You may have missed my answer to your question on new_distillers.
Actually, it's a persistent but incorrect myth that foreshots removal is strictly to remove methanol from the collected spirits. Most importantly, foreshots removal is for reducing the unpleasant flavors from the spirit, and I'm told (and I'll take the authority's word, here) that methanol is undetectable by taste in ethanol (it tastes like slightly sweetened ethanol). Foreshots are where the highest concentrations of acetone, acetaldehyde, furfural, and traces of other low-boiling, bad-tasting stuff are. If there also happens to be methanol in the wash, while it won't be tasted, some of it will be removed from the collected spirit.
So, yes, discard the foreshots from a sugar wash.
