Natural Wines, Low or Minimal Intervention Wines and the Use of Additives

Have you ever examined a wine label for ingredients? Or have you assumed that wine is simply made with grapes with no additives except possibly sulfites?  Because there is no requirement for wine labels to include a list of additives, unlike other food products, consumers have no idea what has been added to wine. The one exception is that the phrase “contains sulfites” is required to be printed on the label. Information on additives/ingredients is important. For example, people who are vegan need to know if there are animal byproducts used in the winemaking process. Other people may be allergic to certain additives.  In an effort to inform consumers over the past 20 years there has been classifications of wines that address, in part, the additives/ingredient issue. This post will review the spectrum of classifications. At one end of the spectrum are natural wines and at the end are commercial wines.  In between the two ends are low or minimal intervention, biodynamic, organic and sustainable wines.

This post will not examine whether a certain classification of wine is healthier than others, as there is little scientific study in this area. There are empirical analyses. Note, however, it has been established that people respond differently to certain aspects of wine: (i) alcohol, (ii) natural occurring chemical byproducts associated with the production of wine and (iii) additives. This post provides a baseline of information so consumers can taste wines from classifications described below and decide if a type of wine is more or less agreeable to drink.

Natural wines

Because of the lack of transparency, it is difficult to assess whether a wine is natural or low/minimal intervention. Many producers use these terms to describe their wines without  certification from an objectively established standard. Although there is little government regulated certification, there are several ways to determine if a wine meets an objectively established natural or low/minimal intervention wine standard.

With the exception of France, there has been no attempt to provide a government sponsored certification for natural wines. See Jamie Goode’s article “France Launches Official Natural Wine Certification. Does Anyone Really Want It”  https://www.winemag.com/2020/05/19/natural-wine-definition-france/.   As Goode points out there is not a consensus among natural winemakers that certification is a good idea as it is against the spirit of natural wine.  Certification with its concomitant bureaucracy may limit the freedom natural winemakers currently enjoy. There is a further concern that companies in search of an opportunity will go through the motions and meet the bare minimum of standards.

How then does one determine whether wine advertised as natural or low/minimal interventi0n is in fact as advertised. One way, which is not practical to most consumers, is to visit and interview the winemaker and observe the farming and production processes. Another way is to review a list of wines included in certain associations that have established criteria for natural or low/minimal intervention wines.  There are two such associations: RAW WINE and Triple A Movement. Below is a discussion of these two associations.

RAW WINE

RAW WINE http://www.rawwine.com. is a compendium of low intervention organic, biodynamic and natural wine growers and makers worldwide. RAW WINE members meet the following  requirements: (1) organic grapes grown without the use of chemicals, (2) wine produced by hand using artisanal techniques,  (3) wine made with traditional processes that enable balance, (4) create a living wine, with low intervention in the cellar, and (5) promote well-being in individuals and communities. RAW WINE goes further by defining natural wine as:

“Natural wine is farmed organically (biodynamically, using permaculture or the like) and made (or rather transformed) without adding or removing anything in the cellar. No additives or processing aids are used, and ‘intervention’ in the naturally occurring fermentation process is kept to a minimum. As such neither fining nor (tight) filtration are used. The result is a living wine – wholesome and full of naturally occurring microbiology.”

RAW Wine sponsors conferences to showcase their members wines. Here is a summary of requirements to participate at a RAW WINE conference:

  • The entirety of the domain from which the grapes are issued must be farmed organically and/or biodynamically (pesticides and herbicides not allowed).
  • Grapes must be hand-harvested.
  • No yeasts may be added, except in the case of the second fermentation of sparkling wines, when neutral yeasts may be used.
  • No blocked malolactic fermentation.
  • No winemaking additives (yeasts, enzymes, vitamins, lysozymes etc.) may be used in the cellar except for low levels of sulfites. Paperwork detailing total levels of sulfites for each wine is provided. RAW WINE includes these levels in its catalogue and website. If no sulfites are added, “no added sulfites” will be included in the catalogue and analyses are provided. Low level of natural occurring total of sulfites will be included with a wine’s information. (Note no sulfite totals may exceed 70 ppm regardless of color or style.)
  • No ‘heavy-manipulation’ has been carried out using winemaking gadgetry such as reverse osmosis, cryo-extraction, spinning cone, etc.
  • No sterile filtration or pasteurization.
  • Most of the wines showcased will not have been fined or filtered. If wine has been fined or filtered, it will be  labeled as such. Only vegan or vegetarian friendly fining agents allowed. (For example, common fining agents added such as gelatin, egg whites and casein are not vegan friendly.)

