Tom pressed his winning cider for this year’s contests with a bladder press using Jonathan and Fuji apples. Second Place Illinois Cider and 2nd Place National Cider went to Joe Ringhausen of Ringhausen Orchards in Fieldon, IL. Trevor Grissom of Grissom’s Lost Creek Orchard in Greenup, IL won Third Place Illinois Cider. Tom Roney of Tuttle Orchards won 3rd Place National Cider. Midwest Cider of Merit 1st Runner-up was awarded to Raoul Bergersen of Valley Orchards in Winnebago, IL. Pat Curran of Curran’s Orchard in Rockford, IL was awarded the Midwest Cider of Merit 2nd Runner-up and the Midwest Cider of Merit 3rd Runner-up went to Craig Tanner of Tanner’s Orchard in Speer, IL.

  • Apples Catalogue 2019
    ADAMS PEARMAIN Herefordshire, England 1862 Oct 15 Nov Mar 14 Adams Pearmain is a an old-fashioned late dessert apple, one of the most popular varieties in Victorian England. It has an attractive 'pearmain' shape. This is a fairly dry apple - which is perhaps not regarded as a desirable attribute today. In spite of this it is actually a very enjoyable apple, with a rich aromatic flavour which in apple terms is usually described as Although it had 'shelf appeal' for the Victorian housewife, its autumnal colouring is probably too subdued to compete with the bright young things of the modern supermarket shelves. Perhaps this is part of its appeal; it recalls a bygone era where subtlety of flavour was appreciated - a lovely apple to savour in front of an open fire on a cold winter's day. Tree hardy. Does will in all soils, even clay. AERLIE RED FLESH (Hidden Rose, Mountain Rose) California 1930’s 19 20 20 Cook Oct 20 15 An amazing red fleshed apple, discovered in Aerlie, Oregon, which may be the best of all red fleshed varieties and indeed would be an outstandingly delicious apple no matter what color the flesh is. A choice seedling, Aerlie Red Flesh has a beautiful yellow skin with pale whitish dots, but it is inside that it excels. Deep rose red flesh, juicy, crisp, hard, sugary and richly flavored, ripening late (October) and keeping throughout the winter. The late Conrad Gemmer, an astute observer of apples with 500 varieties in his collection, rated Hidden Rose an outstanding variety of top quality.

Since a growing number of consumers are increasingly seeking safe and healthy food options, alternative fruit production systems such as organic farming, and their potential to provide safe and nutritious foods, have been gaining increasing attention in the last decades. The aim of the presented study was, therefore, to analyse and to compare the concentrations of selected health-promoting antioxidants, such as phenolic acids, flavonols, and vitamin C, in fruits of three apple cultivars (Champion, Gala, and Idared) grown in conventional and certified organic orchards in Poland. All analyses were performed using the high-performance liquid chromatography (HPLC) method. Organic apples tested within the study, compared to the conventionally grown ones, were characterised by significantly higher concentrations of phenolic acids (av. >31%) and flavonols (av. >66%) with the identified differences being consistent in all three cultivars and two seasons.

  • Dusting Versus Spraying Apple Orchards in Ohio
    BULLETIN 527 AUGUST, 1933 Dusting Versus Spraying Apple Orchards in Ohio F. H. Ballou and I. P. Lewis • OHIO AGRICULTURAL EXPERIMENT STATION Wooster, Ohio This page intentionally blank. DUSTING VERSUS SPRAYING APPLE ORCHARDS IN OHIO . INTRODUCTION F. :U:. BALLOU .AliD I. I'. LEWIS In response to a special request from the organized fruit growers of Ohio the Department of Horticulture of the Ohio Experiment Station began, in the spring of 1926, a series of experiments in dusting versus spraying apple orchards for prevention of injury to foliage and fruit by fungous diseases and insect pests. This series of dusting versus spraying experiments was carried on in eastern, central, northeastern, and southeastern Ohio. The five widely separated projects were located as follows: The Belmont County Experiment Farm, the Dale View Test Orchards (Licking County), the Mahoning County Experiment Farm, the Southeastern Experiment Farm (Meigs County), and the Washington County Experiment Farm. The orchards in Belmont, Licking, and Washington Counties are very favorably situated in hilly sections of the State and, for the most part, occupy areas of ground of such elevation as affords unusual frost protection to buds, blossoms, and newly set fruit. No losses of fruit from cold occurred in these orchards during the full term of the experiment. The orchard at the Mahoning County Experiment Farm occupies ground of moderate elevation, which affords fairly satisfactory cold-air drainage. In the spring of 1929 a partial loss of the apple crop was sustained by reason of freezing temperature immediately preceding the period of open blossoms. However, there was sufficient production of fruit to permit securing grades and counts in all of the variously dusted and sprayed plots.
