Like SO2 , some lactic strains show resistance to lysozyme. Perform bench-top trials to determine the effectiveness and correct addition rate of lysozyme. I have a stuck red and the VA is creeping.
The wine isn t through MLF, when should I add Lysozyme? If the lactic population is below 106, and MLF has started, then use 150-400 ppm of lysozyme now. If the population is above 106, then wait for MLF to complete and immediately add lysozyme.
I added 300 ppm of Lysozyme to a stuck Chardonnay fermentation to help control VA. Will it be possible to get the wine to complete MLF? Yes.
When lysozyme is added to juice or must it will react with pectin, polyphenols and solids. This interference will not affect lysozyme s ability to work against the target population. It will, however, lead to an eventual decrease in activity.
If MLF is desired after lysozyme treatment, add 25 g of bentonite per 100 l of wine to help reduce residual activity and inoculate with a strong ML starter culture. How ...
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
