MAKING YOUR LATE HARVEST WINES When the growing season is hot and dry, the vineyardist is more at liberty (less at risk) to manage the vines and the fruit for the possible production of a true late harvest. A few late rains in September and early October will be all that is needed to encourage the "Noble Rot" Botrytis Cinerea to form. This unique fungus dehydrates the berries causing actual raisins to form on the cluster. This dehydration concentrates the sugars, aromas and flavors of the grape. Delicious hints of apricot, peach, raisins and honey permeate the juice and the wine to be. A few things to keep in mind when crafting your "Late Harvest":
With your Late Harvest Vignoles (Ravat 51) we are recommending an adjustment of the total acidity (TA) up to a figure of 1.1% if necessary and stopping the fermentation at a level of 6o Brix (hydrometer reading). To adjust your total acidity from say .855 to 1.1 – use tartaric acid at a rate of 40 grams per 5 gallons (OR) acid bend at the rate of 35 grams per 5 gallons. An application of Bentonite at label recommended rates might assist in the clarification of the wine. To arrest the fermentation use a combination of racking, the addition of metabisulfite and sorbate, and chilling when the desired Brix level is achieved. If you chose to make your Riesling as a Late Harvest, it is optional to use Cotes Des Blanc (Epernay2) for the fermentation. We recommend a total acidity (TA) of .9 to .95 with an initial Brix of 23 - 24 degrees and stopping the fermentation at a level of 2o Brix (hydrometer reading). Proceed as above for the clarification and stopping of the fermentation. Good luck and enjoy. Basic info: 1.9 grams (1/4 teaspoon) of tartaric acid per gallon will raise the acid approximately .05%. The recommendation of less acid blend is based on the use of citric acid in these blends.
Citric acid will not be reduced by cold stabilization in case of overdose. Pick up a tartaric additive sheet. Year 2003: The acid on the "regular Vignoles is 1.35, leave it there and bump the sugar brix to 30 degrees by addition of corn sugar or by freezing the juice to concentrate. One of our favorite customers has a procedure for freeze concentration in the fall issue of the American Wine Society journal. http://www.AmericanWineSociety.com for contact information. |
