 Is there any reason an IPA beer would be bad or not work for a beer bread dough?  Does it take longer, the same or short than a typical beer bread to rise?  
Different sugars have different relative sweetness (in %) (Elmhurst College):   Sucrose: 100 Fructose: 140 High fructose corn syrup (HFCS): 120-160 Glucose: 70-80 Lactose: 20   Relative sweetness of some non-sugar sweeteners (NutrientsReview):   Aspartame: 180 Acesulfam potassium: 200 (in some diet colas) Stevia: 300 Saccharin: 400 Sucralose: 600   Plain yogurt (100 g) contains 4.7 g sugars, but mostly lactose, which is not sweet. (NutritionData, milk composition)  Kirkland Protein Bars contains stevia (300% sweetness) (link - read at the bottom of the Nutrition Facts), which explains its sweetness. Stevia is a natural non-sugar sweetener.  Perceived sweetness can increase with the food temperature (ScienceDirect) and salt content (a study in mice). Liquid and solid foods with the same sugar content can have different perceived sweetness (ScienceDirect). And there are sweet taste enhancers...(ChemistryWorld)
