Pinnacle Complex 500g
Complex is a slow to medium fermenter and can be used in all red grape varieties when a contribution to the aroma profile of the wine is required. This yeast produces a good mix of fruity and spicy aromas while still respecting the varietal character of the fruit. Complex is best suited for the Pinot Noir grape variety when a balance of aromas is desired.
- Complex has a medium lag phase with a slow to medium fermentation speed at temperatures of 20-29°C (68-84°F)
- Alcohol tolerance of this yeast is approximately 14.5% v/v.
- Complex is a low foaming yeast, hence can be used for barrel fermentation.
Complex is considered a medium nitrogen consumer, hence will need additional nitrogen following the initial addition at the start of fermentation to build yeast biomass (depending the initial YAN of the juice). It is recommended in low nutrient or highly clarified juices to add a complex nutrient when 1/3 of fermentation is complete to ensure a robust fermentation.
