The business is run by Jim's son Peter these days and, with a significant acreage of priceless old-vine vineyards, he continues the twin traditions of excellence and innovation.
"In the wine game you've always got to bring in new customers. You lose 10 per cent every year for all sorts of reasons," says Jim.
He treats the vines like family and is full of knowledge and enthusiasm about what sites are producing what particular style of wine.
"With our Florita riesling we've found that after 30 years these wines are now developing marmalade characters ... whereas our Lodge Hill riesling is 480m above sea level, one of the highest vineyards in the Clare Valley, and with the cool nights and warm days it gives us flavours that are more restrained and elegant."
The first vintage of The Armagh was 1985 and New Zealand was its first export market.
"In 1987 we got the wines into Antoine's fine dining restaurant in Parnell," recalls Jim.
"Tony Astle took The Armagh, along with a selection of others, on his wine list. That was the start of building the brand in New Zealand."

2012 Jim Barry Lodge Hill Riesling - $25
If you prefer your riesling bone dry, then this is perfect, from fruit that is well shaded and not overly ripe. With lots of lemon twist flavour and a teeth-clenching bite.
2010 Jim Barry The Cover Drive - $25
A big seller in New Zealand, this 100 per cent cabernet sauvignon is not as overwhelming as you might expect. It has lots of red fruit flavours with a hint of mint and earthiness. This is good value and a perfect alfresco summer red for the barbecue.
