LMDA (brewing bacteria) - $5 per tube
The best bacteria test around. This agar test may be used aerobically or anaerobically to determine whether or not brewing bacteria are present, and allows for quick and easy genus identification. It supports the growth of the most common types of brewing bacteria, but suppresses the growth of most brewing and wild yeasts. If individual colonies arise, note the color, texture and size of each type. Also, note whether any colonies have changed the color or cloudiness of the media immediately surrounding them. After running a gram-stain, compare your observations against the characteristics listed for each genus, and identification is complete. Click here for an identification key. Keep refrigerated; shelf life is indefinite.  

LCSM (rare wild yeasts) - $5 per tube
This aerobic agar test reveals the presence of non-Saccharomyces (of a genus other than that of brewing yeast)
wild yeast, but does not allow for further identification. If distinct colonies appear ("mountains" as opposed to "mole-hills"), wild yeast is present. Click here for help interpreting results. Wild yeasts are not usually tolerated at any level, because they are as unaffected by acid- washing, low pH or alcohol content as brewing yeast, and so their numbers may increase with every pitch. Keep refrigerated; shelf life is 1 week.

LWYM (common wild yeasts) - $5 per tube
This aerobic agar test reveals the presence of Saccharomyces (of the same genus as that of brewing yeast)
wild yeast.  If distinct colonies appear ("mountains" as opposed to "mole-hills"), wild yeast is present. Click here for help interpreting results. Wild yeasts are not usually tolerated at any level, because they are as unaffected by acid-washing, low pH or alcohol content as brewing yeast, and so their numbers may increase with every pitch. Keep refrigerated; shelf life is 1 week.

RDMA (petite mutants) - $5 per tube
A BSI-exclusive! This aerobic agar test reveals the presence of respiratory-deficient mutants without the need for messy overlays. Normal yeast colonies will appear pink or red; mutant colonies will appear white. According to George Fix, a mutant population of about 1% is considered normal and acceptable, but flavor is affected when they constitute more than 5% of the total. Keep refrigerated; shelf life is indefinite until media turns pink.

WORT (brewing yeast) - $5 per tube
This aerobic nutrient agar is designed for the growth, storage and conditioning of yeast cultures. Because it is made from wort, it presents yeast with a nutrient profile similar to what the yeast will encounter when pitched, and so may be said to "condition" the yeast in a way that YPD and other nutrient agars cannot. Yields are comparable to commercial nutrient agars. Keep refrigerated; shelf life is indefinite.
