Establishment of the Contra Costa Viticultural Area and
Modification of the San Francisco Bay and Central Coast Viticultural
Areas
AGENCY: Alcohol and Tobacco Tax and Trade Bureau, Treasury.
ACTION: Final rule; Treasury decision.
-----------------------------------------------------------------------
SUMMARY: The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes
the approximately 167,146-acre ``Contra Costa'' American viticultural
area in Contra Costa County, California. Additionally, TTB is expanding
the boundaries of the established San Francisco Bay and Central Coast
viticultural areas to avoid a partial overlap with the Contra Costa
viticultural area and instead encompass the entire Contra Costa AVA.
TTB designates viticultural areas to allow vintners to better describe
the origin of their wines and to allow consumers to better identify
wines they may purchase.
DATES: This final rule is effective April 15, 2024.

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 (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 administration 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
[[Page 18798]]
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:
Evidence that the area within the proposed AVA boundary is
nationally or locally known by the AVA name specified in the petition;
An explanation of the basis for defining the boundary of
the proposed AVA;
A narrative description of the features of the proposed
AVA affecting viticulture, such as climate, geology, soils, physical
features, and elevation, that make the proposed AVA distinctive and
distinguish it from adjacent areas outside the proposed AVA;
If the proposed AVA is to be established within, or
overlapping, an existing AVA, an explanation that both identifies the
attributes of the proposed AVA that are consistent with the existing
AVA and explains how the proposed AVA is sufficiently distinct from the
existing AVA and therefore appropriate for separate recognition;
The appropriate United States Geological Survey (USGS)
map(s) showing the location of the proposed AVA, with the boundary of
the proposed AVA clearly drawn thereon; and
A detailed narrative description of the proposed AVA
boundary based on USGS map markings.
Petition To Establish the Contra Costa AVA and To Expand the Boundaries
of the San Francisco Bay and Central Coast AVAs
TTB received a petition on behalf of the Contra Costa Winegrowers
Association proposing to establish the ``Contra Costa'' AVA and expand
the boundaries of the established San Francisco Bay (27 CFR 9.157) and
Central Coast (27 CFR 9.75) AVAs. The proposed Contra Costa AVA is
within Contra Costa County, California. The proposed AVA covers
approximately 167,146 acres and currently contains at least 60
commercial vineyards covering a total of approximately 1,700 acres, as
well as at least 14 wineries. According to the petition, the
distinguishing features of the proposed AVA are its topography and
climate.
The proposed Contra Costa AVA consists of relatively flat terrain
interrupted in places by rolling hills. All elevations within the
proposed AVA are below 1,000 feet, and most elevations are below 100
feet. Over 71 percent of the slope angles within the proposed AVA are
less than 5 percent, but along the western and southern boundary and in
the ridgeline that runs north-south between Concord and Bay Point,
slope angles can reach 30 percent. The petition states that cool, heavy
marine air stays at lower elevations, leading to diurnal cooling that
can cause differences in grape development, the timing of harvest, and
sugar accumulation and acidity in the grapes when compared to the same
varietals grown at higher elevations.
East of the proposed AVA, the terrain is generally flat as one
moves into the California Delta and the San Joaquin Valley. To the
south and west of the proposed AVA, the terrain becomes steeper, with
slope angles generally exceeding 20 percent and commonly above 30
percent. Elevations to the west and south of the proposed AVA are also
generally higher than within the proposed AVA, exceeding 1,300 feet in
the region to the west and reaching 3,849 feet at the summit of Mt.
Diablo to the south of the proposed AVA.
The petition also includes climate data in the form of growing
degree day (GDD) accumulations \1\ and average annual precipitation
amounts. Within the proposed Contra Costa AVA, annual GDD accumulations
between 2014 and 2019 ranged from 3,008 to 4,275, indicating a
generally warm climate. The petition states that the proposed AVA's
climate is suitable for growing a variety of grapes, including
Zinfandel, petite sirah, mourvedre, chardonnay, and cabernet sauvignon.
---------------------------------------------------------------------------
\1\ See Albert J. Winkler et al., General Viticulture (Berkeley:
University of California Press), pp. 61-64 (1974). In the Winkler
climate classification system, annual heat accumulation during the
growing season, measured in annual GDDs, defines climatic regions.
One GDD accumulates for each degree Fahrenheit that a day's mean
temperature is above 50 degrees F, the minimum temperature required
for grapevine growth.
