Hatton Daniels|RosÉ of Dornfelder
Hatton Daniels|Rosé of Dornfelder Mokelumne Glen Vineyard |Mokelumne River AVA The Story: This is a true story of expecting to kiss a frog and finding beautiful wines and great people. Hatton Daniels is a tiny Napa winery working with unusual varietals: Dornfelder, Blaufränkisch, Zweigelt, and Malvasia Bianco, in addition to Pinot Noir and Cabernet Sauvignon. Dan Fishman is the winemaker, who in 2007 worked at Calvert Woodley Fine Wine & Spirits in DC. He makes some of the most interesting California wines we have tasted in a long time. Production ranges from 25-115 cases so there is not much to go around, but they are worth seeking out. Vineyard: Mokelumne Glen Vineyard in Lodi, CA. Viticultural practices include cane pruning (seldom used in the Lodi area) and expanded vertical trellis, and a dual irrigation system utilizing the most favorable benefits of both drip and sprinkler. Grapes harvested prior to full maturity for fresh rose acidity. Vinification: Clusters were pressed directly after harvest, squeezed very gently, only using about 60% of the total potential juice to ensure light color and delicate flavors. The wine was then fermented with native yeast in old oak barrels, and ultimately transferred to a used 500L puncheon for aging. Malolactic fermentation was prevented in order to preserve the beautiful, fresh acidity. Ageing: Aged 3 months in barrel. Everything else you want to know about this wine: The wine was bottled without fining or filtration. For this reason it often throws a sediment, or even so-called “wine-diamonds,” the crystals of tartaric acid that form when the wine is chilled. -

A to Z Glossary of Wine Terms A ABV (Alcohol by Volume) - A measure of the alcohol concentration of a wine, usually expressed as a percentage. Acidic - A tart, sour, or fresh feeling in the mouth when you taste the wine. Aeration - Adding oxygen to the wine to soften tannins. Aggressive – Wine tasting term describing a wine that is either too tannic, too acidic, or a combina- tion of both. Alcohol - Ethanol; in wine it is produced via fermentation with yeast and sugar. Alcoholic – Wine tasting term indicating high alcohol. A wine with a noticeably high alcohol con- tent; perceived as a hotness in the wine. Angular – Wine tasting term used to describe young wines that display predominately sharp, bitter, or tart flavor characteristics. AOC (Appellation d’origine contrôlée) - A term in the French wine designation system which means “controlled designation of origin.” It identifies the location or region where a wine is made. Appearance - In general, the term appearance is used to describe the clarity of a wine. Appellation - A designated wine growing area governed by specific rules regarding the wine grapes grown and wine produced in the specific appellation areas. Aroma - A wine’s scent characteristics; very closely tied in with the flavors. Aromatic - Varieties of grapes that have especially noticeable aromas. Some aromatic grapes in- clude Viognier, Torrontés, Gewürztraminer, Riesling, Muscat, and Pinot Gris. Aromatized – A wine that is infused with botanicals. Vermouth is an aromatized wine.

The Determination of Oxidation Behavior of White Wines Produced from Local and European Grape Varieties Using Spectrophotometric Method
Journal of Engineering Science Vol. XXV, no. 4 (2018), pp. 82 - 93 Fascicle Food engineering ISSN 2587-3474 Topic Biotechnologies, Food Chemistry and Food Safety eISSN 2587-3482 DOI:10.5281/zenodo.2576746 CZU 663.221:634.85(4) THE DETERMINATION OF OXIDATION BEHAVIOR OF WHITE WINES PRODUCED FROM LOCAL AND EUROPEAN GRAPE VARIETIES USING SPECTROPHOTOMETRIC METHOD Iurie Scutaru*, Anatol Balanuta, Dan Zgardan Technical University of Moldova, Department of Oenology, Chisinau, Republic of Moldova *Corresponding author: Iurie Scutaru, [email protected] Received: November, 2, 2018 Accepted: December, 18, 2018 Abstract: The article deals with the oxidation processes of experimental wines produced from indigenous grape varieties Legenda, Viorica and European grapes Chardonnay, Sauvignon. The browning processes in wine are corelated with oxidation of hydroxycinnamates (hydroxycinnamic acids and their tartaric esters, HCAs) ‒ the most important group of phenolic compounds in white wines. The potential degree of wine colour changes has been appreciated using Polyphenols Oxidative Medium test (POM-test). The oxidative crocin bleaching (CBA – Crocin Bleaching Assay) has been studied using the method of competition kinetics. The comparative antioxidant capacity of wines has been determined with peroxy radicals 2,2'-Azobis (2-amidinopropane) dihydrochloride (AAPH). Key words: antioxidant capacity, crocin oxidative bleaching, flavonoids, hydroxycinnamates, phenolic compounds, POM-test, wine oxidation. Introduction The biggest part of Moldovan wines are produced from European grape varieties, that are adapted to local growing conditions. These grape varieties are: Chardonnay, Sauvignon, Cabernet-Sauvignon, Merlot etc. At the same time, recently, in Republic of Moldova, much attention has been given to the goal of using the potential of old local grape varieties (Feteasca Alba, Feteasca Regala, Feteasca Neagra, Rara Neagra) and new grape varieties (Viorica, Legenda, Riton). -
Wine That Stinks As Part of Our Winemaking Coursework at UCC We
Wine that Stinks As part of our winemaking coursework at UCC we study sensory science, the science of how humans perceive smells and tastes with respect to wine. This is one of my favorite classes to teach because it was the interesting smells and tastes in different wines which initially stirred my passion for wine and eventually inspired me to change careers from engineering to winemaking. One of the most interesting parts about teaching the sensory science class is our laboratory session on wine faults. In this lab, perhaps more so than others, the students are very excited to get the opportunity to smell and understand fault aromas, and I’m also excited to show them the stinkiest examples of faulty wine I can find. It seems to be a natural human impulse that when we find something uncharacteristically pungent we want to share it with others: “Wow this is disgusting; you’ve got to smell this!” A couple of recent experiences reminded me of my wine fault lab samples. In the first experience I was at a family reunion when several relatives asked if I’d ever had the wines of a particular Washington winery. One of their high school classmates was married to the winemaker and they were interested in my impression of the wines. I replied that I had only one opportunity to taste the wine of this producer (the price of these wines is usually beyond my budget), but that unfortunately the particular bottle I had tried was “corked,” so I was unable to give them my impression of the wine. -

