 At Kuleski, we're sustainable across all aspects of the business. I guess fundamentally it starts off in the vineyard. So we've been certified organic and biodynamic since 1998 on the property here. So what that means is by fundamentally not using any chemicals in the vineyards, no chemicals. Pesticides, herbicides, fertilisers, things like that. It's all about getting the health of the soil in balance. So promoting good fungi, bacteria, earthworms and so forth. We're getting quite a few people that are really interested to come out to the farm, have a look around. Of course we're talking through the winemaking process, which is relatively straightforward and traditional. But we like to show them the compost heap, get them to weather permitting, touch and feel. That have a sniff of it, it really smells quite sweet, almost good enough to eat. So I think people can then really understand the basics and what we're trying to do there in getting the soil healthy and balanced. So we're talking through that, walking through the winery. And then of course we have also got a solar system, so it's self-sufficient for power. And we've got quite a large catchment from the point of view of rainwater. So self-sufficient for water as well. For the actual wine point of view I think it means it makes potentially better quality wine and more authentic wine, which really represents the time and the place where it's growing. So I guess wine is all about where it's growing, the soil. And by growing it nice and naturally organically, by dynamically, I think you get the best expression of that soil. So then that the characters come through in the wine. It's really showing our Kaleski winery, our Kaleski wine, as opposed to just a generic wine from wherever, which I think using conventional methods can dilute the authenticity of that wine. You look at the food side of things and a lot of people are eating organically or eating foods with no preservatives, less preservatives. So people are becoming much more aware of how their choices affect their health and affect the environment. So we're seeing that from a wine point of view as well.
