What are the little flies around wine?

Answered by Brandon Riddell

The little flies you may notice around your are most likely fruit flies. These small insects are commonly found around overripe fruit and vegetables, as well as anything that contains fermenting sugars, including alcoholic beverages. As an expert sommelier and brewer, I have encountered fruit flies numerous times in my career, and I understand the reasons why they are attracted to wine.

Fruit flies have a keen sense of smell, and they are particularly drawn to the aroma of fermenting sugars. This is why they are commonly found around overripe fruit and vegetables, as these produce natural sugars that have begun to ferment. When it comes to wine, fruit flies are attracted to spillages, dregs left in the bottom of , and residue in sinks and drains.

One of the reasons fruit flies are attracted to wine is because of the leftover sugars in the drink. Even after fermentation, there may be residual sugars present in the wine, especially in sweeter varieties. These sugars provide a food source for fruit flies, making the wine an appealing target for them.

Furthermore, fruit flies are attracted to the aroma of wine. The complex bouquet of different flavors and aromas in wine can be enticing to these insects. They are particularly drawn to fruity and floral notes, which are often present in many wines. This is why you may notice fruit flies hovering around your glass or bottle of wine, especially if it has been sitting out for some time.

In my experience, fruit flies can be quite persistent and annoying when it comes to wine. They can quickly multiply and become a nuisance, especially in warmer climates or during the summer months. It is essential to take measures to prevent their presence and keep them away from your wine.

Here are some tips to help you deal with fruit flies around your wine:

1. Cleanliness is key: Make sure to clean up any spills or drips of wine immediately. Fruit flies are attracted to even the tiniest amount of sugary residue, so keeping your wine area clean is crucial.

2. Store wine properly: Seal your wine bottles tightly with cork or screw caps to prevent fruit flies from accessing the wine. Additionally, store your wine in a cool and dry place, as fruit flies are less likely to be attracted to chilled environments.

3. Use covers or screens: If you are enjoying wine outdoors or at a picnic, consider using covers or screens to protect your glass or bottle from fruit flies. This can help to keep them away and allow you to enjoy your wine without any unwanted guests.

4. Empty and clean drains regularly: Fruit flies can breed in drains and sinks, so it is important to regularly clean them and ensure there is no residue or standing that could attract these insects.

5. Fruit fly traps: If you are dealing with a persistent fruit fly problem, you can set up fruit fly traps near your wine area. These traps typically consist of a container with a sweet liquid bait that attracts and traps the flies. They can be effective in reducing the fruit fly population.

While fruit flies can be a nuisance around wine, there are steps you can take to minimize their presence. By practicing good hygiene, storing wine properly, and taking preventive measures, you can enjoy your wine without the annoyance of fruit flies.
