Now, give it the eyeball test. Fresh feta is creamy white with a slightly crumbly texture; it might have a few tiny holes from aging, but that’s normal. When things go bad, you’ll see fuzzy growths in shades of green, black, or pink—or a slimy, wet shine that’s not just brine.

If the texture feels mushy or sticky like a forgotten sponge, that’s a hard pass. Your feta should crumble, not disintegrate into goo.

The Brine Test—Yes, It’s a Thing

Most feta swims in a salty brine, which is its superhero cape for staying fresh. If the brine has turned cloudy, bubbly, or developed a weird film, the cheese is likely fermenting in a not-so-delicious way.

Give the liquid a sniff too—if it smells yeasty or funky (like a forgotten kombucha experiment), it’s time to part ways. A happy brine smells clean and salty, like the sea after a storm.
