Il Buon Vino Wine Fermentation Kit

The Il Buon Vino Wine Fermentation Kit is designed for wine producers looking for a complete set of products to support the fermentation of red and white wines.

What does the wine fermentation kit contain?

1. Selected dry yeast for the fermentation of red and white grapes, designed to promote a rapid start to primary must fermentation;
2. Fermentation activator for the fermentation of white and red grapes;
3. Sulfiting agent used before fermentation;
4. Sulfotannic tablets used to help prevent haze formation and for the preventive or corrective treatment of casse, rope and “giro” faults.

The sulfotannic tablets are also intended for protecting wine stored in partially filled vessels and during summer storage or transport.

Use and dosage

1. Sulfiting agent

Use 15–25 g per quintal for red wines and 15–20 g per quintal for white wines. Add the product to the grapes during crushing or immediately afterwards, always before fermentation. Subsequent punchdowns and/or pump-overs are required.

2. Selected dry yeast

Rehydrate the dry yeast in 10 times its weight of warm, sugared water. For each litre of water, use 100 g of yeast and 50 g of sugar at a temperature of 35–40 °C.

Stir thoroughly and leave to stand for 10 minutes. Stir again, wait another 10 minutes and then add to the must to be fermented.

Warning: do not rehydrate the yeast directly in the must or in cold water. Do not leave the yeast in the rehydration medium for more than 30 minutes. To avoid thermal shock, the temperature difference between the rehydrated yeast and the fermentation tank must not exceed 7–8 °C. If the difference is greater, cool the yeast gradually at intervals of 15–20 minutes.

3. Fermentation activator

Immediately after adding the yeast, dissolve the fermentation activator thoroughly in a sufficient quantity of water, must or wine and add it directly to the batch.

Carry out punchdowns or pump-overs twice a day.

4. Sulfotannic tablets

The sulfotannic product is supplied in a tube containing 5 tablets of 10 g each and should be added after racking.

• Finished red wines: 1 tablet/hL;
• Unfiltered red wines and white wines: 2 tablets/hL;
• Preventive treatment: 1 tablet/hL;
• Corrective treatment: 2 tablets/hL.
