Malolactic Fermentation

Is there an easier test than a malolactic fermentation paper chromatography test? Is there a rough time window for it to happen under certain temperatures?

I have heard that Accuvin is much easier to use and take only few minutes to get a more accurate result than the Chromatography test kit. I just order one kit of Accuvin to compare the results with the regular chromatography test on the same wine. Check this link

As for the estimated time to complete the MLF it's very difficult to say. If all the variable are constant and the wine are in the proper numbers range for a MLF you should be near completion after 1 months if the temperature is 20-22 Celcius all the time. This is a rough estimate from my own experiences over the years. You should wait a bit longer to be sure and check your bung for any activity.
