What about taste?

Grass-finished meat differs from grain-fed meat in taste, aroma and texture. But which is better is a matter of preference. Taste and aroma panelists in a British study described grass-fed beef as having a “green” aroma and grain-fed beef as “soapy”.

The following is a quote from Daley. et.al., A review of fatty acid profiles and antioxidant content in grass-fed and grain-fed beef. published in Nutrition Journal 2010, 9:10 .http://www.nutritionj.com/content/9/1/10.

“…..in a study where British lambs fed grass and Spanish lambs fed milk and
concentrates were assessed by British and Spanish taste panels, both found the British lamb to have a higher odor and flavor intensity. However, the British panel
preferred the flavor and overall eating quality of the grass-fed lamb, the Spanish panel much preferred the Spanish fed lamb . Likewise, the U.S. is well known
for producing corn-fed beef. Taste panels and consumers who are more familiar with the taste of corn-fed beef seem to prefer it as well. An individual usually comes to prefer the foods they grew up eating, making consumer sensory panels more of an art than science”.
