Miscellaneous

Name	Type	Use	Amount	Time [Minutes]
5.2 buffer	wateragent	mash	6.90 (0.24) [gms (oz)]	(Not Available)
Sulphate	wateragent	boil	4.93 (0.17) [gms (oz)]	(Not Available)
Whirfloc	wateragent	boil	0.00 (0.00) [ltr (gal)]	10.0

Estimated required yeast cells (billion):

188.32

Dried yeast (gm):	10.02

No of liquid yeast(Wyeast/Whitelabs) packs:	2.00	(Assumes 94% viability)

Approximate amount of solid slurry (ml):
One hour settling	267.11	(Assumes 25% trub and 94% viability)
One day settling	133.56	(Assumes 25% trub and 94% viability)
Longer than 1 week settling	69.75	(Assumes 25% trub and 80% viability)

Note yeast viability reduces greatly over time as demonstrated in the table below.

Age	Viability	Age	Viability
1 week	80%	2 weeks	70%
3 weeks	60%	4 weeks	50%
5 weeks	40%	6 weeks	25%
7 weeks	15%	8 weeks or older	less than 10%

Viability deterioration varies greatly between different yeast strains. You should consider doing a yeast starter for any yeast older than 2 weeks to ensure yeast viability prior to pitching.

Liquor to grist ratio [ltr/kg]:

Saccrification rest - 3.00 to 4.00 [ltr/kg] is recommended.

A lower liquor to grist ratio will produce a less fermentable wort (with more complex sugars) while a higher liquor to grist ratio can result in a more fermentable wort.

Both extremes will require a longer rest time ( up to 90 minutes )

Protein rest - less then 2.50 [ltr/kg] is recommended.
