The Big Long List of Wine Additives

There’s a lot that goes into good wine, but wine additives don’t have to be one of them.


If you’re just now joining SECCO Wine Club, you’ll quickly find we’re not a big fan of unnecessary additives. In fact, from grape to glass we ensure no toxins, extra sugar, or unnecessary additives make their way into our wines. We do this for two reasons. First, because we dry farm our grapes to ensure the truest expression of flavor. Our vineyards are in Tuscany and we love that Italian wine flavor, so why alter it with additives! 


Secondly, because some of the approved additives are…questionable. You’d be shocked at just how many additives vintners are allowed to use in their wines. Some of them are pretty common, however some of them are downright shocking.


Different Types of Wine Additives


Additives are often split into two categories: common and corrective. The common ones are generally used to assist with standard wine making practices. Corrective additives are where things get a little dicey. The name itself tells you they’re only used when something needs to be “corrected,” meaning that something wasn’t quite right.


The International Organization of Vine and Wine differentiates even further between Food Additives and Processing Aids. Processing aids don’t have to be presented on labels and they’re not always present in the finished wine. If they are, the amounts are generally negligible. These are substances or materials used for technical purposes during treatment or processing. 


Food additives, however, are compounds that end up staying in the wine. At first that doesn’t sound so scary. But the OIV describes them as, “any substance not normally consumed as a food by itself and not normally used as a typical ingredient of the food, whether or not it has nutritive value.” That’s a little scarier. Plus, these aren’t necessarily required on labels either. Speaking of which…


What Are Wine Labels Required to Display?


Honestly, not a lot. In fact, according to the Alcohol and Tobacco Tax and Trade Bureau, there are only eight items that vintners are required to display:


  1. Brand Name or Producer Identification
  2. Bottler’s Name and Address
  3. Varietal Designation, Class/Type
  4. Appellation of Origin, Country of Origin
  5. Alcohol Content
  6. Vintage Date
  7. Net Volume of Contents
  8. Sulfite Declaration 
  9. Health Warning Statement


Only one of those items has anything to do with additives. Considering how many additives might have been used, that seems like a crazy amount of items to leave off a label. 


At SECCO Wine Club, we like to be transparent about what goes into our wines. We use a few of the more basic items from the list below, but anything that’s unnecessary or controversial gets a big NO from us. 


If, however,  you’re still curious, here’s a giant list of additives you may find in wines.

Final Thoughts


This list isn’t meant to scare people away from wines that use additives. Some of these substances have been used to make wine for centuries. In fact, did you notice that both yeast and water were on that list? Duh!


What this list should tell you is that there’s a LOT that goes into wine. Because of that, you should have the option to know what those items are. Speaking of which…


One of our goals is to promote Wine Education!


As we continue to make low-carb wine that’s free of residual sugar and toxins, we want to promote more wine education. Everyone should be able to choose what they put into their bodies. That all starts by understanding what’s actually IN your food and beverages. 


That was one of the biggest inspirations for our PALO61 series. It’s the only wine on the market with a nutrition label, giving you the ability to see what’s in your wine and, more importantly, what isn’t.


If this list was enough to help you ditch the sugary, additive laden bottle you’ve had smuggled away, then great! Be sure to check out our PALO61 bottles for a healthier option that won’t leave you feeling guilty.
