    Shared aroma: 2-nonenal (fatty, green).

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

What each ingredient does

White sugar
Provides the sugar that the yeast ferments into carbonation and alcohol.
Yeast
Ferments the sugar, producing carbon dioxide that makes the beer fizzy.
Lemon juice
Adds acidity that brightens the flavour of the spruce beer.

The step that matters

Bottle the mixture for storage, especially in warm weather.. Yeast is still fermenting, so carbon dioxide keeps building inside sealed bottles. In warm weather fermentation runs faster, raising the risk of bottles over-pressurising and bursting.
