However, as fermentation begins, yeast consumes sugar and produces ethanol. Alcohol has a lower refractive index than water, which artificially depresses the Brix reading. Therefore, post-fermentation, a hydrometer is required to measure specific gravity. Or specific correction formulas must be used to account for alcohol presence.<\/div>\n<div class=\"ace-line ace-line old-record-id-Xz0Wd6XI8oE4Hdxsbl3cPI0snGe\"><\/div>\n<div class=\"ace-line ace-line old-record-id-WF0pddcpMoxbLqxM301cIWmynce\">Trong c\u00e1c \u1ee9ng d\u1ee5ng c\u00f4ng nghi\u1ec7p, ch\u1eb3ng h\u1ea1n nh\u01b0 qu\u1ea3n l\u00fd dung d\u1ecbch l\u00e0m m\u00e1t kim lo\u1ea1i ho\u1eb7c ch\u1ea5t ch\u1ed1ng \u0111\u00f4ng, ch\u1ec9 s\u1ed1 Brix \u0111\u01b0\u1ee3c s\u1eed d\u1ee5ng nh\u01b0 m\u1ed9t \u0111\u1ea1i di\u1ec7n cho n\u1ed3ng \u0111\u1ed9 dung d\u1ecbch.
