Sealing a bottle under a screw cap removes the variability and taints associated with cork. A screw cap also ensures that the wine in the bottle will age under the best possible conditions. The perfect seal of the screw cap ensures that no air or oxygen can enter the bottle. In these reductive conditions the wine undergoes ”pure bottle aging” where the fresh citrus flavours remain, and are overlaid with flavours of toast, lemon grass and eventually some honey and possibly marmalade. Since there is no oxygen getting in to the bottle, there is no oxidising or ”drying out” of the wine. This means that the colour, while it will deepen into the gold spectrum, retains its freshness and green hues and does not go brown, and that the flavours and palate do not ”dry out”, but stay fresh with any sweet fruit characters that were initially in the wine remaining. The 2006 Pewsey Vale Contours Riesling is a rich and intensely flavoured wine. It has a still pale straw colour with hues of green. Intense but restrained classic fruit aromas of lemons, with a hint white flowers, influenced now with the first sings of bottle aged toast and lemon grass. The palate shows great length and depth with limes, dried rosemary and a hint of lemon grass. The wine finishes with a fresh natural acidity which balances the flavour intensity.
