Gents,

Hi, it's been a while since I've posted here at Tiki Central. The only Lemon Hart (and the only Demerara rum period) that's distributed in this area if the LH 151 (I know, poor me, right?). Problem is that I need way more of the 80° Demerara for everyday use, and I'm tired of mail ordering it. The 80° Dem is nothing but the 151° that's been diluted by the addition of distilled water to bring it down to 40% abv (Alcohol By Volume, which is 1/2 of the "proof"). So I want to take the LH 151 that I can buy locally and dilute it with distilled water down to 80°. Can someone help me with my math regarding how much water to add to a 750ml bottle of 151to bring it down to 80 proof?

If I'm calculating correctly, dividing 75.5 (the abv of the 151) by 40 (abv of the 80 proof) = 1.88. That's 88%.
Multiplying 25.5 (ounces in a standard 750ml bottle) 88% = 22.35.
So would adding 22.35 ounces of distilled water to a 750 bottle of LH 151 yield me a bottle of standard 80 proof LH?

Any help is greatly appreciated!
