Yeast Services

Yeast Propagation

Pitchable quantities of pure yeast, bacteria and blends from 5 gal homebrew to 15 BBL direct pitches (view our Yeast Shop page for the full strain list).

Yeast Banking

Isolation and storage of proprietary yeast and bacteria strains. Includes testing for cell viability, removing from contaminating wild yeast, mold, and bacteria, petite mutant testing, freezing and storage at -80 C.

Wild Yeast Isolation

Native yeast isolated from any number of environments. Includes fermentation profile, viability, generation stability and cold storage. We will work with you to make sure the strain gives the flavor profile you want.

Analytical Services (Coming Soon)

Yeast Viability

Live/Dead staining, anaerobic respiration, cell division

Free Amino Nitrogen (FAN)

Tests for lack of nitrogen for healthy fermentation.

Bitterness Units (IBU)

Measures real amount of IBU by spectrophotometric assay.


You guessed it, a test for pH. Or more specifically hydrogen ion concentration.

Sediment Analysis

Can give indications for haze or sediment. Staining and centrifugation investigating suspended yeast, protein, lipids.

Alcohol Content

Alcohol content by weight and volume.

Nutrition Analysis

Nutrient figures for each beer for total fat, calories from fat, saturated fat, trans fat, cholesterol, sodium, total carbohydrates, dietary fiber, sugar and protein.

Water/Wort Analysis

Test includes pH, TDS, sodium, potassium, calcium, magnesium, total hardness, nitrate, sulfate, chloride, bicarbonate, total alkalinity, total phosphorus, total iron.

Contamination Testing

Your choice of WLD, HLP, SDA, LCSM media testing (~5 days) or PCR analysis for quicker turnaround and identification. These tests can be done by swab on equipment or in liquid at any stage of the process.

Mixed Culture Isolation

Isolation and identification of mixed suspensions by plating and genetic testing.

Total Acidity

% Lactic Acid by Titration

SRM Color

Test by spectrophotometer.
