While the definition of natural wine seems as manifold as there are vintner’s making it, Duncan would like to state for the record that his philosophy of Natural Wine is wine that begins in an ideal vineyard, is hand-picked, gently pressed, fermented with natural yeasts, unfined, unfiltered, aged and sealed with cork. The wine should be very stable and not liable to spoil. Ideally, the energy used should be sustainable sourced also. He recommends all the free solar energy that vintner’s have at their disposal during vintage should be harnessed with photovoltaic (PV) panels.
1. The Vineyard – must be not irrigated. This means that the fruit does not uptake artificial moisture as from dammed water or bore water. This means that the water is sourced by the (quite resourceful) vines – making for a high quality fruit harvest. The vines are hand-pruned and dressed, de-leafing is carried out to reduce fungicide spraying and the fruit is hand-picked when the sugar level is optimal for good wine-making.
2. For a natural dessert wine, the fruit should be picked late in the season and very high in sugar. It is de-stemmed and crushed before ferment starts via natural yeasts (another gift from the Gods of wine). Thereafter the must is pressed by any means practicable. Duncan uses a basket press, to extract the partially fermented juice.
3. The wine should be unfined and unfiltered. There is a saying,” Good wine falls bright”. This means very little to no sediment most of which can be avoided by age settling prior to bottling and decanting after opening on the part of the consumer. Any protein haze is a natural part of the process of maturation.
4. The wine should be sealed with cork as it is a natural sustainable product. Cork is a renewable resource and uses 1/2 the electricity to produce, and hence half the CO2. Unfortunately electrical energy is cheap and screw caps are about half the price of corks.
In conclusion, natural wines are better for you and the environment. Enjoy in moderation.
