Whatever way I look at it, I just can't get past the value on offer. Finding any $20odd Adelaide Hill Chardonnay's is not any easy process.  It's a premium region and demand is high.  This Bleasdale Chardonnay is a real find - it's from Halliday's Winery of the Year, it's got the big 96 point rating, it's from Adelaide Hills. Here is Halliday's review from the Companion:

"Whole-bunch pressed direct to French oak puncheons (25% new) for fermentation on full solids including wild mlf; 9 months' maturation. Brilliant quartz-green. All the inputs have been precisely managed, notably the mlf. The bouquet and palate move hand in hand, white peach/nectarine and citrusy acidity running throughout, oak a mere servant."  James Halliday 

As you can imagine, deals like this sell out quick, so don't delay your purchase.
