Colour: 23.3 SRM
BU:GU: 0.51

ABV	OG	FG	IBU	SRM	BU:GU
7.5%	1.079	1.021	40 IBU	23.3 SRM	0.51

How are these worked out?

See which recipe values were used and why a figure may be incomplete.

OG — Calculated

Estimates original gravity from the recipe fermentables, their potential or yield, applicable brewhouse efficiency, and final batch volume.

Values used

Batch volume: 23 l
Brewhouse efficiency: 80%
Fermentables saved: 5

How it’s worked out

Estimated from fermentable source data and batch volume.

FG — Calculated

Estimates final gravity from the calculated OG and the first usable saved yeast attenuation.

Values used

Calculated OG: 1.079
First usable yeast attenuation: 73%
Yeast entries saved: 1

How it’s worked out

Estimated from OG preview and first available yeast attenuation.

ABV — Calculated

Estimates alcohol by volume from the calculated OG and FG.

Values used

Calculated OG: 1.079
Calculated FG: 1.021

How it’s worked out

Calculated as (OG - FG) × 131.25.

IBU — Calculated

Estimates bitterness with YouBrew’s Tinseth calculation using saved boil or first-wort hop data, wort gravity, volume, and equipment hop utilisation.

Values used

Batch volume: 23 l
Boil volume: 28 l
Equipment hop utilisation: 100 %
Hop additions saved: 2

How it’s worked out

Tinseth estimate using average boil gravity, final batch volume, and stored boil hop additions.

Colour / SRM — Calculated

Estimates beer colour from fermentable amount and colour together with final batch volume.

Values used

Batch volume: 23 l
Fermentables saved: 5

How it’s worked out

Morey-style estimate using stored fermentable colours.

BU:GU — Calculated

Compares calculated bitterness with calculated original-gravity points to show the bitterness-to-gravity balance.

Values used

Calculated OG: 1.079
Calculated IBU: 40 IBU

How it’s worked out

Calculated from YouBrew IBU and OG previews only.