---------------------------------------------------------------------------
To the northeast of the proposed AVA, at Jersey Island, GDD
accumulations from 2014 to 2019 were similar to those found in the
proposed AVA, but the petitioner chose to exclude this region from the
proposed AVA because of its mucky soils that are unlikely to support
viticulture. To the south, in Walnut Creek, GDD accumulations were also
similar to those within the proposed AVA, although the petitioner
excluded this region from the proposed AVA because it is a largely
residential area that is not suited for commercial viticulture. Farther
south, in Byron, GDD accumulations were significantly higher than those
within the proposed AVA. To the east, within the San Joaquin Valley,
GDD accumulations were generally warmer than within the proposed AVA,
as the marine influence decreases as one moves farther inland. West of
the proposed AVA, as one moves closer to San Francisco Bay and the
Pacific Ocean, GDD accumulations were lower than within the proposed
AVA.
Within the proposed Contra Costa AVA, annual precipitation amounts
from 2013 to 2018 ranged from a low of 232 millimeters (mm) to a high
of 565 mm. During the same time period, annual precipitation amounts to
the west and southwest of the proposed AVA were generally higher,
ranging from a low of 374 mm to a high of 1,712 mm. Although the
petition included precipitation data for regions to the northeast,
east, and southeast of the proposed AVA, TTB excluded the data from the
proposed rule document because the data was collected from a period of
two years or less and therefore TTB was unable to determine whether
precipitation was a distinguishing feature of the proposed AVA in
relation to those regions.
Modification of the San Francisco Bay AVA Boundary
The San Francisco Bay AVA was established by T.D. ATF-407 on
January 20, 1999 (64 FR 3015). T.D. ATF-407 describes the
distinguishing feature of the San Francisco Bay AVA as ``a marine
climate which is heavily influenced by the proximity of the San
Francisco Bay and the Pacific Ocean.'' T.D. ATF-407 also notes that the
eastern boundary of the AVA was chosen, in part, as a way of separating
the AVA from the drier, warmer inland region of the Central Valley,
which lacks a strong marine influence. Only the western portion of the
proposed Contra Costa AVA lies within the existing San Francisco Bay
AVA. To eliminate the partial overlap, the petitioner also proposed
expanding the boundary of the San Francisco Bay AVA to encompass the
entire Contra Costa AVA. The proposed expansion would increase the size
of the San Francisco Bay AVA by approximately 109,955 acres. The
proposed Contra Costa AVA shares some of the characteristics of the
larger established AVA. For example, similar to other locations in the
San Francisco Bay AVA, information provided in the petition to
establish the Contra Costa AVA showed that the proposed AVA is
[[Page 18799]]
affected by cool, moist air from the Pacific Ocean and the San
Francisco Bay. The proposed AVA is also generally cooler and wetter
than the inland region to the east. However, the proposed Contra Costa
AVA has some characteristics that distinguish it from the larger San
Francisco Bay AVA. For instance, although the proposed Contra Costa AVA
is influenced by marine air from the San Francisco Bay, the proposed
AVA is not adjacent to San Francisco Bay, the air travelling through
Suisun Bay instead. Additionally, while T.D. ATF-407 describes the San
Francisco Bay AVA as having a cool Mediterranean climate
classification, the proposed Contra Costa AVA also includes regions
with a warm Mediterranean climate classification.
Modification of the Central Coast AVA Boundary
The petition also proposes to expand the boundary of the
established Central Coast AVA. The Central Coast AVA was established by
T.D. ATF-216 on October 24, 1985 (50 FR 43128). T.D. ATF-216 describes
the Central Coast AVA as a region between the Pacific Ocean and the
Coast Ranges of California. The Central Coast AVA has a climate that is
greatly affected by the marine influence, with the region to the east
of the AVA having a more arid climate.
Only the western portion of the proposed Contra Costa AVA lies
within the existing Central Coast AVA. To eliminate the partial
overlap, the petitioner also proposed modifying the boundary of the
Central Coast AVA to encompass the entire Contra Costa AVA. The
proposed modification would increase the size of the Central Coast AVA
by approximately 109,955 acres. Information provided in the petition to
establish the Contra Costa AVA showed that the proposed Contra Costa
AVA shares some of the characteristics of the larger established AVA.
For example, similar to other locations in the Central Coast AVA, the
proposed AVA is affected by cool, moist air from the Pacific Ocean,
which enters the region from San Francisco Bay via Suisun Bay. The
proposed AVA is also generally cooler and wetter than the region to the
east. However, the proposed Contra Costa AVA has some characteristics
that distinguish it from the larger Central Coast AVA. For instance,
being a smaller region, the proposed AVA has less topographic variety
than the Central Coast AVA. Additionally, being adjacent to the
shoreline of Suisun Bay, the proposed AVA is more directly exposed to
cool marine air than other regions of the Central Coast AVA, such as
the Paso Robles AVA (27 CFR 9.84), which is farther inland and,
according to T.D. ATF-216, receives its marine air via the Salinas
River, which empties into Monterey Bay.
