I grabbed my bottle of OF 100 to compare w the 1920 I just bought. 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 and light cereal finish. 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. I have ranked 100 higher in the past but its hard to keep the "value" score I gave it last time.
