Iowa Wine Industry And Its Educational Needs, Aude A. Watrelot

The Journal of Extension

The grape and wine industry in Iowa is based on non-Vitis vinifera grapes, which are not well-known and come with their own set of challenges. An industry survey revealed that wine business and marketing are the main concerns for the Iowa grape and wine industry members. The educational resources already provided by Extension personnel were highly appreciated and events should be offered in several locations around Iowa. The main topics of roundtables and discussions should be about vineyard management and winemaking practices, specifically practices to avoid microbial spoilage, to reduce wine acidity and to select appropriate yeasts for fermentation.

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 …

Vineyard Age Effect On Juice Chemistry, Anthocyanins, And Total Phenolics, Eric L. Camera

Wine and Viticulture

Grapevines (cv Zinfandel) planted in the same vineyard 100 years apart were analyzed for juice chemistry and phenolic content of the fruit. The vineyard was dry farmed, and vines from the original 1890 vineyard were compared to vines inter-planted in 1990. As “old vine” wines can command higher prices in the market due to a perceived difference in fruit characteristics. This study attempted to observe if there was a measurable difference in fruit characteristics, or if it is simply an effective marketing strategy. There has been little research conducted in the wine industry attempting to observe a difference of old …

Effect Of Smoke In Grape And Wine Production, Kristen Brodison

Bulletins 4000 -

Smoke exposure of grapevines and the development of smoke-related characteristics in the resulting wines is an increasing issue for the wine industry. As Australia faces a warming climate with more bushfires, smoke exposure in vineyards is becoming more regular.

Wines made from grapes exposed to smoke during sensitive growth stages can exhibit aromas and flavours resembling smoked meat, disinfectant, leather, salami and ashtrays. Where unfavourable smoke characteristics are detected by consumers at high concentrations the wine may be unpalatable. Unsalable wines result in financial losses for producers with costs flowing on to wine brands, market presence and future sales.

Selections Of The Houghton Clones Of Cabernet Sauvignon, Glynn Ward, Ian Cameron, Richard Fennessy

Bulletins 4000 -

Cabernet Sauvignon is the premium red wine grape variety grown in Western Australia. The high quality wines produced have won prestigious awards and accolades nationally and internationally. The first clonal selection of Cabernet Sauvignon in Western Australia was conducted by the Department of Agriculture at the Houghton Vineyard in the Swan Valley from 1968 to 1970. The objective was yield improvement, vine health and fruit flavour. Twenty-one high performing vines were identified from vines planted in Houghton Vineyard in the 1950s as cuttings sourced from vines planted in the 1930s. These high performing vines became known as the ‘Houghton clones’. …

Evaluation Of Alternative Wine Grape Varieties In Manjimup, Western Australia, Kristen Kennison, Richard Fennessy

Bulletins 4000 -

Since 1998 the Department of Agriculture and Food, Western Australia (DAFWA) in conjunction with the Western Australian Vine Improvement Association (WAVIA) have imported over 60 new varieties and clones of wine grape material into Western Australia. These new varieties and clones were identified by the wine industry as having both domestic and international wine market potential to enhance the production and development of premium WA wine.

The grapevine material is currently located in the Foundation Collection at the Manjimup Horticultural Research Institute (MHRI). In 2003 a trial of 18 of these varieties was established in order to gain an understanding …

Considerations For Starting A Winery, Justin R. Morris

Research Reports and Research Bulletins

This publication is for anyone who has ever considered entering the wine industry. The goal of this publication is to provide information about requirements and procedures for starting a winery. It is not a “how-to” manual but rather is designed to serve as a starting point to investigate the many aspects of owning and operating a winery. Although the manuscript frequently refers to procedures for starting a winery in Arkansas, the concepts presented are applicable throughout the U.S. Detailed economic information on starting a winery is covered in a companion publication. Both publications are part of a project supported by …

Organic Grapes And Wine : A Guide To Production, Gerry Parlevliet, Steven Mccoy

Bulletins 4000 -

The tastebuds, health concerns and environmental conscience of affluent consumers are demanding more organically grown food than producers worldwide can supply. Growing consumer concerns about the effects of synthetic chemical pesticides and fertilisers on human health and the environment have boosted world trade in organic products by a rate of about 20-30 per cent a year for the past 10 years. World trade was estimated to be worth $US 21.6 billion in 2000 and is expected to reach US$100 billion by the year 2006.

The Australian market for organic products alone is valued at $200-$250 million - with exports estimated …

The Function And Use Of Sulphur Dioxide In West Australian Winemaking, D Mann

Journal of the Department of Agriculture, Western Australia, Series 4

THE judicious use of sulphur dioxide is perhaps the most important of the fundamentals of winemaking in a hot climate.

Western Australia's vintage, centred in the Swan Valley just a few miles north-east of Perth, is subjected to some of the highest summer temperatures experienced by a quality wine producing district.

In this environment, it is important to make good use of sulphur dioxide to avoid wine spoilage.
