Alcoholic beverages vary considerably in ethanol content and in foodstuffs they are produced from.
The ethanol content in alcoholic beverages can be increased by means other than distillation.
The exact reason why beverages with higher ethanol content do not stimulate acid secretion is also not known.
Sweden has a similar seasonal reduction, but the ethanol content in the blend is reduced to E75 during the winter months.
AAA said that more research needed to be done on the potential harmful effects prior to increasing the ethanol content in fuel.
An ethanol content of 31.5-32% is considered optimal for Limoncello.
The difference was 0.07 in favor of 98E5 on average, meaning that using 95E10 gasoline, which has a higher ethanol content, increases consumption by 0.7%.
The seasonal reduction of the ethanol content to an E85 winter blend is mandated to avoid cold starting problems at low temperatures.
Individual manufacturers can use their own "formulation standards" in which the ethanol content usually ranges from 70-99% v/v.
For comparison, yeast dies when the ethanol content of its feedstock hits 14%.
