Why Sourdough and Guinness Make the Perfect Pair
The deep, roasted notes of Guinness beer complement the tangy depth of sourdough, creating a bread that’s moist, rich, and bursting with flavour. The natural carbonation in Guinness also gives the dough an extra lift, resulting in a soft, airy crumb and a dark, caramelised crust. Whether paired with a hearty stew or enjoyed on its own with butter, this bread is guaranteed to impress.
Ingredients You’ll Need
Here’s what you’ll need to bake your own Sourdough Guinness Bread:
- 200g active sourdough starter (bubbly and ready to use)
- 500g bread flour
- 100g whole wheat flour
- 330ml Guinness beer (one standard bottle)
- 100ml water (adjust as needed for dough consistency)
- 10g salt
- Optional: 1 tbsp honey or molasses for a touch of sweetness
Step-by-Step Guide to Sourdough Guinness Bread
1. Activate Your Starter
Before you begin, ensure your sourdough starter is active and bubbly. Feed it a few hours ahead of time so it’s at its peak.
2. Mix the Dough
In a large mixing bowl, combine the bread flour, whole wheat flour, and salt. Slowly add the Guinness, water, and sourdough starter. Mix until a rough dough forms. Add honey or molasses if desired for a slightly sweet and malty flavour.
3. Autolyse (Rest the Dough)
Cover the bowl with a damp towel and let the dough rest for 30 minutes. This allows the flour to fully hydrate and makes the dough easier to work with.
4. Stretch and Fold
Perform 3-4 rounds of stretch and folds every 30 minutes over a 2-hour period. This step strengthens the dough and builds structure.
5. Bulk Fermentation
Cover the dough and let it ferment at room temperature for 4-6 hours, or until it doubles in size. Alternatively, you can place it in the fridge for an overnight rise (8-12 hours).
6. Shape the Dough
Turn the dough onto a floured surface and shape it into a round or oval loaf. Place it seam-side up into a floured banneton or proofing basket.
7. Final Proof
Let the dough proof for another 1-2 hours at room temperature, or until it passes the “poke test” (the dough springs back slowly when gently poked).
8. Bake the Bread
- Preheat your oven to 230°C (450°F) with a Dutch oven inside.
- Carefully transfer the dough onto parchment paper, then place it into the hot Dutch oven.
- Score the top of the loaf with a sharp blade for a professional finish.
- Bake with the lid on for 20 minutes, then remove the lid and bake for another 20-25 minutes, or until the crust is deep brown and caramelised.
9. Cool and Enjoy
Allow the bread to cool completely on a wire rack before slicing. This helps the crumb set and prevents it from becoming gummy.
Tips for Perfect Sourdough Guinness Bread
- Use Cold Guinness: Chilled beer slows fermentation slightly, giving your dough more time to develop flavour.
- Experiment with Add-Ins: Add shredded cheddar, chopped walnuts, or caramelised onions for a gourmet twist.
- Store Properly: Keep your bread in a paper bag or bread box to maintain its crusty exterior.
