Dumped 10-15 oz of trub (by weight). Gravity Reading: 1.029-1.031 sg
    Aroma: Moderate hop aroma mixed with strong alchohol presence
Appearance: poured clear. Little to no yeast in solution but still has floating particles.
Orange copper in color
Flavor: begins with moderate hop flavor that intensifies to strong bitter, followed by a
sweethop flavor and mild bitter finish. ALchohol is apparent but not overpowering.
Mouthfeel: mild weight, not to syrupy, but could benifit from a little carbonation
Impression: Flavor significantly increased when servered at 45 versus 32. Decent
continuous hop flavor with mixed flavor and bitter. Presence of sugar but not too much.
