Golden Quaff

[DRB]

I,ve named this beer Golden Quaff.
This is what i,m doing now.

Optic - 2430g

Torrified Wheat - 100g

Flaked Barley - 100g

Crystal - 50g

Progress - 13g start of boil
Progress - 12g last 5 min of boil

mashed at 67,
IBU - 20
Recipe for 12 litres

Worked out my mash efficiency = 87.88%

Target og 1043 for 12 litres,I managed 1045 for 10.5 litres after topping up with water.I presume the other 1.5 litres is the dead space in my boiler,so if I could have got that in,it would have been 12 litres and spot onor don't it work like that.

[DRB]

If I were to add the extra 1.5 litre to make it to 12 litres,is there any way you can determine how much it will drop the OG before adding it in.

I know that beersmith has a dilution tool. I used to use that to work out how much water I was willing to add before the OG would drop below an acceptable amount.

You basically plug in the gravity and volume of you orginal batch then you put the volume and gravity of what you are adding. This will give you the new gravity.... Nover worked out what to do if you where adding to a fermented beer though... I would only use it for adding to unfermented wort - then you can't really get it wrong!!!!

Bottled my Golden Quaff today,also added gelatine, the last few times I added it ,it went all funny and turned to jelly bits in the brew,but this time I allowed to cool until luke warm seems to have done the trick, no funny jelly bits ,anyway here's the result,looks like it compliments the name.OG 1045-FG 1008.

Keep the bottles out the sunlight DRB!

I think this would work out the dilution effects on OG by adding water to wort:


volume of water added / original volume of wort X 100 = % increase in volume

So you if added 1.5 litres to 10.5 litres it would be: 1.5L/10.5L X100 = 14.3% (increase in volume).

Now you need to decrease the O.G. by 14.3%.

1045 is the OG from 10.5L, but we are only interested in the 45…. So 45/ 100 X 14.3 = 6.4

1045 - 6.4 = 1038.6 (new gravity after water addition).

I think this works in theory, but have never tried it in practice…would be interested to know if it works
