There are tests available for L-Lactic Acid to tell if your MLF is actually underway, and also for Malic Acid, to tell when MLF is completed without having to guess when the bubbles stopped, and so you don't leave your wine unprotected needlessly. The tests don't require equipment, take only 4 minutes, and are sensitive to 30 mg/L. This may sound like a commercial, but they really work, and are used by commercial and by amateur winemakers. There's more information at www.accuvin.com, or you can email me directly with any questions.<br /><br />Thanks, Reluctant Chemist.Reluctant Chemisthttps://www.blogger.com/profile/09800169527774390507noreply@blogger.comtag:blogger.com,1999:blog-17085756.post-60115737604323506692008-10-13T20:52:00.000-04:002008-10-13T20:52:00.000-04:00RC, I have to admit, I depend on time more than an...RC, I have to admit, I depend on time more than any test to confirm MLF. By keeping innoculated wine in carboys through the spring and summer as the basement temperature warms, and then not bottling til the next vintage of grapes arrive in the fall and winter, I have had no problem with post-bottling fizz. So, I'm only hypothesizing that this is a suggestion my MLF is completed.jorrayhttps://www.blogger.com/profile/08091347621678409530noreply@blogger.comtag:blogger.com,1999:blog-17085756.post-75181698829702015522007-11-07T22:14:00.000-05:002007-11-07T22:14:00.000-05:00Hi, Regarding MLF, one other parameter to watch i...Hi, Regarding MLF, one other parameter to watch in addition to Free SO2 level and temperature, is pH. It's really tough to get MLF going below pH 3.4. By the way, how do you monitor your MLF to mank sure it has begun, and to know when it has completed?Reluctant Chemisthttps://www.blogger.com/profile/09800169527774390507noreply@blogger.comtag:blogger.com,1999:blog-17085756.post-61039165616052777692007-04-10T23:07:00.000-04:002007-04-10T23:07:00.000-04:00Dave,My new move this year was to add the Acti-ML ...Dave,<BR/>My new move this year was to add the Acti-ML nutrient. I won't be able to say if it helped for a month or two though. Watch temperature too.jorrayhttps://www.blogger.com/profile/08091347621678409530noreply@blogger.comtag:blogger.com,1999:blog-17085756.post-86339596878080035582007-04-10T11:52:00.000-04:002007-04-10T11:52:00.000-04:00I'm going to start malolactic fermentation this we...I'm going to start malolactic fermentation this weekend on my 2006 grapes (several year kit wine maker, first year grape wine maker). I tried a few months ago and it didn't take. I found out later my SO2 was too high. I'm trying again using Lalvin VP41, a more tolerant bacteria. Do you have any tips for a first timer?<BR/><BR/>Thanks,<BR/>DaveDave Lhttps://www.blogger.com/profile/06113631614236083317noreply@blogger.com
