00:00As Canberra's cool climate wine region warms, these vines could produce the wines of the
00:08future.
00:09Directly behind me is Albarino and we've also planted Mentia and Paraletta.
00:13Spanish, white and red grape varieties planted at Mount Majuro Vineyard around two years
00:18ago, designed to future proof what goes in the bottle.
00:22We're looking for varieties that will have a longer ripening period and be more suited
00:27to a slightly warmer climate.
00:28Bureau of Meteorology data shows that average spring temperatures have been rising.
00:32If we look at the last 20 years, we've also seen an increase between 1.3 and 1.7 degrees
00:37and that's quite a lot in maximum temperatures.
00:40Summer now starts sooner and lasts longer.
00:43What we're seeing is that the temperatures that we used to associate with summer, maybe
00:4750 or even 30 years ago, those temperatures are happening now in spring.
00:51The effects of climate change have been steadily and noticeably changing Mount Majuro's wine
00:56production.
00:57Based on the data that shows over the last 20 years, we've seen greater than 30 days,
01:03maybe 40 days shortening of the season for Chardonnay.
01:07So we're harvesting it up to 40 days earlier than we did when we first started.
01:11For winemaking, an earlier, hotter spring means an earlier, shorter harvest.
01:16This can cause a crunch on resources like picking and processing, but crucially the
01:21wine just isn't as good.
01:23If it gets too hot, what will happen is we'll see fast ripening and we end up with sugar
01:28accumulation and our acid drops out, but we don't have flavour ripen as well.
01:33Majuro will continue to plant lesser known climate change tolerant varieties in the coming
01:38years.
01:39In time, consumers may have to change their palate.
