HOW TO INCREASE THE ALCOHOL CONTENT OF THE
STANDARD KITS
To increase the alcohol content you need to add more
extract or sugar to the wort made up to 23 Litres (5 UK
Gallons/6 US Gallons).
For beers it is better to add liquid or dry extract made from
barley but a certain amount of dextrose (glucose) sugar is
acceptable as long as it isn’t more than 20% of the total
ingredients in terms of extract added (liquid malt extract is
80% extract, dry malt extract is about 98% extract and sugar is
100%). Too much sugar makes for a bad flavour for beers.
NOTE: German brewmasters will never add sugar as an
ingredient in beer due to the famous German Beer Purity Law
from 1516 known as the Reinheitsgebot. So only add DME if
you’re making a German style beer and want to increase the
alcohol. Check the BJCP Guidelines as highlighted in Appendix
10 for details on what ingredients are allowed for what beverage
style.
Fruit beverages such as cider, mead and sparkling wines can
handle a higher addition of sugar to boost alcohol or cheapen
the total ingredient cost but the yeast will need a yeast nutrient
added to the must as supplied with our cider kit.
If we assume dry malt extract/sugar is added to a Standard
WilliamsWarn Kit, the approximate increase in initial SG is
shown in the table below. If we assume a resulting final SG of
1.010, the different alcohol %’s can be seen also.

In reality, the higher you go in initial SG, the more alcohol is
produced, but this also has an effect on the yeast and it will
not be the case that a final SG of 1.010 is reached for every
yeast type.
As higher alcohol levels are produced, some yeast will likely
not ferment all the way down and the final SG will finish a bit
higher, but the table serves to show how you can increase the
final % ABV by adding more ingredients to the same 23 Litre
final volume in a WilliamsWarn.
Very roughly, for every 500 grams (17.6 oz) of DME or sugar
to a 23 Litre batch, you will increase the final alcohol by
approximately 1% ABV.
We use approximate final SG estimation for our formulas for ales
and lagers. For ales, we estimate the final SG to be the initial
SG divided by 4 or for lagers to be initial SG divided by 5. So
for a 1.060 beer, we'd estimate the ale yeast to ferment to near
60/4 = 15, so 1.015, and a lager yeast 60/5 = 12, so 1.012.
This is a rough guide and the final result will actually depend on
many variables.