RAW WINE in its catalogue of wines designates wines made with no sulfites added as 100% natural wines or simply as no sulfites added wine.  Wine made with no additives, but with a trace of sulfites are designated as low sulfites wines and all the other wines do not receive a separate designation unless the wine has been fined or filtered. All these wines are considered natural wines, notwithstanding the differences.

RAW WINES
Some of the wines in my cellar included in RAW WINE’s catalogue. Note, Il Cancelliere and Salvatore Magnoni do not add sulfites to any of their wines; Casebianche does not add sulfites to the bottle of La Matta.

Triple A Movement

The Triple A Movement http://www.triplea.it – Agricoltori Artigiani Artisti (Farmers Artisans Artists) was started in response to the standardization of  wines throughout the world.  The Triple A Movement promotes farmers that produce healthy and ripe grapes with natural agronomic interventions; artisans that do not alter the original structure of grapes and do not alter the structure the wine; and artists that give life to a great wine where the characteristics of the territory and wine are exalted.

According to the Triple A Manifesto, conceived, authored and edited by Luca Gargano, a noted pioneer of natural wines, to obtain a great wine, a producer needs three basic qualities, which are summarized as the three As (agricoltori, artigiani and artisti).

“A” (as farmers) agricoltori: (i) only those wh0 cultivate the vineyard directly can establish a correct relationship between man/woman and vine and obtain healthy and ripe grapes; (ii) exclusively with natural agronomic interventions.

“A” (as craftsmen) artigiani: “artisanal” methods and skills are needed to implement a viticulture and oenological production process that does not modify the original structure of the grape and does not alter that of the wine.

“A” (as artist) artisti: only the “artistic” sensitivity of the producer, respectful of his/her work and ideas, can give life to a great wine where the characteristics of the territory and the vine are enhanced.

Per the Manifesto, Triple A wines may only be created:

  • from a manual selection of future vines, for a real mass selection.
  • by agricultural producers, who cultivate the vineyards without using synthetic chemicals, respecting the vine and its natural cycles.
  • from grapes harvested at physiological maturity and perfectly healthy.
  • from musts to which neither sulfites nor other additives are added. Sulfites can only be added in minimal quantities at the time of bottling.
  • using only indigenous yeasts and excluding selected yeasts.
  • without chemical or physical interventions before and during alcoholic fermentation other than simple temperature control. (Concentration interventions carried out by any method are strictly excluded).
  • maturing on its own “fine lees” until bottling (dead yeasts or residual yeasts and other particles that collect at bottom of the vat of wine after fermentation and aging).
  • not correcting any chemical parameters.
  • not clarifying and filtering before bottling.
  • from the best expression of the terroir to which they belong.

Low/Minimal Intervention Wines

What is the definition of  a producer of  low/minimal intervention wines? Non-interventionist winemakers use as few additives as possible and as little manipulation as they can. http://www.morethanorganic.com/definition-of-natural-wine (“More than Organic”). As More than Organic notes winemakers have to compromise at some point. Where and why they compromise depends upon what they are trying to achieve and how much they are prepared to risk in  order to achieve. There are certain elements that compromise a total non-intervention wine, but as More than Organic notes that making a “perfect natural wine” is difficult to achieve. Sometimes winemakers will achieve this “perfect natural wine” but many times winemakers, as business people, have to improvise in order to prevent the wine from spoiling. Winemakers that adhere to a natural process will intervene minimally and only when necessary.

Importance of Additives in Manipulated Wines

There are producers that adhere to the natural process to the extent that they will not produce a vintage or will sell their wine juice, rather than produce a wine so manipulated that is inconsistent with natural winemaking. I am aware of two EU certified organic producers that refused to manipulate their wine juice for a particular vintage to make it marketable.

Terre del Principe e Le VIgne di Raito
Le Vigne di Raito did not produce wine under its label one year because of a poor quality of grapes which resulted in a substandard quality wine juice. Terre del Principe did not produce wine with certain grapes one year because the grapes were not of sufficient quality.

As one natural winemaker told us, he could take any type of inferior wine juice and make it marketable with the utilization of additives. We had representatives of a two million plus producer explain that their wines are manipulated to taste the same on a yearly basis because their customers expect a consistent product. Further, it is inconceivable that a winemaker responsible for more than two million bottles would inform the owners/producers that there would be no wine, or a limited quantity produced due to inferior grapes or wine juice.  Owners/investors would instruct the winemaker to fix the problem.

