Roast Barley is the signature grain of a dry Irish stout. This 1kg bag gives you enough for the dark, coffee-like roast in most 23 litre stout and porter recipes.

What it does

Roast barley is unmalted barley roasted to a dark, dry finish. It delivers sharp, coffee-like roast, a dry bitterness and a deep reddish-black colour - rounder and more coffee-forward than black malt. A modest percentage is all most recipes need.

Frequently Asked Questions
What is the difference between roast barley and black malt?

Roast barley is unmalted barley roasted dark. It gives a rounder, coffee-forward roast, while black malt tends towards a sharper, more ashy edge.

How much roast barley goes in a stout?

Typically 3-10% of the grain bill. Higher amounts give a drier, more roasty stout.

Can I steep it for a kit or extract beer?

Yes. Roasted grains do not need converting, so roast barley can be steeped in hot water to add colour and roast to a kit or extract brew.

How should I store it?

Keep it sealed in a cool, dry place to keep the roast flavour fresh.
