Depends how careful you were when making it. I wouldn't keep such a thing more than 4 days even in fridge.
1 month max.
If you keep iot in brine in fridge, at least a month
Feta Cheese Selection and StorageThe finest feta cheese should be purchased direct from its brine bath. If it is pre-packaged, it should have some of the brine in the packaging to keep it moist. Feta cheese is best when eaten fresh, so always check the date. If you will not be consuming it immediately, store feta cheese in a brine or milk bath. The milk bath will reduce the saltiness and help keep the cheese moist and mild in flavor. Properly stored in brine or milk and refrigerated, feta cheese will last up to 3 months. Feta cheese is not a candidate for freezing.
