SUPPLEMENTARY INFORMATION:
Background on Viticultural Areas
TTB Authority
Section 105(e) of the Federal Alcohol Administration Act (FAA Act), 27 U.S.C. 205(e), authorizes the Secretary of the Treasury to prescribe regulations for the labeling of wine, distilled spirits, and malt beverages. The FAA Act provides that these regulations should, among other things, prohibit consumer deception and the use of misleading statements on labels and ensure that labels provide the consumer with adequate information as to the identity and quality of the product. The Alcohol and Tobacco Tax and Trade Bureau ( printed page 46472) (TTB) administers the FAA Act pursuant to section 1111(d) of the Homeland Security Act of 2002, codified at 6 U.S.C. 531(d). In addition, the Secretary of the Treasury has delegated certain administrative and enforcement authorities to TTB through Treasury Order 120-01.
Part 4 of the TTB regulations (27 CFR part 4) authorizes TTB to establish definitive viticultural areas and regulate the use of their names as appellations of origin on wine labels and in wine advertisements. Part 9 of the TTB regulations (27 CFR part 9) sets forth standards for the preparation and submission of petitions for the establishment or modification of American viticultural areas (AVAs) and lists the approved AVAs.
Definition
Section 4.25(e)(1)(i) of the TTB regulations (27 CFR 4.25(e)(1)(i)) defines a viticultural area for American wine as a delimited grape-growing region having distinguishing features as described in part 9 of the regulations and, once approved, a name and a delineated boundary codified in part 9 of the regulations. These designations allow vintners and consumers to attribute a given quality, reputation, or other characteristic of a wine made from grapes grown in an area to the wine's geographic origin. The establishment of AVAs allows vintners to describe more accurately the origin of their wines to consumers and helps consumers to identify wines they may purchase. Establishment of an AVA is neither an approval nor an endorsement by TTB of the wine produced in that area.
Requirements
Section 4.25(e)(2) of the TTB regulations (27 CFR 4.25(e)(2)) outlines the procedure for proposing an AVA and allows any interested party to petition TTB to establish a grape-growing region as an AVA. Section 9.12 of the TTB regulations (27 CFR 9.12) prescribes standards for petitions to establish or modify AVAs. Petitions to establish an AVA must include the following:
Petition To Establish Tryon Foothills AVA
TTB received a petition from Cory J. Lillberg, vineyard manager of Parker-Binns Vineyard, proposing the establishment of the "Tryon Foothills" AVA in Polk County, North Carolina. The proposed Tryon Foothills AVA covers approximately 176 square miles and is not located within any other established AVA. There are five commercial vineyards covering a total of approximately 77.70 acres within the proposed AVA, as well as four wineries.
According to the petition, the distinguishing features of the proposed Tryon Foothills AVA are its topography and climate. The proposed AVA is located on the western edge of the Inner Piedmont region of the Blue Ridge Mountains, which is described as a region of low mountains and rolling hills. Within the proposed AVA, the average elevation is 988 feet, while the maximum elevation is 1,656 feet and the minimum is 712 feet. The petition states that the topography of the proposed AVA contributes to the creation of a thermal belt. At night, warm air that has accumulated in the higher elevations becomes cooler and sinks. As the cool air sinks, it displaces warmer air at lower elevations. The warm air settles on the mountain slopes above the cascading cooler air and creates a warmer layer of air above the cooler air. This warmer layer is known as a thermal belt.
Using the Winegrape Climate/Maturity Groupings classification system,[1] the entire proposed Tryon Foothills AVA falls into the "Hot" category, which is defined as a region with an average growing season temperature between 67- and 72-degrees Fahrenheit (F). The average growing season length within the proposed AVA is 200-210 days. Ninety-five percent of the proposed AVA has average annual growing degree day (GDD) [2] accumulations in the very warm Region V category of the Winkler scale, while the remaining 5 percent of the proposed AVA is in the slightly cooler Region IV. According to the petition, the "Hot" region of the proposed AVA makes it suitable for growing grape varietals such as Zinfandel, Grenache, and Cabernet Sauvignon.
The petition states that, in general, the regions to the west, northeast, and northwest of the proposed AVA are cooler and have a greater range of average temperatures than the proposed AVA. The regions to the west and northwest mostly fall into the "Warm" category of the Winegrape Climate/Maturity Groupings classification system, have average growing season lengths of between 180 and 190 days, and have average annual GDD accumulations that place them in Region III of the Winkler scale.
Approximately 68 percent of the region to the northeast of the proposed AVA falls into the "Hot" category of the Winegrape Climate/Maturity Groupings classification system. However, unlike the proposed AVA, approximately 22 percent of the region is also in the cooler "Warm" category. The majority of the region to the northeast has an average growing season length of 190-200 days and average annual GDD accumulations that place it in Region IV of the Winkler scale.
