CHARDONEL – Still Wine Styles CHARDONEL – Still Wine Styles MEETING NOTICE The topic for our January meeting is "Chardonel Still Wine Styles". Fifty-nine wineries in Missouri produce wine using the Chardonel grape (1) , making it one of the most popular regional wines. Amateur wine makers in Missouri are fortunate that high quality Chardonel grapes are available from local vineyards. Steve Brunkhorst will lead the meeting, and will share his 2014 vintage Chardonel wines. We will taste his Chardonel produced in glass without flavor or aroma modification, and compare it to the same base wine produced with malolactic fermentation as well the same base wine aged with American oak. We will also taste Chardonel wines from several Missouri wineries.

SOURCE www.hort.cornell.edu CHARDONEL – Still Wine Styles “This hybrid grape is a cross of the famed Chardonnay grape with the popular Seyval Blanc. Chardonel can be fermented in oak or stainless steel barrels, and the grapes produce a dry and full bodied wine. Depending on aging techniques, this hybrid may exude notes of oak, butter or citrus fruit. “ SOURCE www.MissouriWine.org CHARDONEL – Still Wine Styles THIS MEETING TASTING COMPARISONS Amateur Produced Chardonel Still Wine made in several styles Free-Run-Juice Press-Run-Juice OAK MLF Fermented & Aged in Glass Missouri Commercially Produced Chardonel Still Wines Stainless Steel Fermented or Aged in Oak Barrels CHARDONEL – Still Wine Styles Tasting Sequence 1 2 4 3 Free Free Free Press Steve’s Wine Run Run Run Run Naked Oak MLF Oak Oak + MLF 5 Oak Oak Naked Commercial barrel barrel batonnage 6 7 8 CHARDONEL – Still Wine Styles How Were the Styles Managed in the Cellar Free Run – juice collected without pressing, hand stirring only Press Run – juice collected with soft press post free run collection Naked – fermented & aged in glass, no oak, no MLF CHARDONEL – Still Wine Styles 2014 Chardonel ….Exceptional Condition Nice Chardonel Bunch – note “shoulders” CHARDONEL – Still Wine Styles CHARDONEL – Still Wine Styles Sun Canopy & Fan Provide some relief from heat Homemade crusher.

Bâtonnage is part of the sur lie process. After fermentation, the spent yeast cells drop to the bottom of the barrel, and the cellulose in the yeast cell walls starts to degrade. Through this process a number of polyphenols are released, many of which are flavor components, while others account for that wonderful creaminess that you experience with our Reserve Chardonel… Burgundian in style white wine, with aromas of peach, citrus, a hint of vanilla, and a creamy mouth feel, aged and fermented in French Oak Barrels.

    Matching Grape Varieties to Sites Are hybrid varieties right for Oklahoma? Bruce Bordelon Purdue University Wine Grape Team 2014 Oklahoma Grape Growers Workshop 2006 survey of grape varieties in Oklahoma: Vinifera 80%. Hybrids 15% American 7% Muscadines 1% Profiles and Challenges…continued… • V. vinifera cultivars are the most widely grown in Oklahoma…; however, observation and research has shown most European cultivars to be highly susceptible to cold damage. • More research needs to be conducted to elicit where European cultivars will do best in Oklahoma. • French-American hybrids are good alternatives due to their better cold tolerance, but have not been embraced by Oklahoma grape growers... Reasons for this bias likely include hybrid cultivars being perceived as lower quality than European cultivars, lack of knowledge of available hybrid cultivars, personal preference, and misinformation. Profiles and Challenges…continued… • The unpredictable continental climate of Oklahoma is one of the foremost obstacles for potential grape growers. • It is essential that appropriate site selection be done prior to planting. • Many locations in Oklahoma are unsuitable for most grapes, including hybrids and American grapes. • Growing grapes in Oklahoma is a risky endeavor and minimization of potential loss by consideration of cultivar and environmental interactions is paramount to ensure long-term success. • There are areas where some European cultivars may succeed. • Many hybrid and American grapes are better suited for most areas of Oklahoma than

They are grown in home gardens for fruit and landscape the lives of New purposes or commercially for wine, raisins, or fresh consumption as “table” grapes. A cultivated variety, or “cultivar,” is a formal term for Mexicans through variety. Variety is the more common term, and will be used in this publication. Selecting grape varieties that are adapted to prevailing academic, research, climatic and soil conditions is an important step before planting. Very few locations above 6,000 feet in elevation are successful grape pro- and Extension duction sites. Suitable growing conditions at lower elevations are still very site-specific due to the major threat to grape culture: winter or programs. frost injury. Winter injury occurs at subfreezing temperatures during vine dormancy when no green tissue is present. Frost injury occurs at subfreezing temperatures when green tissue is present. A variety’s win- ter hardiness, or ability to withstand cold temperatures, depends on its genetic makeup or “type.” In addition to winter hardiness, other considerations when selecting a variety are its fruit characteristics, number of frost-free days required for ripening, disease susceptibility, yield potential, growth habit, and other cultural requirements.

Owing to the superior quality of their grapes, these cultivars were long considered the only suitable for the production of high quality wines. However, the lack of resistance genes to fungal diseases like powdery and downy mildew (Uncinula necator and Plasmopara viticola) makes it necessary the application of huge amounts of chemical products in vineyard. Thus, the search for alternative and more sustainable methods to control the major grapevine pathogens have increased the interest in new disease tolerant varieties. Chemical characterisation of these varieties is an important prerequisite to evaluate and promote their use on the global wine market. The aim of this project was to produce a comprehensive study of some promising new disease tolerant varieties recently introduced to the cultivation by identifying the peculiar aspects of their composition and measuring their positive and negative quality traits.

    VERAISOŃ TO HARVEST Statewide Vineyard Crop Development Update #5 October 6, 2017 Edited by Tim Martinson and Chris Gerling Around New York... Statewide (Tim Martinson) Harvest is in high gear throughout New York, with 27 of our original sample blocks now harvested (Fruit composition table pp. 6-10). This includes many traditional natives and hybrids (Baco noir, Seyval blanc, Vignoles, and Niagara), almost all of the Cold-hardy Minnesota hybrids (Marquette, Frontenac, and La Crescent), and early vinifera (Pinot noir and Chardonnay). Overall, the pace of ripening (by the numbers) slowed down from last week. Across all varieties, soluble solids gained an average 1 °Brix, and TAs dropped by 1.2 g/l. (Last week +1.3 °Brix; -1.65 g/l TA). Biggest gainers in our Burdett, NY. Young Riesling vines with first partial crop at Paul Hobbs samples included Concord, Catawba, and La Crescent vineyards, on the southeast end of Seneca Lake, near Burdett. (>2 °Brix), with mid/late season varieties gaining about Photo by Tim Martinson +0.5°Brix. Most TAs changed by <-1 g/l, but acids dropped dramatically in Catawba and Vidal blanc (both>-3g/l). Compared to last year, most varieties are still 1 to 3 °Brix The number of calls concerning the ability of vines to ripen lower than 2016, and TAs range from 1-5 g/l above last a crop are increasing.
