If the haze persists you can test to see if the wine still contains excess pectins by adding your wine to methanol at a rate of 1:4. If a heavy, off-white precipitate forms the wine contains excess pectins and it should be treated again with pectic enzymes. If the problem continues it will most likely be necessary to filter the wine.
