Alcohol Measurement

Are you measuring your alcohol?

 

TTB Certified LabIf you brew kombucha, beer, cider, or spirits, you need to know the alcohol content of your beverages for two reasons:

1) To understand your legal requirements

  • Do you fall under the jurisdiction of the TTB with your beverage?
  • Do you have special label requirements based on your alcohol content?
  • Do you need to pay any specific taxes related to your alcohol content?

2). To inform the consumer of the alcohol content of the beverages you produce. Wouldn’t you want to know?

 

So, what does this all mean for you?

Beer & Cider

Brewers, we have been offering alcohol measurements since our doors opened in 2016. Kathinka Labs is a TTB certified lab for alcohol measurement of beer. We offer several packages, such as the BrewTTB, Brew¹, and Brew², that include alcohol analysis, based on the Anton Paar Alcolyzer. Distillation is also available for higher alcohol beers.

Cider makers, we have the same alcohol measurement packages available for you under Cider¹ and Cider².

 


Kombucha

Kombucha makers, we have several options to help you analyze your alcohol content. We offer the Kombucha¹ and Kombucha² packages, also based on the Anton Paar Alcolyzer. We can add distillation to these packages as well. We also offer the Kombucha4 , which is the AOAC method using GC-FID.

kombucha alcohol analysisWhy do I need to measure alcohol in kombucha?

Alcohol by Volume (ABV) is a standard measure of how much alcohol (ethanol) is contained in a given volume of an alcoholic beverage (expressed as a percent by volume). During the fermentation process, alcohol is created in your kombucha. We believe it is important that you and your consumers know and understand the alcohol content of your well crafted beverage. Transparency is important so that consumers can make well-informed decisions about what they buy and drink.

Alcohol levels are also regulated by federal laws, and at this point in time, kombucha must be below 0.5% ABV to be considered a non-alcohol beverage by the TTB.

 


Spirits

Or, maybe you are a distiller making spirits (an alcoholic beverage produced from the distillation of a mash made from grains, fruits, or other substrates that has undergone an alcoholic fermentation).  We offer several alcohol measurement packages for a variety of spirits.

Depending on the make-up of the spirit, there are three different methods that are followed. For example, a clear spirit (i.e. vodka) is low in solids and therefor can be measured as-is. A whiskey, on the other hand, has more dissolved solids and obscuration must be accounted for in order to obtain the true proof of the spirit. Lastly, high solids spirits (i.e. flavored liqueurs) must be distilled on the lab scale before measurement to obtain the true proof.

Spirit makers, these are your options for measuring alcohol:

1) Clear Spirit Method (CSM): This lab analysis package is our basic package for those distillers that would like an accurate reading of their distilled spirit’s proof. The sample, such as a vodka or gin, is ready to measure directly using a precision densitometer.

2) Obscuration Method (OBM): This lab analysis package is our package for those distillers with spirits that have some dissolved solids, such as barrel-aged spirits or other whiskey products, and would like an accurate reading of their distilled spirit’s proof. The sample is processed by separating solids from the alcohol via evaporation in order to determine the proof obscuration, and is then used to determine the True Proof of the spirit using a precision densitometer. We follow the method outlined by the TTB.

3). Distillation Method (LDM): This lab analysis package is our package for those distillers with spirits that have high dissolved solids, such as flavored liqueurs or other sweetened products, and would like an accurate reading of their distilled spirit’s proof. The sample is processed by separating solids from the alcohol via lab scale distillation, and then the True Proof of the spirit can be determined using a precision densitometer. We follow the method outlined by the TTB.

For spirits, we follow the AOAC and TTB procedures. We measure and proof spirits through densitometry using a precision densitometer. Following analysis, we post the data to your account, maintaining confidentiality and creating easy access to data for you and your staff.
