Accepted 29.08.2020) SUMMARY Noble rot wine is a specific type of sweet wine that derives from the infection of grape berries by a fungus called Botrytis cinerea. These wines are produced in specific wine regions around the world, with Sauternes region of France and Tokay region of Hungary being the most famous ones. The purpose of the current article is to provide a systematic review on the different stages of botrytized wines production, including a detailed analysis of the technical aspects involved. Specifically, it describes the process and development of berry infection by B. cinerea, and special emphasis is given to the main stages and operations of winemaking, conservation, aging and stabilization. A complex combination of a number of parameters (e.g., very specific environmental conditions) explains the rarity of noble rot occurrence and highlights the uniqueness of botrytized wines. RESUMO Os vinhos botritizados representam uma categoria específica de vinhos doces, sendo obtidos a partir de bagos de uva infectados pelo fungo Botrytis cinerea, através de um processo designado por podridão nobre. Estes vinhos são produzidos em regiões específicas do mundo, sendo Sauternes e Tokay, originários de França e Hungria respectivamente, os exemplos mais conhecidos a nível mundial.

Epidemiology of Grape Powdery Mildew, Uncinula Necator, in the Willamette Valley
An Abstract of the Thesis of Tyrone W. Hall for the degree of Master of Science in Botany and Plant Pathology presented on February 07,2000. Title: Epidemiology of Grape Powdery Mildew, Uncinula necator, in the Willamette Valley. Redacted for Privacy Abstract approved: W Iter F. Mahaffee An important disease of Vitis vinifera production in Oregon and all other commercial growing regions is powdery mildew of grape, caused by the obligate fungal pathogen Unci nula necator (Schwein.) Burril. Grape production can be characterized as a long-term investment in the establishment and maintenance of the vineyard. Establishment times have been reduced with the use of plastic vine shelters, but powdery mildew disease pressure within vine shelters had been an unaddressed issue. Control of the pathogen requires frequent spray applications and costly cultural management of the grape canopy. Industry interest in forecasting programs have shown promise in regulating spray applications to times when they are most effective, or needed. The timing of when to begin spray programs is believed to be a point of weakness in the forecasting programs currently available for grape powdery mildew. The influence of vine shelter use on the development of powdery mildew was investigated in the field during the 1998 and 1999 growing season. Industry standard installations of various brands of vine shelters were tested against modified installations for both incidence and severity of Uncinula necator infection. The industry standard installation of76 ern high tubes hilled with 8 ern of soil at the bottom to prevent airflow, were effective in reducing the incidence of powdery mildew in both field seasons.

Studies on the Storage Rot of Sweet Potato
STUDIES ON THE STORAGE ROT OF SWEET POTATO (IPOMOEA BATATAS L & LAM) BY BOTRYODIPLODIA THEOBROMAE PAT. AND OTHER FUNGI By Anthony Elue Arinze B.Sc., M.Sc. (Lagos) a A thesis submitted in part fulfilment of it) the requirements for the Degree of Doctor of Philosophy of the University of London. Department of Botany and Plant Technology Imperial College of Science and Technology Field Station Silwood Park Ascot Berkshire U.K. AUGUST, 1978 - 2 - ABSTRACT The storage rot of sweet potato (s.p.) (Ipomoea batatas) tuberous roots by Botryodiplodia theobromae (B.t.), Botrytis cinerea (B.c.) and Cladosporium cucumerinum (C.c.) was studied. The tuber was susceptible to rot by B. theobromae but was coloni,ed to a limited extent by B. cinerea and C. cucumerinum. The role of pectic enzymes in the successful rotting of s.p. by B.t. was investigated. B.t. produced four PG isoenzymes in vitro one of which was recovered from rotted sweet potato tissue. The properties of these isoenzymes were studied. The possible interaction between the host's metabolites (phenols and oxidative • enzymes) and the pectic enzymes of B.t. was discussed in relation to the successful rotting of the tuber by the fungus. Comparatively little pectic enzyme (PG) was recovered from tissues inoculated with B.c. and no pectic enzyme was found in tissues inoculated with C.c. Low temperature treatment (0-7°C) of the tuber induced chilling injury rendering the tissues more susceptible to rot by the fungi. The accumulation of antifungal compounds by s.p. inoculated with B.t., B.c.

Botrytis Bunch Rot and Blight
Online Guide To GRAPEVINE DISEASES Virginia Tech Botrytis Bunch Rot and Blight Ashley L. Myers Grape Pathology Extension Specialist, Department of Plant Pathology, Physiology, and Weed Sciences, Virginia Tech AHS Agricultural Research and Extension Center, Winchester, VA Introduction: Botrytis bunch rot occurs in vineyards all over the world, but is most common in regions with cool to moderate temperatures during the preharvest period. Once considered a secondary disease, Botrytis is now one of the major fruit rot diseases of grapes. Botrytis seriously reduces the quantity and quality of the crop by causing premature cluster drop and postharvest fruit rot. In winegrape production, the most serious damage results from modified chemical composition of diseased berries resulting in wines that have off-flavors, are fragile, and are more sensitive to oxidation and bacterial contamination. However, in certain cultivars and under certain weather conditions, a specific form of botrytis cluster rot, known as “noble rot”, is a desired rot that contributes to the production of exceptionally sweet wines. Symptoms and signs: Buds and young shoots may be infected Photo by T. Wolf in early spring, turn brown, and then dry out with drier weather. At the end of spring but before bloom, large, irregular, reddish brown patches appear on a few leaves of the vine and are localized near the edge of the leaf blade or on major veins (Fig. 1). During humid or wet weather, these lesions may be covered with gray moldy growth characteristic of Botrytis. Before bloom Botrytis may invade flower clusters, and if Fig. 1 severe may cause entire clusters to dry out and fall off.

Compromised Fruit: Botrytis Bunch Rot
PROTOCOL RED WINE Compromised Fruit: Botrytis Bunch Rot VARIETY TYPE OF WINE Incidence of 5% or more of Botrytis cinerea and associated secondary Red Varieties infections. CHALLENGES OBJECTIVE • Oxidation • Off-aromas and flavors • Stuck fermentation • Organic acid depletion Mitigate the detrimental wine matrix alterations from fruit compromised by • Depletion of SO 2 Botrytis bunch rot. • Secondary Infection • Filterability • Biogenic amine • Mycotoxins KEY WINEMAKING STEPS WHEN DEALING WITH BOTRYTIS AFFECTED GRAPES: 1. Hand harvest and sort contaminated grapes in the vineyard. 2. Use adequate antioxidant and antioxidase protection to limit browning, color loss and aroma oxidation. 3. Reduce skin contact to limit extraction of off-aromas; avoid extended maceration and cold soak. 4. Supplement must with amino acids and ammonia to ensure complete healthy fermentation. 5. Press early and select yeast with low nitrogen requirements and fast, complete fermentation kinetics. 6. Promote fast extraction of polyphenols with EnartisZym Color Plus . 7. Remove any spoilage microbes as soon as possible. 8. If there is visual browning, use Enartis Claril SP to remove browning products. 9. Improve color intensity and stability by promoting condensation and co-pigmentation reactions. 10. Adsorb yeast inhibitors and some off-flavors and aromas with Celferm . 11. Balance wine mouthfeel with mannoproteins and fermentation tannins. 12. Late application of certain fungicides can increase elemental sulfur and metal content (Cu); test for metals and use Stabyl Met (PVI/PVP) to fine out excessive heavy metals. The above is achieved to the best of our knowledge and experience. Revision: August 2019 The industrial application of the advice provided does not imply any responsibility on the part of our company.
