Whether expired beer can be cooked depends on how long it has expired. If it has just expired for a day or two, it can be used for cooking. However, if the expired beer is turbid, stale or deteriorated, it is best to throw it away immediately.
Generally, the shelf life of beer on the market is 12 months, while that of draft beer is only a few days, especially in summer. Many acids contained in beer beyond the shelf life are easy to oxidize and polymerize with protein, which makes the beer turbid; Or because the water quality is not good, it is fermented by microorganisms during filling and becomes sticky and rancid.
Therefore, when we eat beer, we must pay attention to the shelf life. If it is overdue, we must discard it.
Use of expired beer:
1, flowers
Beer can also keep flowers fresh, because beer contains nutrients such as ethanol and sugar, so adding a little beer to the container where flowers are inserted can prolong the fresh-keeping period of flowers.
Step 2 wash silk clothes
Washing silk clothes with beer can make them smooth and bright and restore their original appearance. First pour the beer into cold water, then soak the washed clothes for about fifteen minutes, then rinse and dry.
3, clothes add color
Soaking dark clothes in water with some beer can soften them and restore their original color. New clothes don't change color easily after soaking.
Step 4 clean the glass
It is a good way to clean the glass with beer. Because beer contains alcohol and is a colloidal solution, the alcohol in it will evaporate quickly and the glass will become clean and bright.
