Wine Making
This range of yeasts is intended for the production of alcohol at concentrations of up to 23%.
They each produce 5 gallons but they have different sugar requirements
They are not intended to ferment out either beers or wines but rather to produce the base for liqueurs.
The alcohol level can be further increased, in countries where this is legal, by distillation.

Alcotec Re-Start Super Yeast
£1.50
At last we have a re-start yeast sachet which contains a decent quantity of yeast, 49 grams.
If the hydrometer reading is 50-60 units below the start value (i.e. 6-8% alcohol) you must use a special restart yeast. Alcotec Re-start Superyeast will do the trick here. A normal wine kit starts at 1075-1085 so if your current reading is somewhere between 1015-1065 it is worth a try with this yeast.
Add the full contents of the sachet directly to 25 litres of wine or wash. Alternatively, make a starter of lukewarm water, sugar & a little nutrient & let this ferment for a day before introducing it to the must.
