Racking a wine at less than 1.010 SG can cause the yeast to go into shock and possible lead to a stuck fermentation. After a certain amount of time, the yeast inside the beer will start to die off in a process called autolysis which essentially means ‘self-destruction.’ The yeast cells burst apart when they die and the contents released can contribute to several off-flavors, none of which are pleasant.
