Why Stout ages this way

Stouts derive character from heavily roasted malt — chocolate, coffee, slight burn. These compounds are exceptionally stable, often improving slightly in the first 3-6 months as harsh roast notes mellow. The thick body and high mouthfeel also resist oxidation better than thin-bodied beers.

How to store Stout

Cool storage works fine for a year or more. Refrigeration isn't necessary unless you're holding for multiple years.

When to drink it

Within 12 months for peak character. Many dry stouts and oatmeal stouts drink well at 18 months. Past 2 years, expect malt fade unless it's a high-ABV imperial.

Worth knowingGuinness famously contains a small amount of nitrogen, not just CO2, giving its iconic creamy mouthfeel and tight head.
