Embodiment Construction

[0016] 1. Grape sorting, destemming and crushing, canning, adding sulfur dioxide: remove the moldy and damaged berries in the grape raw materials, destemming and crushing machine for destemming and crushing, put the crushed grapes into the tank, and immediately add 60mg / L Sulfur dioxide prevents browning;

[0017] 2. Add pectinase and cold soak for 5 days at low temperature: add sulfur dioxide for half an hour, add 100mg / L pectinase to react for 4 hours, cool down at 5°C and cold soak for 5 days to obtain the product grape must;

[0018] 3. Return to temperature to inoculate yeast and ferment with skins: return the grape must to about 20°C, add 200mg / L yeast laffortE491, start fermentation, monitor the temperature and specific gravity every day, and control the fermentation temperature at 16-18°C (control the temperature to make the wine The aroma is more pleasant), observe the fermentation situation, when the carbon dioxide produced by the fermentation lifts the grape pomace ...

Abstract

The invention relates to a production method for muscat type sweet le vin blanc. The method using muscat grapes as materials and utilizing fermentation with skin is used for producing sweet le vin blanc. According to the adopted technical scheme, the method comprises the following steps of carrying out grape sorting, stalk removing and crushing, and adding sulfur dioxide; adding pectinase, and soaking the grapes for 5 days in a cold mode at low temperature; inoculating yeast after temperature returns, and carrying out fermentation with skin; terminating fermentation; storing the grapes in a sealed mode; carrying out stability tests, filtering and bottling.

Description

1. Technical field: [0001] The invention relates to a production method of rose-flavored sweet white wine. 2. Background technology: [0002] In recent years, China's wine production has increased steadily, from 960 million liters in 2009 to 1.381 billion liters in 2012 (National Bureau of Statistics, 2012). But mainly red wine, less white wine, and even fewer other wines. In order to enrich the types of wine, people began to plant different grape raw materials for the production of brandy, champagne, mercier, liqueur, sweet wine, ice wine, etc., which greatly enriched the types of wine. In addition to the typical Chardonnay (Chardonnay), Riesling (Riesling), Sauvignon Blanc (Sauvignon Blanc), Italian Riesling, etc., which have been vigorously developed in white grape varieties, some rose-flavored varieties have also been developed, such as Pass grape (Myckat), Angto rose (Muscatottonel), muscat (Muscadelle) and so on. [0003] Myckat is native to the eastern Mediterranea...