Wine loss refers to loss occurring when the consumer does not consume the wine contained in the bottle and disposes of it because of taste alteration, which is caused by inadequate product protection rendering the wine unpalatable to a knowledgeable consumer. -
2013 Cambiata Dornfelder, Santa Lucia Highlands
2013 Dornfelder Unconventional and Iconoclastic Cambiata is not your average California winery. We are a little more unconventional and iconoclastic than our compatriots around the Golden State. I launched Cambiata in 2002 after making wines for other people for nearly two decades. My intention was to produce distinctive bottlings that go beyond the Franco triumvirate of Bordeaux, Burgundy and Rhone. Today, we are vinifying a handful of compelling wines from some of California’s scarcest grape varieties including Albariño, Tannat and Dornfelder. We also make limited quantities of Pinot Noir and Chardonnay from the Santa Lucia Highlands. Enjoy. What The Hell? Walk past the rows of meticulously manicured Pinot Noir and Chardonnay to the top of the McIntyre Estate Vineyard and you’ll find a single acre of strange-looking vines bearing long, loose clusters of pitch black berries. “What the hell?” you mumble to the wind. “What vintner would have the cajones to plant Dornfelder in the Santa Lucia Highlands?” Turns out, we would. We figured if the grape loves Germany so much, it should thrive in the cold, windy climate of the Salinas Valley. Kissing Cousins Dornfelder, related by marriage to Pinot Noir, is the second-most planted red grape in Germany. When grown in the right location and made with labor-intensive, artisan practices, it can produce a rich, age worthy, red wine that offers incredibly juicy aromatics and luscious flavors. Just like our Pinot Noir, the wine was fermented in open top fermenters with frequent punch downs of the cap. It spent approximately 14 months in 100% French oak barrels (40% new) prior to bottling. -

Dornfelder Rheinhessen 2011
ESTATE DORNFELDER RHEINHESSEN 2011 Albrecht Schneider’s maxim has always been absolute devotion to his vineyards and wines, whilst marketing was considered less important. He had to take over the “reigns” at an early age in 1967 after his apprenticeship at the Langwerth von Simmern estate, and even in those early days, he realized that only healthy soils could allow the cultivation of fine wines, and began with interrow crops while modernizing from horse to special light trac- tor. The estate has been owned by the Schneider family for 7 generations, and today at vintage time, three gen- erations are at work.

Analysis of Vocs in Wine by Purge & Trap Concentrations and GC/MS
Analysis of Volatile Organic Compounds in Wine by Purge and Trap Concentration and Gas Chromatography/ Mass Spectrometry (GC/MS) Introduction Many of the flavors and fragrances which make up a wine’s profile consist of volatile organic compounds (VOCs). These chemicals, even at small concentrations can affect the flavor and aroma of a wine. Many subjective descriptors are used such as buttery, a hint of oak, peppery, vanilla, and so on. Wine flavors and aromas can be organized into three primary groups: fruit; floral; and herbal, spice, and earth.1 VOCs are produced at different times in the winemaking process. For instance, VOCs accumulate in the grape as the grape seed matures and as the fruit ripens by binding to other molecules such as sugars and amino acids. Winemakers release these compounds by breaking Eclipse 4760 P&T and 4100 Autosampler the bonds: both physically by crushing the grapes and chemically during fermentation with grape and yeast enzymes.2 Traditionally, the detection of VOCs has been accomplished by the oenologist through taste and smell. There is growing interest in using chemical analysis to identify and quantitate the VOCs in the various stages of the winemaking process. For example, esters can add fruit and flower notes; terpenes can add piney, rose, and lavender notes; and organic acids can add sour, vinegary notes.1 The use of GC/MS may lead to identification of previously unknown VOCs in wine as well as help winemakers make adjustments to the growing and winemaking techniques based upon scientific data. Many VOCs can be analyzed by purge and trap concentration and detection by GC/MS.
