Hand picked Riesling is delivered to Petaluma for immediate processing. The bunches are de-stemmed, crushed and chilled to less than 5C then treated to Willmes tank presses. The free run juice is cold settled for a natural clarification then racked to fermentation tanks and inoculated. Fermentation is monitored over several weeks at temperatures of 10C to 13C rising to 17C over the last few grams of sugar. The wine is chilled to below 0C and the yeast allowed to settle. A gentle filtration retains all the fruit, dulcet aromas and lavish flavours.
