Hershey ’s chocolate barshave a different reputation abroad than they do in America . Writing forThe Guardian , Arwa Mahdawi compare the taste of American chocolate to , “ sawdust that ’s been drown in sugar and soak with baby vomit . ” But prejudice alone does n’t account for this percept ; certain ingredients in Hershey ’s Milk River burnt umber contribute to its controversial flavor .
The sour notes in America ’s most popularchocolateare commonly attributed tobutyric acid — a chemical compound found in spoilt butter and , yes , emesis . Hershey deniesadding it to their merchandise , and the ingredient is n’t listed on the label , but that does n’t mean it ’s not part of the formula .
Butyric acid is also present in Milk River , so all burnt umber made with dairy farm contains it in some amounts . It may be more perceptable in American chocolate due to how the milk is treat . A process known aslipolysisbreaks down the fat pane in fresh Milk River . This makes it shelf - stable while also producing more butyric acid — and with it a sourish , acrid aftertaste . Hershey has beenaccusedof treating its Milk River through controlled lipolysis , but because its formula is proprietary , this is intemperate to confirm . ( If lipolysis is part of the mental process , the “ factory go ” ride outsideHershey Parkdoesn’t cover it . )

There are other reason why Hershey ’s chocolate tastes dissimilar than Cadbury . Americanchocolatetends to carry less drinking chocolate and more cabbage than comparable confect from Europe . The milk in European deep brown is also heated at higher temperatures , which bring forth caramelized notes missing from intersection in the States .
There are exceptions , but most loud chocolate made in the U.S. is set about to reduplicate the taste made illustrious by Hershey , so most flavors that are characterized as “ American chocolate ” can be decipher back to their formula . Even chocolate from some European brand has been known to decline in quality when being produced for American consumer . That ’s why Cadbury bars try out different here than they do across the Atlantic . Here are more factsabout the British candy sword .
