In case someone wants to try making a wine brew, I thought I would show the progress of the 3 x 5 gallon must buckets mulberry + Sugar at 72 hour mark after adding yeast and just completed stirring. This is considered the aerobic phase when most of the alcohol is produced and the yeast are peaking in activity. I stirred it with a long wooden handle knife and it's enough solids to still stand up in the solution with the mulberries surrounding it. Hydrometer is also present in the must floating to a degree. I just place a linen cloth over the 3 buckets to help keep bacteria, other yeast, etc. from falling in the buckets. This will proceed for another about week and 1/2 and then remove most of the sediment/dead yeast/ etc. that will be left on the bottom and place in air lock (or you could put in any bottle with loose top if doing like the guy in the youtube video) bottle and rack multiple times for improved clarity and decrease chance of sediment from altering taste or drink when ever you desire including the sediment as it will not hurt most like me except for increase chance of passing gas forming yeast through the intestine. ha. Also, most of the alcohol will be made before 14 days from yeast inoculation.
