The Australian Wine Research Institute

The April 2015 issue of Technical Review is now available online. Articles and abstracts can be viewed individually, or the full issue can be downloaded. For copyright reasons, access is available only to Australian winemakers and grapegrowers who pay the Wine Grapes or Grape Research levies. The new online Technical Review allows you to browse the list of the latest articles on grape and wine production by keyword, view article summaries and order journal articles from the AWRI Library.

Below is a snapshot of what’s in this issue:

AWRI Technical Notes	Glycosides contribute to in-mouth flavour releaseTracking Manganese levels in wine – an update
AWRI publications	Improving refrigeration efficiency and reducing electricity use New tool sheds light on relationship between grape and wine tannins Effects of oxygen exposure during pressing and juice/wine handling Authenticity issues on the rise Formation of hydrogen sulfide from cysteine in Saccharomyces cerevisiae BY4742: genome wide screen reveals a central role of the vacuole Closure trials demonstrate volatile sulfur compound formation Ask the AWRI – the power of pH
Current literature – oenology	Australian Pinot Noir Fermenting with stems: WALT winemaker takes creative approach for Pinot Noir Co-inoculation with yeast and lactic acid bacteria Audit of microbiological risks. A powerful diagnostic tool for understanding contamination problems. Example for the yeast Brettanomyces bruxellensis Best practice in managing MLF whether adopting a cultured approach or leaving it up to nature Key changes in wine aroma active compounds during bottle storage of Spanish red wines under different oxygen levels Stickiness: a new concept in grape and wine tannin In-line measurement of color and total phenolics during red wine fermentations using a light-emitting diode sensor The birth of precision bottling: audit of bottle oxygen variation in winery trials shows size of the challenge The commoditisation of Australian wine in export markets Acceptability of reduced-alcohol wine. Relative importance of taste and information
