Ashes in the Glass: Smoke Taint and the New Reality of Wine

Burgundy Explained: Pinot Noir, Chardonnay, and the Power of Place

Send me your thoughts at ibotezatu5@gmail.com [https://www.buzzsprout.com/2519422/fan_mail/new] In this episode of The Wine Lab, we continue our series on the great wine regions of the world with Burgundy, or Bourgogne, one of France’s most influential and fascinating wine regions. Burgundy is famous for Pinot Noir and Chardonnay, but its true identity is built around place: villages, vineyards, slopes, soils, and precisely delimited parcels known as Climats. This episode explains the major Burgundy regions, from Chablis and the Côte d’Or to the Côte Chalonnaise and the Mâconnais, while exploring how Burgundy’s appellation hierarchy, monastic history, grape varieties, and wine styles shaped its global reputation. We also compare Burgundy and Bordeaux as color names and as wine cultures, discuss the role of Pinot Noir and Chardonnay, explain terms such as Premier Cru and Grand Cru, and consider how climate change is affecting one of the world’s most place-sensitive wine regions. Glossary Bourgogne The French name for Burgundy. You will often see “Bourgogne” on wine labels instead of “Burgundy.” Burgundy A historic wine region in eastern France, best known for Pinot Noir-based red wines and Chardonnay-based white wines. Bordeaux A major wine region in southwestern France, often associated with blends based on Cabernet Sauvignon, Merlot, Cabernet Franc, and related varieties. Also used as a color name for a deep wine-red shade. Climat In Burgundy, a precisely delimited vineyard parcel with its own identity, shaped by soil, slope, exposure, history, and human cultivation. Terroir The combined influence of place on wine, including soil, climate, topography, vine material, farming, and human decision-making. Pinot Noir Burgundy’s main red grape variety. It is thin-skinned and often produces wines with red fruit, floral, earthy, and spice notes. Chardonnay Burgundy’s main white grape variety. It can produce wines ranging from crisp, citrusy, and mineral to broad, creamy, and layered. Aligoté A traditional white grape of Burgundy, often producing crisp, fresh, high-acid wines. It has been receiving renewed attention from producers and consumers. Gamay A red grape associated most strongly with Beaujolais, but also present in some Burgundy-related appellations and blends. Chablis A northern Burgundy wine area known for Chardonnay wines with bright acidity, citrus character, and often mineral or saline impressions. Côte d’Or The central and most famous part of Burgundy, divided into the Côte de Nuits and Côte de Beaune. Côte de Nuits The northern part of the Côte d’Or, especially famous for Pinot Noir-based red wines. Côte de Beaune The southern part of the Côte d’Or, known for both Pinot Noir and some of the world’s most famous Chardonnay-based white wines. Côte Chalonnaise A Burgundy subregion south of the Côte d’Or, producing Pinot Noir, Chardonnay, Aligoté, and sparkling wines, often with strong value. Mâconnais A southern Burgundy subregion especially known for Chardonnay-based white wines, including wines from Pouilly-Fuissé, Saint-Véran, and Mâcon-Villages. Regional appellation A broad Burgundy appellation category, such as Bourgogne Rouge or Bourgogne Chardonnay. These wines usually come from wider geographic areas. Village appellation An appellation named after a specific commune or village, such as Meursault, Pommard, or Nuits-Saint-Georges. Premier Cru A classification for recognized high-quality vineyard sites within a village appellation. Grand Cru The highest vineyard classification in Burgundy. Grand Cru wines come from the most prestigious vineyard sites, where the vineyard name itself is the appellation. Crémant de Bourgogne Traditional-method sparkling wine from Burgundy, made from approved regional grape varieties such as Chardonnay, Pinot Noir, Aligoté, and Gamay. Whole-cluster fermentation A red winemaking technique in which some or all grape clusters are fermented with stems included. It can influence aroma, tannin, structure, and spice character. Bâtonnage The stirring of lees during wine aging, often used in white winemaking to influence texture, mouthfeel, and aromatic complexity. Malolactic fermentation A microbial conversion of malic acid into lactic acid. In white Burgundy, it can contribute to a softer texture and buttery or creamy impressions, depending on style and conditions.

