Triticale grains and brewers’ spent grain (BSG) offer promising, sustainable ingredients for bread development, as triticale adapts well to climate change and BSG is a low-cost by-product supporting zero-waste goals. This study evaluated the rheological properties of dough and bread quality obtained from seven triticale cultivars (Ingen 35, Ingen 93, Ingen 40, Ingen 33, Ingen 54, Costel, and Fanica) grown in the Republic of Moldova, with the addition of 5% and 10% fermented dark BSG (BSGF). BSGF incorporation decreased dough stability and protein network strength, as indicated by Mixolab parameters, while the pasting properties varied according to the cultivar. Dynamic rheology showed reductions in storage (G′) and loss (G″) moduli, with tan δ < 1 for all samples. Increasing BSGF levels reduced falling number, Alveograph tenacity, extensibility, baking strength, and Rheofermentometer parameters. In bread, BSGF addition decreased loaf volume and porosity while significantly increasing acidity. Color analysis showed reduced lightness (L*) and increased redness (a*). Texture profile analysis indicated increased hardness and adhesiveness, with stable cohesiveness and reduced resilience. Sensory evaluation revealed improved color and a “hearty” texture at 5% inclusion, whereas 10% resulted in a denser structure and lower acceptability. BSGF significantly influenced the rheological, physicochemical, and sensory properties of triticale bread, highlighting the need for formulation optimization.
