Ttb obscuration
WebJun 8, 2024 · This means your original proof is your recorded plus the proof of obscuration. If anyone can explain the TTB version I would appreciate it. Was my original way of thinking correct or not? I don't understand why one would stop at 96% yield in the TTB's example as you would be leaving both sugars and alcohol in the lab still. Web• Obscuration is an empirical factor. It has been determined experimentally that 100 mg of solids in 100 mL of sample will obscure (lower) the apparent proof by 0.4o proof. • Obscuration = [(Wt. dish + residue) – tare] X 400 Sample size • True Proof = …
Ttb obscuration
Did you know?
WebThis obscuration is because alcohol is less dense than water but sugar is more dense than water. Adding sugar increases the density of the liquor and therefore masks or obscures the alcohol content. In the USA the TTB allows distillers to use their "proofing by obscuration" method for liquors containing less than 600 mg of dissolved solids per 100 ml of spirit. WebFor example, if the weight of solids remaining after evaporation of 25 milliliters 0.125 gram, the amount of solids present in 100 milliliters of the spirits is 0.50 gram (4 times 0.125). The obscuration is 4 times 0.50, which is two degrees of proof. This value added to the temperature corrected hydrometer reading will give the true proof.
