Can you open lid during wine fermentation?

Does fermentation need to be airtight? No! In fact, primary fermentation should never be airtight because you run the risk of blowing the top off of your fermenter or breaking it completely. As carbon dioxide is created during the fermentation process, an incredible amount of pressure can build up over time.
Does wine fermentation need oxygen?
Oxygen is the enemy of wine. This is well understood. Leave the cork out of a bottle, or the bung out of a barrel, for long enough and even the most stalwart wine will sour and decay. And yet oxygen exposure during fermentation and élevage is essential to produce a stable and long-lasting wine.

Is it better to ferment wine with a lid on?
The Benefits of Open Fermentation. Lids can help trap heat and, depending on your ambient temperature outside the fermenter, your wine could get too hot with a lid in place. Most commercial wineries will ferment red wines in open containers to allow heat to escape and to have better access to the cap.
What are the benefits of open fermenting wine?
