pH
harvest - for optimum ripeness (w/ TA, Brix)
pre-frermentation - to optimize yeast fermentation
pre-MLF - to optimize growth of desired MLF bacteria
post-MLF - to determine proper sulfite additions
maturation - to determine proper sulfite additions
bottling - to prevent premature/excess aging

Titratable Acidity
harvest - for optimum ripeness (w/ pH, Brix)
post-fermentation (whites)- to adjust for proper taste balance
post-MLF (reds) - to adjust for proper taste balance
maturation - to correct for acidity losses during aging
bottling - to ensure taste balance (don't bottle right after adjustment)

Residual Sugar
fermentation - to determine completion of dry wine fermentations

L-Lactic Acid
MLF - to confirm the start of MLF

Malic Acid
pre-MLF - to estimate loss of acidity during MLF (w/ dilution of sample)
MLF - to monitor for stuck MLF
MLF - to determine completion and time to add sulfite

Free SO2
to confirm proper addition during cold soak (whites)
post-fermentation (whites) - to confirm proper addtion
post MLF (reds) - to confirm proper addition (>50% becomes bound)
maturation - to determine need for replacement due to oxidation, binding

D-Lactic Acid
must - to determine excess contamination
fermentation - to check for growth of unwanted lactic bacteria,
ooooespecially with sugar present and a stuck fermentation
MLF - to check for growth of unwanted lactic bacteria
maturation - to check for growth of unwanted lactic bacteria

WineAnalysisBlog.com Present topic is "Don't be Fooled!" Poor results with
expensive equipment or time consuming procedures are still poor results!
(Study shows over 50% of malic acid results are beyond acceptable ranges.)

PRESENT ACTIVITIES IN THE NORTHERN HEMISPHERE AND SOUTHERN HEMISPHERE

The global economic crisis is having an impact across all economic sections. In a number of markets consumers are reducing discretionary spending by drinking less or buying less expensive wine. Exacerbating this trend, in some major markets oversupply had led to price wars.

There are bright spots. While Australia has seen a decline in its export volumes, New Zealand has increased its exports to Australia, especially of Sauvignon Blanc. Changing consumer preferences may be part of the reason for the changing market fortunes. Wine exports to China have increased in both total value and unit value. And in the U.S., the wine industry is looking forward to having a wine-drinker as President, especially one with a personal 1,000-bottle cellar.

The bottom line: watch consumer trends, and manage the winemaking process with economical tools to produce the wine you want reliably and at the most competitive cost!

PRESS ROOM

ACCUVIN opens for Free Trials with Your Wines!
At Accuvin's new location, 2405 Laurel St., Suite 108, Napa, CA, on Wednesdays from 4:00 - 6:00, enjoy our "Free! You-Try Open Lab"

Mike Miller, president and creator of Accuvin's tests, will attend. "I want to visit with test users, to see how we can help streamline the manufacturing process that is winemaking. This will leave winemakers more time for the art of individual interpretations in the areas of extraction, fermentation, MLF, blending, and maturation."

All seven Accuvin tests will be provided for trials.
