| A super yeast contains a) an alcohol
tolerant yeast strain, and b) a complex nutrient with trace
minerals. There are different types of super yeasts: high alcohol
ones, fast ones, VERY fast ones (Alcotec 24, the only 24-hour turbo
in the world) etc. We produce all types |
| |
|
3-day fermentation - Normal Alcohol (14%)
|
|
 |
|
Alcotec 6 Turbo Yeast
(or just Alcotec - the "6" means it ferments 6 kgs of sugar
in 25 litres) is the best example of this type. It will
ferment 14% of alcohol in 3 days. It performs best in 25
litres but you can increase the volume somewhat (i.e.2
sachets and 50 litres). Larger volumes are possible but best
with temperature control (cooling equipment). Without
cooling of large batches fermentation will stick too soon at
a low alcohol level.
Fermentation is over at
s.g. 985 (approximately). Don't make the common mistake and
assume that s.g. 1000 (0 on some hydrometers) means finished
- there will be 2% more alcohol still to come! Always check
s.g. and if fermentation sticks too high, there is probably
a temperature problem. Have a look in our turbo yeast tips
section for troubleshooting.
We also produce some
speciality super yeasts, like the "stackable" Gold Yeast 200
(currently only for the Scandinavian market) which will work
well without cooling in batches up to 200 litres and can
handle up to 600 litres without cooling but with some
performance loss (but other super yeasts would cave in
totally here).

High Alcohol (18-20%)
|
 |
Alcotec
8 (ferments 8 kgs of sugar in 25 litres)is the best example. It
is very difficult to make a high alcohol super yeast but
Alcotec 8 was the first major
brake-through in the world. In only 5 days, it will produce nearly
20% of alcohol from 8 kgs of sugar in 25 litres total volume.
The drawback with a high
alcohol turbo is that it is more temperature sensitive than the "low
alcohol" type. You MUST keep the liquid temperature below 24-25 C at
all times or your fermentation will stick too high.
The amazing
Alcotec 48 is the next generation of
high alcohol Turbo. It is a "dual" turbo, you can choose if you want
to ferment 14% alcohol in 2 days or 20% in 5 days and it is also
much more temperature tolerant than the
Alcotec 8. This turbo was launched in 2003.

The 24-hour Turbo
|
| We developed and produced
the worlds first 24-hour turbo in 1999. This is the Willes 24, sold
on the Scandinavian market. This is an incredible breakthrough in
fermentation technology - it really produces some 12-13% alcohol in
24 hours. You have never seen a fermentation like this before, it's
more like an alcohol explosion. The
Alcotec 24 was launched in 2002 and is
now one of the leading superyeasts in the world with exports to a
large number of countries. |
