I grabbed my bottle of OF 100 to compare w the 1920. 100 is definitely out classed. They both have that yeasty sweetness on the nose. 100 has more ethanol youth and a tiny banana. 1920 comes in stronger w more depth on the nose with some spicey citrus. The taste really sets them apart. 100 is lighter and younger with less spice. 1920 has that deep rich tangy spice. A cinnamon fruit numb finish. The only thing the 100 got going for it is the $20 price tag. 1920 costs over $60 where I am. I think 1920 is only about twice as good for 3 times the price. Probably worth it for me but maybe not for everyone.
