Im trying to work up a chart to determine the amount of Maltodextrin per gallon to raise the SG of beer or wort by 0.001 or the brix by 0.26. I know that typically brix is a measurement of grams of sucrose/ 100g of solution. But im not sure if that can be directly translated to a measurement of Maltodextrin. Is there a known weight correlation between sucrose and maltodextrin or do I need to determine this through an all day ordeal in the lab?
 
A large part of the utility of the Plato scale derives from the fact that an x% w/w solution of 'sugar' has a specific gravity close to that of sucrose regardless of what that sugar is (among the common ones at lest). Thus an x% sucrose solution is, by defintiion, at x °P and so are x% glucose, fructose and invert sugar solutions (though there are small differences). And so on for maltose and even the dextrines (to the point that they are soluble.)

Yup, 20 grams of Maltodextrin diluted with Distilled water to a 100 gram end point read 20 bris on both a refractometer as well as with a hydrometer. It was awfully difficult to dilute the maltodextrin in 70 degree water.
