Philosophy of change

• “ A corporation is a living organism; it has to continue to shed its skin. Methods have to change. Focus has to change. Values have to change. The sum total of those changes is transformation” Andy Grove, Intel

20 years of advancement? •

Over the last 20 years science has advanced our understanding of wine. There are at least 2 areas that have contributed significantly to the improvement of quality:

– Post bottling wine chemistry & wine bottle closures. – Corks, screwcaps, closures etc

– Understanding the role of oxygen in wine. – Reductive winemaking, TPO, micro oxygenation etc The common denominator is OXYGEN. “Exposure of wines to excessive amounts of oxygen causes irreparable damage, leading to the production of off-flavours associated with aldehydes and bacterial spoilage” Tofalo et al,2012. “Wine specifications should be moving to detail TPO instead of the less relevant DO; and in regard to TPO, generally the lower the better” Roget, AWRI

Oxygen Management is why inert gas is used; has the technology advanced? Sources: Jamie Goode, “What have scientists done for us” & Internet Journal of Oenology & Viticulture,2102 N.7/1

Transforming quality; Targeting TPO to add value Gather the facts; (assess & audit equipment & operations )

Define realistic objectives

Add in control & technology options (repeatability)

Examine opportunities with research & knowledge

Add in appropriate & on-going training

Identify & eliminate bad habits (inefficiency)

Focus on Winemaking Up to $1.50/bottle is winemaking & may be gas related

Typical gassing operations (gas + labour) account for up to 30% of this (~$0.50/bottle)

A 20% efficiency improvement in this area alone will increase the profit by ~$0.10/bottle

Attention to ullage management techniques can (a) improve the TPO (b) further reduce production costs by reducing top up operations (typically ~8/yr)

Two recent assessments have shown a 25% - 60% improvement (>$150,000 in one case)

Gaseous Oxygen %

To manage dissolved oxygen, gaseous oxygen levels (i.e.the tank ullage) need firstly to be managed (TPO). Example 1: DO level = 0.5mg/l, @ 10C, ullage O2 needs to be 3 times more expensive than CO2 Bulk & almost 6 times more expensive than a generator, but there are occasions when its use is justified.

• 6-8 bar • 99.5 – 99.9% • SE ~0.9kw/m3 • Smaller compressor, some pressure drop

• 10-12 bar • 99.5% • SE ~1.0kw/m3 • Higher pressure, lower pressure drop

• 6-8 bar • 99.9997% • SE 0.36kw/m3 • Very high purity = low DO. • Some LIN req’d

Comments: • PSA technology is older • Mtc issues with some PSA’s • Potential noise issue with PSA’s • Membranes performance degrades in the 1st year & need to be quoted accordingly. • Decision needs to be made early regarding a fully maintained unit (rent) or a “do it yourself” (buy). • Look to upgrade potential 13  Don Allen; trading as “Gas with Panache”, 2012
