Analysts have given a thumbs up to brewer Lion Nathan's acquisition of the small South Australian Banksia winery.

Although Banksia was a small, regional operation with likely neutral impact on the brewer's earning per share in the short term, analysts have approved projections expecting Banksia to grow at a compound rate of 20% a year for the next four years.

With the earlier uproar surrounding its attempts to buy the New Zealand winery Montana the Banksia acquisition was seen as a positive outcome, highlighting the company's determination to pursue premium, branded niche producers such as Banksia's Tatachilla and St Hallett portfolios.

It was also seen as important given the maturity of the Australian New Zealand beer market.
