Alcohol, Extract and Calculated Values
Designed for quality control and quality assurance, this analysis service is a great test for first time users. This service provides a wide assortment of information including alcohol by volume, and original and real extract and can be used by breweries of any size to identify critical issues within the brewing process. Alcohol by volume is an essential component of TTB label submissions and is required to control the strength of beer produced by high-gravity fermentation techniques. Utilizing alcohol content, the quantity of fermentable sugar prior to fermentation can be calculated and added to the real (or residual), an extract value which encompasses nonfermented carbohydrates, primarily dextrins, to produce the original extract value. Real extract value allows you to monitor the balance of fermentable to nonfermentable carbohydrates in the wort and whether the fermentability of the wort was too high or too low. Additionally, this service tells you the calories of your beer, if you hit the right efficiencies in your mash, and if it fermented properly by gravity values. |

Metals and Other Ions
Several inorganic ions play key roles in the brewing process, from allowing metabolic processes of the yeast to function efficiently to protein precipitation and even the undesirable oxidation of beer. Monitoring these ions periodically at multiple stages of the brewing process will allow you to produce a higher quality finished product and take preventative measures when necessary to avoid the costly experience of dumping a tank. This method measures calcium (Ca), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), and sodium (Na). Without certain ions, fermentation will not be as effective. Ultimately, this analysis helps determine if supplements are needed to ensure a more consistent, higher quality product. |

International Bitterness Units (IBUs)
International Bitterness Units measures the actual bitterness of beer. This test can be utilized to determine hopping regimes, assist with product consistency, and can help determine the utilization of your hops throughout the brewing process. IBUs can also serve as a way of troubleshooting your brewing process, validating your recipe, and ensuring hop product consistency across uniform finished products. |

$30.00 |
Color and Clarity
This quality control measure will assist you in maintaining color and clarity constancy and give you the knowledge to help prevent your beers from being cloudy or off-color. There are multiple factors which influence color and clarify of beer. For instance, alternating grain suppliers or adjunct usage can dramatically affect the color and clarity of the final product. By tracking this value, you will be able to confirm consistency from batch to batch. |

$15.00 |
pH
This analysis service determines pH at any time in the brewing process and can aid in the monitoring of fermentation performance. During fermentation, many different acids are secreted by yeast, such as citric and acetic acid, and the pH lowers. The more energetic and longer the fermentation, the lower the pH goes. pH has a considerable effect on beer quality, influencing flavor and suppression of microbial growth. Analysis at different stages of the brewing process can yield different information including protein profiles and sugar extractions at the mash stage, to hop utilization and antimicrobial properties during the boil. Craft brewers and home brewers alike will benefit from the analysis as it helps increase style consistency and identify issues with flavor contribution within the brewing process. |

Dissolved CO2, Air, and Headspace
Has your beer been excessively foamy or metallic in taste? It is possible that it is overly carbonated. Dissolved CO2, Air, and Headspace ensures that your bottling or canning process is correct, and helps ensure product consistency. Carbon dioxide is produced in conjunction with ethanol during fermentation; therefore it is a critical parameter to be specified in the finished product. If the gas level is too low, CO2 can be effervesced into the batch to meet the appropriate specification. In the event the gas level is too high, carbonation can be reduced with nitrogen sparging. Additionally, knowledge of the air and headspace will assist with monitoring bottling or canning integrity.* |

Foam Stability
By measuring the CO2 content, you can determine if the beer has sufficient capability to generate foam. However, this will not elucidate whether the resultant foam will be stable, for which this analysis is necessary. This test will provide you with confidence that your beer is true to style, with an aesthetically pleasing head for craft consumers. |

Complete Microbial Detection Package
This package combines UBA, SDA, HLP, and Wild Yeast Detection plus gram stain and identification of contaminants. A 15% savings. |
|
$140.00 |
Wild Yeast Detection Package
This package combines Lin’s Wild Yeast Medium and Lin’s Cupric Sulfate Medium analysis, providing complete wild yeast detection. A 15% savings. |

Hsu's Lactobacillus/Pediococcus Medium (HLP)
Have you had problems with sour notes in your beer? This media detects spoilage due to lactic acid bacteria. Many lactic acid bacteria can be detected in as little as 48 hours, and differentiation of Lactobacillus and Pediococcus can be made after 5 days of incubation. This test can also help identify growth niches in equipment and alert you to necessary cleaning in your brewery. |
|
$35.00 |
Lin's Cupric Sulfate Medium (LCSM)
Have your products been inconsistent? This media will detect wild yeast populations in brewing culture yeast and help prevent consumers from receiving an unintended product or flavor. This medium is formulated to encourage the growth of Saccharomyces wild yeast and helps identify true to type, or yeast purity. It is recommended that this media be analyzed in conjunction with LWYM. |
|
$40.00 |
Lin's Wild Yeast Medium (LWYM)
This media allows for detection and quantitative determination of wild yeast populations in brewing culture yeast, which can produce unintended flavors. This medium is formulated to encourage the growth of non-Saccharomyces wild yeast. It is recommended that this media be analyzed in conjunction with LCSM. |

$35.00 |
Schwartz Differential Agar (SDA)
This media detects the presence of aerobic and/or anaerobic bacteria in beer or yeast slurries. This analysis helps identify bacteria that are commonly resistant to the effects of hops, ethanol, low pH, high CO2, and a lack of oxygen. Minor contaminations of this nature can give the beer off-flavors, turbidity and ropiness. Additionally, this test identifies thermophile (heat-resistant bacteria), which can be difficult to eliminate once contamination has occurred. To prevent growth of these organisms, routine analysis must be done of the pitching yeast, wort, beer and equipment. |

$35.00 |
Universal Beer Agar (UBA)
This test will monitor your beer and yeast strains and determine if there is any contamination. The characteristics of the Universal Beer Agar (a basal medium to which beer is added) replicates the natural environmental conditions found in the typical brewery, and supports growth of more varieties of lactic acid bacteria and yields larger colonies in a shorter time than traditional brewers medium. Due to the presence of beer in the medium, it is selective for growth of microorganisms that have adapted themselves to existent conditions in the brewery. By identifying contamination, you can ensure that the quality of your product will be consistent from the brewery to the consumer. |