The proposed AVA and the region to the east have approximately the same average annual temperatures, but the region to the east has a lower average minimum temperature. While the region to the east is also mostly in the "Hot" category of the Winegrape Climate/Maturity Groupings classification system, similar to the proposed AVA, it does also have some areas that are in the "Warm" category. The average growing season length in the region to the east ( printed page 46473) is 200-210 days, and approximately 82 percent of the region is in Region V of the Winkler scale.
The region south of the proposed AVA is warmer, as temperatures grow progressively warmer the farther south one travels from the proposed AVA. Ninety-seven percent of the region is in the "Hot" category of the Winegrape Climate/Maturity Groupings classification system. While the majority of the region also has a growing season length between 200 and 210 days, the region has some areas with longer growing seasons that range from 210 to 220 days. The majority of the region is in Region V of the Winkler scale, but unlike the proposed AVA, other parts of the region are classified as Regions II and III.
Notice of Proposed Rulemaking and Comments Received
TTB published Notice No. 229 in the Federal Register on January 5, 2024 (89 FR 716), proposing to establish the Tryon Foothills AVA. In the notice, TTB summarized the evidence from the petition regarding the name, boundary, and distinguishing features for the proposed AVA. The notice also included information from the petition comparing the distinguishing features of the proposed AVA to the surrounding areas. For a detailed description of the evidence relating to the name, boundary, and distinguishing features of the proposed AVA, and for a detailed comparison of the distinguishing features of the proposed AVA to the surrounding areas, see Notice No. 229.
In Notice No. 229, TTB solicited comments on the accuracy of the name, boundary, and other required information submitted in support of the petition. The comment period for Notice No. 229 closed on March 5, 2024. TTB received two identical comments in response to Notice No. 229. However, both comments consisted only of bank statements from a South African bank account and are not relevant to the proposed AVA. Therefore, neither comment was posted to the public docket.
TTB Determination
After careful review of the petition, TTB finds that the evidence provided by the petitioner supports the establishment of the Tryon Foothills AVA. Accordingly, under the authority of the FAA Act, section 1111(d) of the Homeland Security Act of 2002, and parts 4 and 9 of the TTB regulations, TTB establishes the "Tryon Foothills" AVA in Polk County, North Carolina, effective 30 days from the publication date of this document.
Boundary Description
See the narrative description of the boundary of the Tryon Foothills AVA in the regulatory text published at the end of this final rule.
Maps
The petitioner provided the required maps, and they are listed below in the regulatory text. The Tryon Foothills AVA boundary may also be viewed on the AVA Map Explorer on the TTB website, at https://www.ttb.gov/wine/ava-map-explorer.
Impact on Current Wine Labels
Part 4 of the TTB regulations prohibits any label reference on a wine that indicates or implies an origin other than the wine's true place of origin. For a wine to be labeled with an AVA name or with a brand name that includes an AVA name, at least 85 percent of the wine must be derived from grapes grown within the area represented by that name, and the wine must meet the other conditions listed in 27 CFR 4.25(e)(3). If the wine is not eligible for labeling with an AVA name and that name appears in the brand name, then the label is not in compliance and the bottler must change the brand name and obtain approval of a new label. Similarly, if the AVA name appears in another reference on the label in a misleading manner, the bottler would have to obtain approval of a new label. Different rules apply if a wine has a brand name containing an AVA name that was used as a brand name on a label approved before July 7, 1986. See 27 CFR 4.39(i)(2) for details.
With the establishment of the Tryon Foothills AVA, its name, "Tryon Foothills," will be recognized as a name of viticultural significance under § 4.39(i)(3) of the TTB regulations (27 CFR 4.39(i)(3)). The text of the regulations clarifies this point. Consequently, wine bottlers using the name "Tryon Foothills" in a brand name, including a trademark, or in another label reference as to the origin of the wine, will have to ensure that the product is eligible to use the AVA name as an appellation of origin.
The establishment of the Tryon Foothills AVA will not affect any existing AVA. The establishment of the Tryon Foothills AVA will allow vintners to use "Tryon Foothills" as an appellation of origin for wines made primarily from grapes grown within the Tryon Foothills AVA if the wines meet the eligibility requirements for the appellation.
Regulatory Flexibility Act
TTB certifies that this regulation will not have a significant economic impact on a substantial number of small entities. The regulation imposes no new reporting, recordkeeping, or other administrative requirement. Any benefit derived from the use of an AVA name would be the result of a proprietor's efforts and consumer acceptance of wines from that area. Therefore, no regulatory flexibility analysis is required.
It has been determined that this final rule is not a significant regulatory action as defined by Executive Order 12866, as amended. Therefore, no regulatory assessment is required.
The Regulatory Amendment
For the reasons discussed in the preamble, TTB amends 27 CFR part 9 as follows:
