The type of cheese is the biggest consideration - hard cheese will last longer and is less likely to pose a health risk, while soft and fresh cheeses should remain refrigerated and only be left out for two hours at most. No matter the cheese, leaving it out for more than two hours may change the quality and taste.
To keep yourself safe from bacterial growth or spoilage, you should only keep cheese out for four hours, according to Adam Brock, director of food safety, quality, and regulatory compliance at Dairy Farmers of Wisconsin.
Soft cheeses such as cream cheese, cottage cheese, shredded cheeses, and goat cheese must be refrigerated for safety. As a general rule, hard cheeses such as cheddar, processed cheeses (American), and both block and grated Parmesan do not require refrigeration for safety, but they will last longer if kept refrigerated.
The U.S. Department of Health doesn't recommend keeping any perishable food sitting out of the fridge for more than 2 hours — and that's definitely the case for soft cheeses, like cottage or cream cheese, brie, or fresh mozzarella.
03/7Use a cheese paper/bag
To keep your cheese fresh for as long as possible, cheese bags or cheese paper is the best way to store it. It's porous, so it protects the cheese from air exposure while still allowing it to breathe.
How long can cheese sit out before it becomes unsafe to eat? For the best taste and quality, cheese should not be left out for longer than two hours at room temperature. Hard cheeses can be left out longer without becoming unsafe, but the quality and taste may change.
Cheese will usually become unpalatable far before it becomes dangerous, so there's no need to stress. With many harder cheeses, you can even scrape off any blue, gray, or green mold that's growing. That said, if you ever see red or black mold, your cheese is a no-go (and your fridge could use a thorough sanitizing).
Serving mozzarella di bufala
To taste authentic buffalo mozzarella, its temperature must not exceed about 64-68°F (18-20°C) when consumed. Keeping it in the refrigerator would compromise its qualities and the mystical experience of tasting it.
A pungent cheese will still taste pleasant to a connoisseur. When it has gone bad, it will taste overly bitter or sour, or have a musty quality to it, like drinking water from a moldy pipe. And if a mild cheese all of a sudden has some character to it, don't assume you just aged your own cheese. Just throw it away.
According to the US Food and Drug Administration, refrigerated foods, including milk, should never be out of the fridge at room temperature for longer than two hours. That window closes quickly if the ambient temperature rises.
Unfortunately, as mouthwatering as those leftover slices may look in the morning if you accidentally leave pizza out on the counter overnight it's best to throw it away.
Fresh mozzarella balls are sold in a brine, whey or water solution to help them retain their moisture and shape.
Store all types of cheese in the vegetable crisper of the refrigerator, where the temperature is cold and stable. Use a fresh piece of plastic wrap or wax paper to rewrap cheese after each use. The length of time you can keep cheese differs by variety; in general, the harder the cheese, the longer it will last.

Recommendations for its shelf life include: Unopened and refrigerated: Up to three weeks beyond the use-by date, depending on refrigeration temperature, or, according to some experts, up to 70 days after the production date.
According to Sarah Hill, Manager of Cheese Education and Training for the Wisconsin Milk Marketing Board, cheese can be left at room temperature for up to two hours, as can all perishable foods.
"Leaving cheese out overnight may impact the quality of the product, but would not—in most cases—result in a food safety issue," explains Adam Brock, director of technical services at Wisconsin Milk Marketing Board. If anything, there's a good chance you're over-refrigerating your cheese.
The main causes of cheese spoilage are microorganisms (bacteria, yeasts, and molds) that can grow during the manufacturing process or all along the shelf life, modifying sensorial properties, aroma, structure, and color of foodstuffs.
How Long Can Eggs Sit Out? According to the USDA, refrigerated eggs should not be left out for more than two hours. “Eggs are stored cold right after the hen lays the eggs.
Some types of cheese and meat products require refrigeration and others do not. Some cheeses and meats have a low moisture content, higher level of acid, have been smoked, or contain ingredients that help control bacterial growth.
Ideally, cheese should be kept between 35 and 45 degrees Fahrenheit. Freezing can cause the texture to degrade, so the best place to store cheese is as far from the freezer as possible. Keep it in the vegetable drawer or on a bottom shelf where the temperature is consistent but not too cold.
Feta is very simple – a fresh cheese whose curd is pressed and then preserved in salty brine. Stored this way, Feta can last for months, which would have served ancient people well in the days before refrigeration. Milk: Originally, Feta would have been made from sheep's or goat's milk.
In addition, fresh mozzarella is stored in a watery whey that will need to be drained before being used.
This can happen when you cut your curd into pieces that are too small and so release too much moisture or when the mozzarella is stretched too much. Try and stretch your mozzarella as little and as gently as possible until you achieve a smooth texture and then form into a ball.
