Notes

Lightbulb is a modern pale ale full of bright hop flavours and mind sweetness that rounds out the whole beer and makes it more substantial. At only 4.5% this beer would give most 7% IPAs a run for their money.

Yeast: Use half pack of S-04 and US05
Fermentation temperature/steps: Ferment at 18, then diacetyl rest at 22c.

If using oats with husks the quantity of oats will need to be adjusted to account for the husks (e.g. use 1.5kg oats with husks if the ratio is 50/50).
