Liquid Isinglass VINOFERM 100 ml

How do I know what fining agent to use?
One of the most convenient methods and still one of the best is trial and error: take a number of samples from the wine to be fined and put them in test-tubes. Add a few ml or grams of a different fining agent to each test-tube. Another test-tube of wine/juice with pectoenzyme and one with alpha-amylase (in starch-rich fruit) are helpful. Leave to clear for a few hours and you will see immediately which fining agent gives the best result!
