How long does MLF last and when do you know it is done?

It can last up to 3 months depending on temps, if you added mlf nutrient, and what the specifics of your wine was like as in PH and ta cause these factors can slow down MLF just like they can throw off a standard fermentation. You can find out if its done by doing a chromatagraphy test.

Paper chromatagraphy is a test kit to test completion of mlf.Go to www.morewinemaking.com
You can also opt to purchase an Accuvin Malic Acid Test Kit to test when MLF has completed. It's less expensive than chromatography if you only test occasionally.

Rob,

This is one source for the malic acid test kit: http://www.finevinewines.com/Home-Wine-Making-Equipment-Testing.asp

It works very simply by drawing out a small wine sample into a plastic sqeeze tube. The sample is applied to a test strip and after 4 minutes the color is compared to a color chart. Much like pH strips, but none of the problems inherent with reading pH strips because the colors are completely different than wine color.