Notice of Proposed Rulemaking and Comments Received
TTB published Notice No. 223 in the Federal Register on March 29,
2023 (88 FR 18471), proposing to establish the Contra Costa AVA and
expand the boundaries of the San Francisco Bay and Central Coast AVAs.
In the notice, TTB summarized the evidence from the petition regarding
the name, boundary, and distinguishing features for the proposed
viticultural area. The notice also compared the distinguishing features
of the proposed viticultural area to the surrounding areas. For a
description of the evidence relating to the name, boundary, and
distinguishing features of the proposed viticultural area, and for a
comparison of the distinguishing features of the proposed viticultural
area to the surrounding areas, see Notice No. 223.
In Notice No. 223, TTB solicited comments on the accuracy of the
name, boundary, distinguishing features, and other required information
submitted in support of the petition. In addition, TTB solicited
comments on the proposed modifications of the established Central Coast
and San Francisco Bay AVAs and whether the evidence presented in the
proposed Contra Costa AVA petition sufficiently supported the
modifications. The comment period for Notice No. 223 closed on May 30,
2023. In response to Notice No. 223, TTB received seven comments.
Commenters include local wine industry members, the Contra Costa
Winegrowers Association, the Downtown Brentwood Coalition, the mayor of
the city of Brentwood, and the original petitioner. All seven comments
support the establishment of the proposed Contra Costa AVA. None of the
comments specifically addressed the proposed expansion of the San
Francisco Bay or Central Coast AVAs.
Additionally, the comment from the petitioner (comment 1) clarified
that Viano Vineyards is within both the proposed Contra Costa AVA and
the unmodified Central Coast AVA. The petitioner states that TTB's
description of Viano Vineyards on page 18476 of the proposed rule
document made it seem as if the vineyard was not within the unmodified
boundary of the Central Coast AVA. TTB agrees with the commenter that
Viano Vineyards is within both the proposed Contra Costa AVA and the
unmodified Central Coast AVA boundary. Comment 2 also noted that the
second page of Exhibit I to the petition, which is marked as a list of
members of the Contra Costa Winegrowers Association, includes persons
who are members of the Lamorinda AVA association, not the Contra Costa
Winegrowers Association. Exhibit I is not a TTB document, but TTB notes
that winegrowers associations may accept members from neighboring
regions outside of the particular AVA, and that members listed in the
exhibit may be members of both associations. Because TTB did not
receive any additional clarification from the petitioner regarding this
exhibit, TTB is not amending the exhibit in the docket.
TTB Determination
After careful review of the petition and of the comments received
in response to Notice No. 223, TTB finds that the evidence provided by
the petitioner supports the establishment of the approximately 167,146-
acre Contra Costa AVA and the expansion of the boundaries of the San
Francisco Bay and Central Coast AVAs. 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 ``Contra
Costa'' AVA in Contra Costa County, California.
Furthermore, TTB expands the boundaries of the San Francisco Bay
and Central Coast AVAs to entirely encompass the Contra Costa AVA,
after finding that the evidence provided by the petitioner shows that
the features of the expansion areas described in Notice No. 223 are
consistent with the features of the established AVAs. These changes are
effective April 15, 2024.
Boundary Description
See the narrative boundary description of the Contra Costa AVA and
the expanded boundaries of the San Francisco Bay and Central Coast AVAs
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 Contra Costa AVA boundary and the
expanded San Francisco Bay and Central Coast AVA boundaries 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
[[Page 18800]]
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 Contra Costa AVA, its name, ``Contra
Costa,'' will be recognized as a name of viticultural significance
under Sec. 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 ``Contra Costa'' in a brand name, including a
trademark, or in another label reference 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 AVA will not affect
the use of ``Contra Costa County'' as a county appellation of origin on
wine labels.
The establishment of the Contra Costa AVA will allow vintners to
use ``Contra Costa'' as an AVA appellation of origin for wines made
primarily from grapes grown within the Contra Costa AVA if the wines
meet the eligibility requirements for the appellation. The expansion of
the Central Coast and San Francisco Bay AVAs will also allow vintners
to use ``Central Coast,'' ``San Francisco Bay,'' or both, as
appellations of origin for wines made primarily from grapes grown
anywhere in the Contra Costa AVA if the wines meet the eligibility
requirements for the appellation.
Bottlers who wish to label their wines with ``Contra Costa'' as an
AVA appellation of origin must obtain a new Certificate of Label
Approval (COLA) for the label, even if the currently approved label
already contains another AVA appellation of origin. Please do not
submit COLA requests to TTB before the effective date shown in the
Dates section of this document, or your request will be rejected.
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.
Executive Order 12866
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.

4. Add Sec. 9.291 to read as follows:
Sec. 9.291 Contra Costa.
(a) Name. The name of the viticultural area described in this