Bordeaux Wines Beyond the Château: Grapes, Climate, and Blending

Send me your thoughts at ibotezatu5@gmail.com [https://www.buzzsprout.com/2519422/fan_mail/new] Bordeaux is one of the most influential wine regions in the world, but it can also feel intimidating. In this episode of The Wine Lab, Andreea  explains Bordeaux through the features that define it: rivers, climate, soils, grape varieties, blending, classifications, aging, and wine style. The episode covers the differences between the Left Bank and Right Bank, the roles of Cabernet Sauvignon, Merlot, Cabernet Franc, Sauvignon Blanc, Sémillon, and other Bordeaux varieties, and why blending became both a sensory and practical strategy in this maritime region. It also introduces Bordeaux’s dry white wines, the noble rot wines of Sauternes and Barsac, food pairing ideas, serving temperature, decanting, vintage variation, and the impact of climate change. The episode also discusses Bordeaux’s approval of new climate-adaptation varieties, including Arinarnoa, Castets, Marselan, Touriga Nacional, Alvarinho, and Liliorila, and what this reveals about tradition, resilience, and the future of classic wine regions. Glossary Bordeaux: A major wine region in southwest France, known especially for red blends based on Merlot, Cabernet Sauvignon, and Cabernet Franc, as well as dry white and sweet wines. Left Bank: The area west and south of the Gironde Estuary and Garonne River, often associated with Cabernet Sauvignon-dominant red blends and gravelly soils. Right Bank: The area north and east of the Dordogne River, often associated with Merlot-dominant red blends and clay-limestone soils. Entre-Deux-Mers: A Bordeaux area between the Garonne and Dordogne rivers. The name means “between two seas.” Maritime climate: A climate influenced by proximity to the ocean, usually with moderated temperatures and relatively high humidity. Bordeaux blend: A wine blend based on traditional Bordeaux grape varieties, commonly Merlot, Cabernet Sauvignon, Cabernet Franc, Petit Verdot, Malbec, and sometimes Carménère for reds. Cabernet Sauvignon: A late-ripening red grape associated with blackcurrant, cassis, firm tannins, cedar, graphite, and aging potential. Merlot: A red grape associated with plum, black cherry, roundness, softer tannins, and a plush mouthfeel. Cabernet Franc: A red grape often used in Bordeaux blends for aromatic lift, freshness, red fruit, floral notes, and spice. Petit Verdot: A red grape used in smaller proportions in Bordeaux blends, often contributing color, tannin, and spice. Carménère: A historic Bordeaux red grape that is now more strongly associated with Chile. Sauvignon Blanc: A white grape that contributes citrus, grapefruit, herbal notes, and bright acidity to dry white Bordeaux. Sémillon: A white grape that contributes body, texture, beeswax, lemon curd, and aging potential; also central to Sauternes and Barsac. Muscadelle: An aromatic white grape used in smaller proportions in some Bordeaux white and sweet wines. 1855 Classification: A historic Bordeaux classification created for the 1855 Paris Exposition, ranking red wines from the Médoc and Château Haut-Brion from Graves, as well as sweet wines from Sauternes and Barsac. First Growth / Premier Cru Classé: The highest tier in the 1855 classification for red Bordeaux wines. Cru Bourgeois: A quality designation mainly associated with Médoc estates outside the 1855 classified growths. Pessac-Léognan: A Bordeaux appellation known for both red wines and high-quality dry white wines. Sauternes and Barsac: Bordeaux appellations known for sweet wines made from grapes affected by noble rot. Botrytis cinerea / Noble rot: A fungus that, under the right conditions, dehydrates grapes and concentrates sugars, acids, and flavor compounds, producing complex sweet wines. Tannin: Phenolic compounds from skins, seeds, and oak that create bitterness, astringency, and drying sensations in wine. Polymerization: A process where smaller tannin molecules form larger structures over time, often changing how tannins are perceived in aged wine. Decanting: Pouring wine into another vessel to separate sediment and/or expose the wine to oxygen before serving. Vintage variation: Differences among wines caused by the weather and growing conditions of a specific year. Climate-adaptation varieties: Grape varieties approved or studied to help wine regions adapt to warmer temperatures, drought stress, and other climate-related challenges.

