#Sulfites January 24

We may earn money or products from the companies mentioned in this post.

In January 2026, many of us will take part in the 30-Day Label Coach4aday Challenge. Each day we will share a label from a food product and share info about one of the ingredients. The goal is simple—read food labels, research unfamiliar ingredients, and become more intentional about what you’re putting into your body, building awareness that can lead to healthier, more mindful eating. Today my post is on SULFITES.

Many of my friends have discriminating palates for wine. Sulfites are commonly added to wine to act as preservatives, helping prevent oxidation and inhibit the growth of unwanted bacteria and yeast. They help maintain freshness, flavor stability, and color over time. While most people tolerate sulfites well, a small percentage—especially those with asthma—may be sensitive to them.

Label-30 Day Challenge Guidelines

As with previous challenges, participants are encouraged to adapt the guidelines to fit their own circumstances. If you can, commit to sharing an ingredient from a food label during the month of January.

1. Locate a label on a food product and research an ingredient you might not be familiar with.  
2. Share with a challenge partner if you have one what that ingredient is.
3. Join the conversation by posting on social media with the hashtag #Coach4adayChallenge

January 24th-Sulfites

In commercial wine production, the amount of added sulfites varies by style. Wines with deeper color, such as reds, generally require fewer sulfites than lighter or clear wines like whites. It’s also important to note that all wines naturally contain sulfites produced during fermentation. Most experts agree that sulfites for many is not a health risk.
