Liquid Gelatine
SIHA Gelatin Liquid fining agent from Eaton’s Begerow Product Line is a stable, 20% aqueous gelatin solution for treating grape mash and grape must.
Because it is easy to use, SIHA Gelatin Liquid fining agent is particularly recommended for the fining of mashes and musts and can usually be used without preliminary tests, based on empirical values. For the fining of wine and fruit juices, a preliminary test should be carried out to determine the individual requirements and optimize the fining effect.
Technical Specifications
SIHA Gelatin Liquid fining agent is a 20% solution. Five times the quantity of dry gelatin (cold-soluble gelatin) must therefore be used. It can be added directly to the product without any preliminary treatment.
Product Applications
Fining Preparation and Procedure
SIHA Gelatin Liquid fining agent is easy to measure and dose. Provided it is thoroughly mixed, it can be stirred directly into the beverage. For mash finings and in applications where mixers with inadequate effect and unfavorably shaped containers are used, such as rectangular tanks or concrete tanks, it should be pre-diluted with about 10 times the beverage quantity. For mash fining, the pre-diluted SIHA Gelatin Liquid fining agent can be added continuously to the mash flow. If small mash containers are used, the fining may be distributed directly on the grapes, possibly together with the required quantity of dissolved SIHA Potassium Pyrosulphite stabilizer. Mixing is then done during grape crushing, mash pumping, and filling of the press.
Before adding SIHA Gelatin Liquid fining agent to the beverage to be fined, it should be agitated with a high-performance mixer. Then, slowly add the gelatin solution to the beverage. In general, the gelatin fining will settle within one day. Flocculation can be improved and accelerated through secondary fining with BEVASIL 30 silica sol fining agent or SIHA Bentonite fining agents (all types).
Combination of Fining Agents
Particularly for clarification of must and young wines, we recommend combining SIHA Gelatin Liquid fining agent with negatively charged flocculation agents. The combination of SIHA Gelatin Liquid fining agent with BEVASIL 30 silica sol fining agent has been tried and tested. As a general guideline, a ratio of 1:5 to 1:10 (gelatin to silica sol) is recommended. The exact ratio should be determined in a laboratory test.
