Interesting.                                                                    
                                                                                
At one point, many years ago, recommendations were that a small                 
amount of tartaric acid be added to sugar syrup to invert the                   
sucrose.                                                                        
                                                                                
Articles I have read indicates that this practice tends to cause                
dysentary and is no longer recommended. Moreover, acid processed                
syrups are known to cause bee mortality.                                        
                                                                                
I wonder if acetic acid -- the main ingredient in vinegar -- other              
than water,  is also detrimental?
