Individual Analysis Analysis
PREPARING AND SENDING SAMPLES 1. In order to ensure the most accurate analysis, please send full (topped) containers of beer optimally packaged for shipping to minimize breakage. 2. Download and submit a completed Analysis Request Form with your samples. A form can be obtained by scanning the QR code on this page or by calling 707.224.7903. 3. If specific label information is required on the report, please make sure that this information is supplied on the sample request. 4. Samples may be sent via UPS or FedEx. The US Postal Service does not accept alcohol for shipping. Samples may also be dropped off in person.

Extract produced is found by accurately determining the volume and the “gravity” of the wort collected in the starting tub, Potential extract is the sum of the products obtained by multiplying the weights of malt and adjuncts by their respective laboratory “as is” yields (fine grind yield for malt).

Example: How many bbls of beer of 3.8% and 3.2% by weight of alcohol, respectively, must be blended in order to obtain 650 bbls of beer of 3.6% alcohol? Let X = number of bbls of 3.8% beer. Then (650 – X ) = number of bbls of 3.2% beer. Substituting in formula: X x 3.8 + (650 - X ) x 3.2 = 650 x 3.6 0.6 X = 260 X = 433 Answer: Mix 433 bbls of 3.8% beer with 217 bbls of 3.2% beer.
