I see two errors....
1) sg numbers below 1.000 are wrong. should be .998 rather than .098
2) I don't agree with the location of the comment "high alcohol level in this range". If the starting sg is 1.020, a final sg of .986 means 4.5%. Not high alcohol.
Two comments...
1) I have never seen a wine drop below .990. Find it tough to believe that one would reach .980
2) I think the starting sg comment needs to cover a wider range. 12% alcohol means sg 1.082, and final sg .992. Also many people believe that fruit wines should typically be under 12%.
