slower towards the end of fermentation.
  • A very high thiol releaser and converter and thus very suitable for the production of aromatic wines from thiol-containing grape varieties.
  • VIN 7 is a sensitive strain known to produce VA when stressed. Stressful conditions may include pH of 3.2 or lower, must turbidity under 80 NTU, low fermenta­tion temperatures immediately following inoculation (under 15°C/59°F), high initial Brix (above 24) and nutrient deficient must. If you have concerns about VA production from VIN 7, please consider Alchemy II.
  • YAN must always be checked and adjusted appropri­ately prior to fermentation. Do not use if initial YAN is 80 or less. A complete yeast nutrient containing vitamins and minerals (DAP alone is not sufficient) should always be added 1/3 of the way through fermentation.
