are simple: the type of drink, the ingredients, and the storage conditions all play a role in determining its shelf life. For example, a gin and tonic will last longer than a cream-based cocktail, because cream can curdle and separate over time. This means you'll want to consume that Piña Colada within a day or two, max!
Now, let's talk about 酸性 (that's acidity, for non-chemistry buffs!). Drinks with high acidity, like those containing citrus juice, will last longer than those without. This is because the acidity acts as a natural preservative, keeping bacteria and other microorganisms at bay. So, if you've got a Margarita or a Whiskey Sour in the fridge, you can safely store it for a few days.
