A few days ago I saw a new brand of butter at a local store - "Shannon Gold", and the label said it was "Irish style". This is presumably to compete against Kerrygold butter, one of the richest, most flavorful butters you can buy in the USA; Kerrygold butter is made from cream that was imported from Ireland, its renounced richness presumably a result of the extremely nutritious grass that Irish cows graze on.
