Oak Barrel Aging of Red Wines
Traditionally, great red wines are aged in oak barrels from the end of fermentation until bottling. The first motivation in choosing barrels was probably that they were easy for one man to handle and could also be used for shipping. It was not until some time later that their positive effect on wine development, in terms of color, clarity and flavor, came to be appreciated. However, the use of ...
متن کاملGenetic structure inside a declining red oak community in old-growth forest.
Problems with oak regeneration have been documented in the last 50 years at numerous sites in the Midwestern United States. We applied nuclear microsatellites to examine the demographic and fine-scale spatial genetic structure of red oaks in two old-growth stands in Indiana. Oaks in one stand have declined in numbers over the past several decades whereas oaks in the other, smaller stand have in...

15 صفحه اولPhenolic Extractives in Southern Red Oak Bark
The bark of southern red oak (Quercus falcala Michx. var. falcala) is a rich source of quercitrin (quercetin3-rhamnoside). It contains only low concentrations of (+ )-catechin and no significant amounts of epicatechin or gallocatechin. The three major dimeric proanthocyanidins present are epicatechin(4f,>8)-catechin, catechin-(4a>8)-catechin and the 3-gallate ester of epicatechin-( 4~>8)-catech...
متن کاملDendrochronological parameters of northern red oak (Quercus rubra L. (Fagaceae)) infested with red oak borer (Enaphalodes rufulus (Haldeman) (Coleoptera: Cerambycidae))
Oak-dominated forests in northwestern Arkansas have recently experienced an oak mortality event associated with an unprecedented outbreak of a native insect, the red oak borer, Enaphalodes rufulus (Haldeman). To determine whether prior drought was associated with increased E. rufulus infestation level of Quercus rubra L. trees, we employed a suite of dendrochronological measurements from Q. rub...
