Volatile Acidity (VA)

Supplies

• We supply 50 mL centrifuge tubes and labels upon request. 

Sample

• Sample your wine in a way that is most representative of the entire lot (i.e. practice flushing your sample valve, collecting after movements like pumpovers, stirring your barrel, etc.).

Label

• Label each sample appropriately with your Client ID, Sample Date, and Sample ID. Samples for Phenolics analysis also require a Crush Date, Varietal, and Appellation. The analysis cannot be performed without the applicable information for each sample.
• Mark the sample type. ”Juice” applies to grapes and juice samples before fermentation. ”Must” applies to samples undergoing primary fermentation. ”Wine” applies to samples after fermentation.
• Select “Standard” for our corresponding juice, must, and wine panels, or select “Phenolics” for our phenolics panel. SO2 analysis can be included with the standard panel by selecting “with SO2”. Individual parameters can be added at the bottom of the label. A full list can be found on our ANALYSES page. 

Clients are able to submit samples by scheduling a pickup, delivering directly to our lab, or via the mail.

To arrange for pickup, clients must be located near Lompoc, Buellton, Santa Ynez, Goleta, or Santa Barbara and notify us by 11 am for same-day retrieval. Established clients can also use our quick scheduling function by clicking the “LAB CLIENTS” tab on the bottom right hand corner of the screen.

To ensure their stability, we ask our clients either freeze or boil their juice / fermenting wine samples before shipment. Please note that boiling or freezing your samples may influence your results and we cannot guarantee their validity. Please contact Bound with any additional questions about sample preparation before shipment. We recommend expedited same-day to one-day shipping with a tracking number included. 

Frozen 

Samples can be placed in a freezer 24-hours in advance and shipped with an ice pack. Do not over-fill the polypropylene tubes or use glass containers as the frozen liquid will expand and could pose a safety concern. Freezing samples is a better alternative to boiling when analyzing compounds like ethanol, volatile acidity, free sulfur, and phenolics. Label each sample as "FROZEN".

Boiled

We generally do not recommend boiling your samples as it can significantly alter the chemistry of your sample. If necessary, samples can be boiled in their 50 mL polypropylene centrifuge tubes with a loosely fitted cap on top. Polypropylene tubes can be boiled up to 10 minutes, but be sure not to over boil as exposure to high temperatures can change your results. Label each sample as "BOILED".
