YAN’s or Yeast Assimilable Nitrogen represent the Nitrogen available for the wine yeast to use during fermentation. YAN levels are important for a whole range of reasons in winemaking and if low and not corrected can lead to various wine faults. Last year Dinny highlighted chronic low YAN levels in the Riesling block over the last several years, so we set up a plan which included compost under the vines and a Liquid Compost Plus application pre-flowering and wham!...levels have gone from 2016 – 86mg/l, 2017 – 104, 2018 – 72 and this year with compost and spray 253mg/l!! Exactly where it should be. How good is this year’s Riesling going to taste now!!
Rowing up compost at Idyll Wines. Compost is just part of an approach. Our philosophy is that if you do more of the things that enhance soil biology like using compost, use soil/plant friendly sprays like compost extract, fish or sea weed, plant cover crops, encourage biodiversity and less of the things that can decimate soil biology like constant ripping and tillage, use of synthetic fertilisers, herbicides and pesticides, then slowly the overall health and quality of your vines will improve.
Dinny Goonan makes award winning Riesling. We reckon it’s a winner too. It was great to hear his feedback after putting Compost down in early Spring and a dose of Liquid Compost Plus just before flowering.
"The Riesling vines have never looked better with a large lush green canopy. They cruised through the heat spikes of January with no signs of heat stress at all."

New telehandler arrived this will continue to improve the quality of our compost.
We did ask them to put it near the bollard I guess...

A great and well attended day at Lethbridge wines with soil scientist Declan McDonald and Debortoli vineyard manager Rob Sutherland talking about some of the positive outcomes they have measured using compost under vine.

An intimate session with Soil Scientist Declan McDonald was held at Surf Coast Hotel discussing compost application and soil testing.
Whilst agriculture and compost is a focus of our business, we’re also passionate about recycling. We have been recently engaged to see if we are able to ‘clean up and process’ City of Greater Geelong’s street sweepings using some of the processes we have developed in composting.
Currently around 3,500 Tonnes of Sweepings are being dumped into landfill. Hopefully through our trial we can set up a process that will reduce this landfill figure by up to 90%.”
