A superyeast contains a) an alcohol tolerant yeaststrain, and b)
a complex nutrient with trace minerals. There are different types of
superyeasts: 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 superyeasts, like the "stackable" GoldYeast 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 superyeasts 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 superyeast but Alcotec 8 was the first major
brakethrough 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's. 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 increadible
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.
