Irish Guinness Wheaten Recipe
The Irish Guinness Wheaten is a dense, moist brown bread made from coarse wholemeal flour, oats, and Guinness stout. Its texture is hearty with a slightly sweet undertone from the treacle and brown sugar. The combination of baking soda and stout gives it a tender crumb and a subtle tang, making it a distinctive alternative to traditional soda bread. It's baked in a loaf pan with oats sprinkled on top and finishes with a crisp, hollow-sounding crust when done.

Notes
- Use a digital kitchen scale for accurate measurements to ensure consistent loaf texture and rise.
- Treacle or molasses can be used interchangeably; in some regions, Zuckerrübersirup is a suitable alternative.
- Opt for coarse or stoneground wholemeal flour to replicate the traditional texture closely.
- Choose old-fashioned rolled oats or porridge oats, avoiding steel-cut oats, for the best crumb and topping effect.
- When substituting Guinness stout due to quantity constraints, replace the missing volume with buttermilk or yogurt to maintain proper acidity and moisture.
- Guinness may be substituted with another type of stout beer if unavailable.
