A FEW WORD ABOUT YEAST NUTRIENT

One of the nutrients naturally lacking in most wines is nitrogen. Having

sufficient nitrogen in the fermentation allows yeast to reproduce more

readily. The higher the rate of reproduction, the higher the wine’s rate

of fermentation. Nitrogen also helps the yeast to produce higher levels

of natural enzymes, which means your wine will clear and age quicker.

Having plenty of nitrogen will also increase the yeast’s tolerance to

alcohol.

The most common source of nitrogen is Yeast Nutrient it comes either in

powder or tablet form. Yeast Nutrient supplies nitrogen to the yeast in

the singular form of a phosphate. Yeast Nutrient is sufficient for make

wines from grapes and other fruits that are similar to grapes such as

currants and berries.

In certain situations Yeast Energizer may be more beneficial than Yeast

Nutrient. Just like Yeast Nutrient, the Energizer supplies the wine yeast

with much needed nitrogen, but from a wider range of nutrients than just

phosphate. Yeast Energizer contains over a dozen yeast extractive

proteins, along with B1 Vitamin, and di-ammonium phosphate. All are

valuable sources of nitrogen.

Yeast Energizer should be used when fermenting certain types of wines

such as meads, vegetables, herbs, etc. The more the produce is unlike

grapes, the more likely Energizer will be of benefit. Unlike grapes, these

type of musts are typically deficient in the set of nutrients wine yeast are

used to receiving. Yeast Energizer compensates for these deficiencies.

Another essential nutrient that aids the fermentation process is lipid.

Lipid is what makes up the outer wall of the yeast cell. Every time a yeast

cell reproduces itself (budding), a single yeast cell is split in half to form

two cells. During the budding process the amount of lipid available for

each cell is cut by half. So as available lipid is decreased through each

generation of budding, the ability of a yeast cell to reproduce itself

diminishes.

Ghostex is a product we offer that is designed to replenish the supply of

lipid to the yeast during its reproductive stage. This will help to eliminate

a sluggish fermentation later on. Ghostex also causes the yeast to

remain suspended longer. This will be a beneficial factor later in the

fermentation as alcohol levels rise and sugar levels fall.