Ben Panko in his April 4, 2017 article in the Smithsonian, “The Science Behind Your Cheap Wine”, discusses the importance of additives in mass produced wines.  In his article he quotes passages from Bianca Bosker’s New York Times Bestseller List book Cork Dork,  published in March, 2017. Bosker immersed herself in the world of sommeliers, scientists. restaurants, producers and wine shows to report on these groups obsession of wines. Panko, quoting from Bosker’s book included the following passage, “One of the things that I did was to go into this wine conglomerate [Treasury Wine Estates] that produces millions of bottles of wine per year. People are there developing wine the way flavor scientists develop the new Oreo or Doritos flavor.”

As summarized by Panko, Treasury Wine Estates has what Bosker describes as “sensory insights labs”. There are focus groups that taste a variety of products and the better ones are sampled by average consumers to help winemakers obtain a sense of which sensory profiles would do best in wine stores and restaurants. The winemakers job at Treasury Wine Estates is to manipulate the wine with additives to reflect the sensory profiles that consumers prefer.  So what are additives that are allowed?

In the United States up to 60 different additives are permitted to be used to manipulate wines. There is no requirement to list these various additives on the label. Here is the list of approved  additives: https://www.ecfr.gov/cgi-bin/text-idx?c=ecfr&sid=e616cf652c2a16d768ed4c4873ad2cb0&rgn=div8&view=text&node=27:1.0.1.1.19.12.343.7&idno=27 Here is a description of the impact of  a few of the  additives: tartaric acid to correct natural acid deficiencies in grape juice/wine; sugar to adjust alcohol; egg whites or bentonite (Wyoming clay) to clarify/stabilize wines and remove tannins; isinglass or fish bladder to remove proteins, yeast and other organic particles which are in suspension in winemaking; nonindigenous or cultured yeasts; sulfur dioxide (also referred to as sulfites) to sterilize and preserve wines;  powdered tannins for texture and astringency; gum arabic to soften tannins and reduce astringency to make a red wine more silky; acetaldehyde for color stabilization; activated carbon to assist in fermentation, to clarify and remove color from wine or juice; and the magic potion Mega Purple. Mega Purple is a concentrate made with the rubired grape, a hybrid grape grown exclusively in San Joaquin Valley, CA. A couple of drops of the gooey concentrate is added to red wine to add color, make the wine sweeter and cover up flawed flavors. It is prevalent in wines produced in large quantities at  low-cost, and may be used in some high-end wines. The wine conglomerate, Constellation Wine Company, which created Mega Purple, reportedly sold over 10,000 gallons of it yearly. In June 2020, Constellation sold Mega Purple and related grape concentrate additives to Vie-Del, a California family owned grape  processer and supplier of bulk juices, grape concentrates, brandy, wine and spirits. Although few wineries will admit to the use of Mega Purple, based on its annual sales, it is widely used.

Of the 60 additives, how many are added to natural wines? Both RAW WINE and Triple A allow sulfites to be added to their members wines. RAW WINE allows vegan friendly fining and filtration to be added/used in the winemaking process. Australian certified organic and vegan winemaker, Matt Purbrick, author of Grown and Gathered, in an interview in “The Wayward” discusses when natural wine morphs into a low/minimal intervention wine. Purbrick states as follows: Minimal intervention is often lumped into the same category as natural, but really it has a little more room to move. Minimal intervention wines should still be organic or biodynamic, but small interventions (like small natural tannin or acid adjustments) may still be allowed, and small sulphur additions are more accepted. These are still very naturally made wines, but with a less rigid ‘no-additions’ policy and may utilize some fining or filtration. Minimal intervention is probably the most contentious term out there because some still claim it is a synonym of natural, whereas others agree it represents a slightly more relaxed philosophy.” https://www.thewayward.co/waywardfolk/2019/5/natural-wine-explained.

Made with certified organic or biodynamic grapes versus wine certified as organic or biodynamic

