I am Greek-born and raised and can only use Greek feta, Made in Greece. I really don’t like the French fat-free feta, for example, fat-free feta does not exist in Greece. I also don’t buy the crumbled feta in plastic containers sold in supermarkets, I find it too dry and flavorless. My advice is: Always get a block of feta in brine. You can find good feta at Shoprite, Whole Foods, etc. The Greek brands of feta I usually get are DODONI and MT VIKOS. Local Mediterranean grocery stores will have feta in brine. You can order online from Titan Market in Astoria, NY. Bulgarian feta is also good and might be available in these markets. Trader Joe’s also has Greek feta block in brine.
