Should I keep the stopper on decanter when filled with wine, or am supposed to let it breathe?

The answer depends on the type of wine, age, and personal preference. Here are some general guidelines:

Red Wine:

- Young Red Wine (less than 5 years old):

- For young red wines that are meant to be consumed relatively soon, leaving the stopper on the decanter might be preferable. This helps preserve the vibrant fruit flavors and aromas and prevents excessive oxidation.

- Aged Red Wine (more than 5 years old):

- Aged red wines often benefit from decanting and allowing them to "breathe" for a while before consumption. Decanting can help open up complex aromas and flavors, soften tannins, and smooth out the口感. The recommended breathing time may vary from 30 minutes to several hours, depending on the specific wine. It's worth experimenting to find the optimal breathing time that suits your taste.

White Wine and Rosé:

- White Wine and Rosé:

- In general, white wines and rosé wines tend to be consumed chilled and are enjoyed for their fresh, vibrant flavors and aromas. They usually aren't decanted and are best when consumed young (within a few years). Leaving the stopper on the decanter is advisable to maintain their liveliness and prevent unnecessary oxidation.

It's important to note that these are general guidelines, and you might come across specific wines that might benefit from slightly different approaches. As your taste and experience with different wines grow, you might develop your own preferred methods for enjoying decanted wines. If in doubt, consult a sommelier or wine expert for recommendations specific to the wine you intend to consume.