In the above discussion of natural and low/minimal intervention wines there is a requirement that wines are to be made with organically or biodynamically farmed grapes, i.e., meeting USDA or EU organic farming requirements or standards established by Demeter, the organization responsible for establishing biodynamic farming standards. But, meeting these farming standards alone, will not necessarily result in natural or low/minimal intervention wines being classified as USDA certified organic or Demeter certified biodynamic wines. Conversely, USDA certified organic or Demeter certified biodynamic wines will not necessarily meet the natural wine requirements of RAW WINE or Triple A, or even low/minimal intervention wines. Adding to the confusion, wines meeting EU certification of organic wines rarely meet the USDA  certification of organic wines, but EU certified wines may meet RAW WINE and Triple A requirements, however. Confused? Here is an attempt to explain the seemingly incongruous requirements of the various wine certifications. USDA organic certification does not allow the addition of any sulfites, whereas natural and low/minimal intervention wines may include minimal amounts of sulfites. Interestingly, Demeter and EU certified organic allow up to 100 ppm of sulfites to added, which is greater than the amount allowed by RAW WINE and Triple A. To provide a perspective as to the permissible amount of sulfites that may be added to any wine (e.g. mass produced wine): Europe permits up to 210 ppm and the USA permits up to 350 ppm. The type of yeasts used in fermentation differentiates RAW WINE, Triple A and Demeter from USDA certified organic wines. as the USDA certified wines may use natural or organic selected yeasts, but RAW WINE, Triple A and Demeter permit only indigenous yeasts. USDA certified wines may use additives provided that such additives are on the Natural Organic Program approved list. Such additives include sugar, water and acids, which are included in the list of 60 additives described above. These additives are not permitted in RAW WINE, Triple A or Demeter certified wines. Note, EU certified organic wines also permit organic additives, as do low/minimal intervention wines per Matt Purbrick, albeit in a limited basis.

Sustainable Wines

A few words on wines classified as sustainable. This classification focuses less on the practices in the cellar (i.e. additives) but more on farming and business practices. There are numerous groups that provide certifications of which wines meet sustainability requirements. Here is the essence of sustainable winemaking: a process that protects the environment, supports social responsibility and maintains economic feasibility. Sustainable winemaking allows more flexibility with less stringent requirements in the vineyard and cellar than those for natural, low/minimal intervention, certified organic and Demeter certified biodynamic. For example, sustainable winemaking is not prohibited from the use of additives and inorganic pest control measures, provided both are used in moderation and in the case of pesticides, integrated pest control is encouraged as the first line of defense in the vineyard. 

A suggested approach for differentiating “100% Natural Wines” from “Natural Wines with Minimal Sulfites Added” and “Natural Wines with Low/Minimal Intervention”

“100 % Natural Wines”  contain no additives, including no sulfites. For example, wines such as Il Fric and La Matta from Casebianche, Il Tocco and Mossa from Casa di Baal, Ansonia from Cataldo Calabretta, and wines from Il Cancelliere (note, that the above photo of grapes is from Il Cancelliere’s vineyard), Frank Cornelissen, COS and Salvatore Magnoni meet this definition of “100% Natural Wine”. (See RAW WINE website cited above for documentation of these wines as being made free of the addition of sulfites.)

Casa di Baal Tocco
Casa di Baal Tocco

Using RAW WINE as a guide here is a suggested approach: classify wines as either (i) “100% Natural Wines”, meaning no sulfites added or (ii) “Natural Wines with Minimal Sulfites Added” meaning only small amounts of sulfites added, or (iii) “Natural Wines with Low/Minimal Intervention”. “100% Natural Wines” will meet the requirements of RAW WINE. “Natural Wines with Minimal Sulfites Added” will meet RAW WINE and Triple A Movement requirements, but not the no sulfites added requirement of USDA certified organic wines. “Natural Wines with Low/Minimal Intervention” will not meet USDA certified organic standards and more than likely not meet RAW WINE or Triple A requirements. The difficulty with this last group is when do the interventions become so pronounced that the wine should no longer be classified as “Natural With Low/Intervention”? As noted above there is no requirement to list additives on a wine label. This lack of transparency allows wide leeway for producers to assert their wines as low/minimal intervention wines. Matt Purbrick provides some guidance, but in the end he acknowledges that this last classification is fraught with varied interpretations, hence, why he simply classifies his wines as organic. 

So what should I drink?

Drink what you enjoy. A wine that is natural or low/minimal intervention does not necessarily make it enjoyable. Wines without additives are difficult to make, hence, the winemaker has to pay close attention to all aspects of winemaking. There are no shortcuts; and one mistake may ruin an entire vintage.  As pointed out above, many winemakers that adhere to a natural process of winemaking from time to time have to rely upon additives to save a vintage. However, a well made natural or low/minimal intervention wine results in an aromatic wine reflective of the terroir.

Similarly, a wine with many additives is not necessarily unenjoyable. Additives are used to remove certain defects that may occur in the vineyard or in the cellar and to satisfy the sensory profiles of tasting panels. Unlike natural wines, heavily manipulated wines have consistent yearly characteristics that are appealing to certain consumers.  This predictability contrasts with the excitement generated by tasting a less predictable natural or low intervention wine.  For those that are concerned with what is added to wines, the focus should be on natural, low intervention, biodynamic and organic wines.
