Investigating Quality Attributes And Wine Production Methods Of Arkansas-Grown Grapes, Amanda Fleming
Investigating Quality Attributes And Wine Production Methods Of Arkansas-Grown Grapes, Amanda Fleming
Graduate Theses and Dissertations
Grapevines (Vitis species) are grown worldwide to produce table grapes, juice grapes, dried grapes, and wine with the United States as one of the world’s largest wine and grape producers. Though not a large contributor to the U.S. grape and wine industry, Arkansas’ industry plays an important role in the state’s agritourism and economy. Most grapes grown in Arkansas’ warm climate include native species, such as muscadines (V. rotundifolia) and hybrids (crosses of Vitis species). Two important hybrid red wine grapes grown in Arkansas are Chambourcin, grown commercially for its positive viticulture and enological quality, and Enchantment, a newer cultivar …
Cofermentation, Post-Alcoholic, And Post-Malolactic Fermentation Blending Of Malbec, Merlot And Petite Sirah Wines, Armando Arturo Vega-Osorno
Cofermentation, Post-Alcoholic, And Post-Malolactic Fermentation Blending Of Malbec, Merlot And Petite Sirah Wines, Armando Arturo Vega-Osorno
Master's Theses
A two-year study was conducted to assess the effects of cofermentation on red wine varietals. During the winemaking process, wines can be made from two or more varieties by picking, crushing and fermenting them together, a practice known as cofermentation. They can also be blended either after the completion of alcoholic fermentation or after malolactic fermentation. In the first year of the study, two grape varieties, Merlot (Mer), and Malbec (Mal) were cofermented. On the second year, a third varietal, Petite Sirah (PS) was also studied. Cofermented wines containing every possible binomial combination of the varietals was made and one …
Evaluating Flavor And Aroma Attributes Of Arkansas-Grown Horticultural Crops, Jordan Chenier
Evaluating Flavor And Aroma Attributes Of Arkansas-Grown Horticultural Crops, Jordan Chenier
Graduate Theses and Dissertations
Arkansas has a climate and geography that allows for the production of unique horticultural crops, including hops (Humulus lupulus L.), blackberries (Rubus subgenus Rubus), and muscadine grapes (Vitis rotundifolia). These crops not only have potential for growers in Arkansas but have unique flavor and aroma attributes that impact marketability. Volatile compounds present in many different agricultural plants are the primary source of biologically-derived aromas and flavors. Therefore, the volatile and other quality attributes of hops, blackberries, and muscadine grapes were evaluated at the University of Arkansas (UA System) Division of Agriculture. The quality, volatile, and sensory attributes of four hops …

Techniques To Enhance The Attributes Of Wines Produced From Grapes Grown In Arkansas, Sarah Mayfield
Graduate Theses and Dissertations
Grapevines (Vitis spp.) are one of the most widely-planted horticultural crops, and the United States plays a major role in grape and wine production. Arkansas has a long history of grape and wine production with grapes grown in Arkansas including mostly native species, such as muscadines, and hybrids (crosses of Vitis spp.), such as Chambourcin. In addition, the University of Arkansas System Division of Agriculture (UA System) grape breeding program has cultivars and selections that have shown potential for wine production. The objectives of this research were to: evaluate effects of specific inactivated yeast application to Chambourcin grapevines on attributes …
Phylogenetic Diversity Of Arkansas Vineyard And Wine Microbiota, Natacha Cureau
Phylogenetic Diversity Of Arkansas Vineyard And Wine Microbiota, Natacha Cureau
Graduate Theses and Dissertations
Microorganisms inhabiting the soil, leaves, and grapes in vineyards influence the terroir, a set of environmental factors that impact wine characteristics. Previously, the main method to identify microorganisms was to culture on different media, but a large portion (> 99%) could not be cultured and were consequently unidentified. However, the emergence of new molecular tools has enabled further study and identification of microorganisms such as indigenous vineyard microbiota. The objective of this research was to investigate the phylogenetic diversity of Arkansas vineyard and wine microbiota using high-throughput sequencing. In terms of the Arkansas vineyards, the fungal and bacterial diversity of …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender
Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender
Student Theses 2015-Present
This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Geographic Classification Of Wines Using Their Elemental And Water Isotopic Composition; Special Emphasis On Washington State, Usa, Shirley Orellana
All Master's Theses
The frequency and scope of wine fraud cases have increased worldwide, leaving wineries vulnerable to damage in reputation and potential lost revenue. In the United States of America, Washington State (WA) is the second-largest premium wine producer where wine fraud could have a significant impact on the industry. In an effort to reduce this risk, advanced analytical instrumentation and statistics were employed to chemically characterize, and thus geographically classify, 118 wines from 4 major wine producing regions located on 3 continents, including 64 wines from WA. Focus was on the analysis of inorganic and chemically stable tracers that are conserved …

Over 500,000 tons of organic materials such as food scraps are disposed of each year in Wisconsin. A large percentage of this material could be composted or turned into useful products.5 The purpose of this article is to educate farmers and organizations on how to turn food waste into a high value food source for livestock. Yeast can be grown at any time of the year without the large inputs of agricultural chemicals and machinery that is common with other feed production methods. A yeast growing facility can be scalable to any size the producer wants such as a small …
Efficacy Of Ultraviolet Radiation To Control Lactic Acid Bacteria In Wine Must, Brian D. Williams
Efficacy Of Ultraviolet Radiation To Control Lactic Acid Bacteria In Wine Must, Brian D. Williams
All Master's Theses
The use of shortwave ultraviolet (UVc) radiation to control lactic acid bacteria (LAB) in wine production was studied. A simulated wine sterilizer was built using a commercially sourced ultraviolet (UV) sterilizer commonly used in aquariums and ponds. After growing cultures in test tubes, samples of five different species of LAB were introduced into white grape juice adjusted for brix and pH to match that of wine must commonly found in the Yakima Valley American Viticultural Area. The mixture was then agitated and allowed time to evenly distribute the bacteria throughout the juice. The juice was sent through the …

La demanda de vino en Colombia está en aumento, pero la industria vitivinícola nacional no cuenta con la infraestructura para satisfacerla, ni en capacidad ni calidad. La producción de vinos es solo el 0,7% dentro de la industria de licores nacional. Tradicionalmente el vino se elabora de uva, pero se ha podido obtener vino a partir de otras frutas, utilizando el proceso de vinificación en blanco. En Colombia la producción de frutas tropicales se facilita por su ubicación geográfica y climas; una de ellas es el mango, que en el año 2012 tuvo una producción de 311.920t y el 20% …
