-Dry Farming-

Since 2011, most of our vineyard has been dry-farmed, except for very dry season. (So far we irrigated 8 hours total in 2016 vintage, due to very dry early spring)
We only irrigate for the young vines to establish their root system.
We believe that there are several benefits, for both wine-style and environment, not to irrigate in the vineyard.

Vintage Variation
Raining pattern is one of the most important factor to shape the characteristic of vintage.
We would like to produce the wine which represent the vintage.
There are more detailed information about different vintage on Wines page on our website.

Terroir Expression
Root system tends to stay in the area where irrigation water is available.
To express the terroir where you grow your vine, we believe it is important to have broader root system.

Smaller Canopy
When it comes to Sauvignon Blanc from Marlborough, Methoxypyrazines is one of the most important chemical compound, which contribute to herbaceous flavour.
Since Methoxypyrazines are by-products of photosynthesis, they require larger canopy, more leaves, to create higher Methoxypyrazines. Without irrigation, our wine tends to have less Methoxypyrazines. This allows us to produce different style Sauvignon Blanc from this region.

Save Water
According to the study by New Zealand Winegrowers, average irrigation in 2014/2015 vintage was 660L/vine. If it is a normal vineyard with 2,000 vines to the ha, it requires 1,320,000L/ha. (Most of our vineyard is planted as 4,000 vines/ha)
Dry farming can reduce significant amount of irrigation water which normally comes from either river or from aquifer.

However there are some disadvantage of dry farming, that yield can be variable from year to year. It is our challenge as wine producer to be sustainable in both environmental and financial.


Since 2011, Folium Vineyard has been applying organic approach in the vineyard. We received organic certification from Biogro since 2013 in the vineyard. All wines from 2018 vintage areĀ  fully certified. ( Wines prior to 2018 is not certified, simply because we haven’t gone through with certification process.)

-Light Weight Bottle-

Reducing greenhouse gas emission is urgent issue which all of us need to enrol. Glass bottle is one of the major emissions in our industry. Some of the studies mentioned 45.6% of greenhouse gas emission is in wine industry coming from Glass production (da Silva et al. 2022).
Choosing lighter weight bottle or even alternative packaging can reduce significant amount of emission of wine production.
We have decided to move to lighter weight bottle for Estate Sauvignon Blanc from 2022 vintage, and Estate PN from 2021 vintage. Our original bottle was 545g per bottle, and new bottle is 417g pre bottle. This is 23.4% reduction in the grass weight. If glass bottle is taking 45.6% of our greenhouse gas emission, this weight reduction in bottle can actually reduce 10.6% of emission of total business.
