LMDA Plates (30pk)

The best bacteria and wild yeast test around. This agar test may be used aerobically or anaerobically to determine whether brewing bacteria or wild yeast are present and allows for quick and easy genus identification. It supports the growth of the most common types of brewing bacteria and wild yeast but suppresses the growth of most brewing yeast. 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. Keep sealed & refrigerated; 30-day shelf life.

These plates contain 7ppm cycloheximide. Click here for the SDS.

Wort Agar Plates (30pk)

30 Sterile Pre-Poured Plates

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 of up to 30 days.

Clean & Feed Yeast Care Kit

Why hose that perfectly good yeast down the drain just because the next brew day is too far out?  This unique product allows you to prepare yeast for 1 week of storage in 30 minutes flat.

Using pre-measured quantities of sterile cleaning and feeding solutions, this simple, 2-step process allows you to “clean” the slurry with activated chlorine dioxide to kill any bacteria present, and to “feed” the yeast with sterile, concentrated wort.

Then, simply store the slurry at 34°F/1°C, until needed, for up to 1 week.  The Clean and Feed Yeast Care Kit can be used for up to two weeks.  Treats the quantity of yeast cropped from a 10bbl batch.

Kit contains StarXene. Click here for SDS.
