Wine storage problems
Corking- a tiny percentage of bottled wine (abo t 1%) will s ffer from
this. The cork reacts with the wine and gives it a m sty, npleasant
taste. It is the most common wine storage problem and is ca sed by
harmless bacteria growing on the cork. As nfort nate as this is, there
is nothing to do b t to discard all of the wine in the affected bottle.
This is not to be conf sed with small fragments of cork floating in the
wine itself, which will not impair the flavo r.
Oxidisation- when wine has been opened and left for longer than a
day; it tends to lose its aroma and colo r, giving an overall flat taste.
The only way to avoid this, it to either drink the wine on the same day
it was opened or to se a vac m device specially designed for
removing oxygen from opened wine bottles. If yo se s ch a device,
the wine sho ld still be cons med shortly afterwards.
Ullage- this is loss of wine from the bottle by evaporation or leakage.
Signs of llage incl de wine seeping aro nd the cork, a protr ding cork
or a stained label. It can happen if the bottle has been allowed to get
too warm. The wine may still be drinkable, if the leakage was recent;
however, yo sho ld be aware that if the wine cools down again,
contraction can ca se more air to be s cked into the bottle and res lt
in f rther deterioration.
Slight effervescence in still wine- this isn’t really a problem with
the way the wine has been stored, b t as a res lt of incomplete
malolactic fermentation before the wine was bottled. A good way to
get rid of the effervescence is to let the wine breathe. Alternatively
yo can se a bottle vac m device, after abo t five min tes the
effervescence will vanish.
Sediment- this is not normally a problem, however both red and
white wines can prod ce sediment after a n mber of months in a
bottle. The sediment consists of tartrate crystals and is totally
harmless. If anything the b ilding of sediment can be considered a
good sign beca se it means that the wine was not s bjected to m ch
(if any) filtering, meaning that the flavo rs and aromas sho ld be
preserved better.
A good way to get aro nd sediment (if it is a problem) is to stand the
bottle pright, the day before opening, so that the sediment can settle
to the bottom of the bottle.
Yo can also decant yo r wine; decanting will “open p” the flavo r of
both yo ng and old wines, b t yo nger wines in partic lar. To decant,
po r the wine slowly and evenly into yo r decanter.
