Duonos gira

Bring the water to a boil in a large pot, then remove from heat and allow it to cool to lukewarm, approximately 80–90°F (27–32°C).

If using dried or stale rye bread, slice it into thick pieces and toast in the oven at 375°F (190°C) until deeply browned but not burnt, to develop a rich, malty flavor base.

Place the toasted bread pieces (or raisins if using the simplified version) into a large clean fermentation vessel or jar, then pour the lukewarm water over them.

Dissolve the yeast in a small amount of the lukewarm water, let it activate for 5–10 minutes until foamy, then add it to the main vessel along with the raisins.

Stir the mixture gently to combine all ingredients, then cover the vessel loosely with a clean cloth or lid to allow gases to escape during fermentation.

Allow the mixture to ferment at room temperature for 24–48 hours, stirring once or twice during this period, until the liquid becomes lightly effervescent and tangy.

Strain the gira through a fine mesh sieve or cheesecloth into clean bottles or a pitcher, discarding the solids.

Seal the bottles and refrigerate the gira for at least 2–4 hours before serving chilled to halt further fermentation and improve flavor.