Grip, Weight, and Freshness: Understanding Wine Mouthfeel

Send me your thoughts at ibotezatu5@gmail.com [https://www.buzzsprout.com/2519422/fan_mail/new] Wine is usually described through aroma and flavor, but some of its most important qualities are physical. This episode of The Wine Lab examines wine texture and mouthfeel: body, viscosity, acidity, tannin, astringency, alcohol warmth, residual sugar, carbon dioxide, lees aging, malolactic fermentation, serving temperature, and aeration. Andreea explains why two wines with similar flavors can feel completely different, how winemaking choices shape texture, and why service conditions such as temperature and decanting can change the way a wine is perceived. From crisp whites to structured reds and sparkling wines, this episode offers a practical and scientific guide to what the palate feels. Glossary Mouthfeel The tactile sensations a wine creates in the mouth, including body, heat, grip, smoothness, roughness, creaminess, and astringency. Texture The overall physical impression of a wine on the palate. Texture includes how heavy, sharp, soft, drying, prickly, or smooth the wine feels. Body The perceived weight or fullness of a wine in the mouth. Body is influenced by alcohol, sugar, acidity, extract, flavor intensity, and other wine components. Viscosity A liquid’s resistance to flow. In wine, viscosity can contribute to impressions of body or richness, although it is only one part of mouthfeel. Ethanol The main alcohol in wine. Ethanol contributes to body, warmth, aroma release, and the perception of fullness. Glycerol A fermentation byproduct that can contribute slightly to viscosity, though its sensory impact at typical wine concentrations is often smaller than commonly assumed. Acidity The sourness and freshness in wine, mainly shaped by organic acids such as tartaric, malic, and lactic acid. Acidity also influences the physical impression of sharpness, brightness, and refreshment. pH A measure of how acidic or basic a solution is. In wine, pH influences microbial stability, color, sulfur dioxide effectiveness, and sensory perception. Phenolic compounds A broad group of grape- and oak-derived compounds that includes tannins, color pigments, and some compounds linked to bitterness, flavor, and structure. Tannins Phenolic compounds from grape skins, seeds, stems, and oak. Tannins contribute bitterness, structure, and especially astringency in wine. Astringency The drying, puckering, rough, or grippy tactile sensation caused largely by tannins interacting with saliva and oral surfaces. Bitterness A taste sensation detected by taste receptors. Bitterness can occur alongside astringency, but the two are not the same. Maceration The period when grape juice or wine remains in contact with grape skins, seeds, and sometimes stems. Maceration affects color, flavor, tannin, and texture. Mannoproteins Polysaccharides released from yeast cell walls during fermentation and lees aging. They can contribute to roundness, softness, and stability in some wines. Lees Spent yeast cells and other particles that settle after fermentation. Aging wine on lees can influence aroma, texture, and stability. Malolactic fermentation A microbial conversion of malic acid into lactic acid, usually carried out by lactic acid bacteria. It can soften acidity and contribute to a rounder mouthfeel. Diacetyl A compound associated with buttery aromas in wine. It can be produced during malolactic fermenta Support the show [https://www.buzzsprout.com/2519422/support] For more detailed wine science checkout my YouTube channel here: https://www.youtube.com/@Enology_channel

A Rosé by Any Other Name Would Taste as Sweet...or Dry

Send me your thoughts at ibotezatu5@gmail.com [https://www.buzzsprout.com/2519422/fan_mail/new] A glass of rosé often feels effortless - light catching a pale pink hue, a hint of summer in the air - but its story runs deeper. In this episode, we trace how rosé is shaped, from fleeting skin contact to the saignée method and the precise art of blending in sparkling wines. Along the way, we place rosé within a longer human narrative, from early winemaking to Mediterranean tables where it accompanies food, heat, and conversation. What emerges is a style that carries both intention and ease - one that moves gracefully between technique and pleasure, and reveals more the closer you pay attention. Glossary: * Anthocyanins: Pigments in grape skins responsible for red and pink color in wine * Skin contact (maceration): Time during which grape juice remains in contact with skins, extracting color and compounds * Saignée: Method where juice is removed early from a red wine fermentation to produce rosé * Blending: Mixing red and white wines to create rosé (common in sparkling wine production) * Terroir: The combined effect of soil, climate, and environment on wine characteristics Famous Rosé Examples: * Provence Rosé (France): Typically pale, dry, and driven by Grenache and Cinsault; known for freshness and elegance * Tavel (Rhône Valley, France): A deeper-colored, more structured rosé with notable body and aging potential * Bandol Rosé (France): Often Mourvèdre-based, with more weight, spice, and complexity * Rosé Champagne (France): Produced by blending or short maceration; combines freshness with autolytic complexity * White Zinfandel (USA): A sweeter, fruit-forward rosé style that played a major role in popularizing pink wines in the U.S. Support the show [https://www.buzzsprout.com/2519422/support] For more detailed wine science checkout my YouTube channel here: https://www.youtube.com/@Enology_channel

Wait, Wine Isn’t Always Vegan?

Send me your thoughts at ibotezatu5@gmail.com [https://www.buzzsprout.com/2519422/fan_mail/new] Episode description Wine seems like one of the most plant-based products imaginable, so why are some wines not considered vegan? In this episode of The Wine Lab, we look at the cellar practices behind that question. From egg whites, milk proteins, gelatin, and isinglass to bentonite, PVPP, and plant-based alternatives, this is a closer look at fining, clarification, labeling, and the ethics of process. Along the way, the episode traces the long history of these practices in winemaking and considers why vegan wine has become an important question for modern consumers. If you have ever wondered how a wine made from grapes can still raise vegan concerns, this episode offers the science, the history, and the consumer perspective. Glossary Vegan wine: Wine made without the use of animal-derived processing aids or additives. Fining: A winemaking step in which a substance is added to bind unwanted particles or compounds so they can be removed. Fining agent: The material used during fining to clarify or refine the wine. Isinglass: A fining agent derived from fish collagen, traditionally used for clarification. Egg white fining: The use of egg albumen, especially in red wines, to help soften tannins and clarify the wine. Casein: A milk protein used in some wines for clarification and correction of certain defects. Gelatin: An animal-derived protein used as a fining agent. Bentonite: A clay-based fining agent commonly used as a vegan-friendly alternative. PVPP: A synthetic fining material used to remove certain phenolic compounds and help stabilize wine. Processing aid: A material used during production that is not intended to remain in the final product. Clarification: The process of making wine clearer by removing suspended particles. Certification mark: A label or symbol indicating that a product has been verified against a particular standard, such as vegan certification.
