9.5 New York State & the Eastern United States
Key Takeaways
- New York is in the northeastern United States with a continental climate moderated by deep lakes and rivers inland and by the Atlantic Ocean on the coast.
- The Certified level adds three AVAs to the Introductory-level Finger Lakes AVA: Hudson River Region AVA, Lake Erie AVA and Long Island AVA.
- Growers must protect vines from deep winter freezes and from summer mould, which is why hybrids and native species remain commercially important.
- Certified candidates must know hybrids Aurore and Seyval Blanc, and the Vitis labrusca variety Concord, alongside vinifera Riesling, Gewürztraminer, Chardonnay, Pinot Noir, Merlot and Cabernet Franc.
- Dr. Konstantin Frank is the historical figure CMS-A names, credited with proving Vitis vinifera could survive Finger Lakes winters.
New York State & the Eastern United States
American wine study tends to collapse into California, with a nod to Oregon and Washington. The CMS-A curriculum does not allow that shortcut: New York State is its own subject with its own Certified-level learning outcome.
A candidate will know the major AVAs and grape varieties grown in New York State (including hybrids and other species). Certified Sommeliers will be able to recommend and sell food pairings with New York wines to a guest.
That parenthesis is the point of the whole subject. New York is the region where CMS-A tests whether a candidate understands that the wine world is not exclusively Vitis vinifera.
1. Climate, Geography & the Moderator Problem
| Feature | Detail |
|---|---|
| Location | Northeastern United States |
| Climate | Continental, with moderating influences from lakes and rivers inland and from the Atlantic Ocean on the coast |
| Finger Lakes physical feature | Deep glacial lakes |
| Grape growing challenge | Must protect vines from deep freezes during harsh winters and from mould in the summer |
The Finger Lakes are long, narrow, and — critically — deep, gouged by Pleistocene glaciers. Deep water holds summer heat well into autumn and releases it slowly through winter, so vineyards planted on the slopes immediately above the lakes sit in a thermal buffer that can be several degrees warmer than land a short distance away. Without that buffer, commercial viticulture at this latitude would be impossible.
The two hazards are seasonal opposites and they pull grape selection in the same direction:
- Winter — temperatures can fall far enough to kill vinifera buds and even split trunks. Vines may be hilled up with soil; multiple trunks are trained as insurance.
- Summer — humidity brings downy and powdery mildew, black rot and botrytis bunch rot. Canopy management and disease-resistant genetics both matter.
2. The Four Examinable AVAs
CMS-A places Finger Lakes AVA at the Introductory level and adds three more at the Certified level.
| AVA | Level | Location & character |
|---|---|---|
| Finger Lakes AVA | Introductory | Deep glacial lakes in west-central New York; the state's quality benchmark, above all for Riesling |
| Hudson River Region AVA | Certified | The Hudson River valley north of New York City; one of the oldest continuously cultivated wine regions in the United States |
| Lake Erie AVA | Certified | The lakeshore strip in the state's far west, shared with Pennsylvania and Ohio; dominated by Concord for juice and jelly as well as wine |
| Long Island AVA | Certified | Maritime, Atlantic-moderated island east of New York City; the state's warmest and longest growing season, with sub-appellations on the North Fork and The Hamptons |
The contrast between Finger Lakes and Long Island is the most useful thing to hold in mind, because it is the same contrast the tasting grid asks about — continental versus maritime.

3. Grape Varieties: Three Genetic Categories
This is the section's examinable core. CMS-A separates New York's plantings into three groups.
| Category | Varieties named by CMS-A | Level |
|---|---|---|
| Vitis vinifera — white | Riesling, Gewürztraminer, Chardonnay | Introductory |
| Vitis vinifera — red | Pinot Noir, Merlot, Cabernet Franc | Introductory |
| Hybrids | Aurore, Seyval Blanc | Certified |
| Vitis labrusca | Concord | Certified |
What the categories actually mean
- Vitis vinifera is the Eurasian species behind essentially every classic wine grape. It makes the finest wine and has the least cold hardiness and disease resistance.
- A hybrid is a cross between vinifera and one or more American species (typically labrusca, riparia or rupestris). Hybrids such as Seyval Blanc and Aurore were bred in France and imported to survive continental winters and humid summers. Note the vocabulary trap: a crossing is a cross of two varieties within the same species (Müller-Thurgau, Pinotage), whereas a hybrid crosses different species.
- Vitis labrusca is a native North American species. Concord is its emblem — deeply coloured, intensely aromatic, and carrying the distinctive "foxy" aroma produced by the compound methyl anthranilate. It is the flavour of American grape juice and jelly, and it is unmistakable in a glass.
[!TIP] If a theory question asks for an example of Vitis labrusca, the answer is Concord (CMS-A also names Catawba in the viticulture chapter). If it asks for a hybrid grown in New York, the answer is Seyval Blanc or Aurore. If it asks for the hybrid used for Canadian icewine, the answer is Vidal — a different hybrid for a different country, and a classic distractor pairing.
4. Dr. Konstantin Frank
CMS-A lists exactly one name under History & Lore for New York: Dr. Konstantin Frank.
A Ukrainian-born plant scientist who arrived in the United States in 1951, Frank argued against the prevailing orthodoxy that Vitis vinifera could not survive Finger Lakes winters. His insight was that the problem was not the species but the rootstock: grafted onto sufficiently cold-hardy roots, and drawing on his experience with viticulture in cold continental Ukraine, vinifera could indeed ripen and survive. Working first at the Geneva experiment station and then with Gold Seal Vineyards, he proved it, and founded Dr. Konstantin Frank Vinifera Wine Cellars in 1962.
Every bottle of Finger Lakes Riesling descends from that argument, which is why his is the one name the curriculum requires.
