Harvard Cocktail

Many historical versions lack the grenadine called for here.  See, e.g. https://www.reddit.com/r/cocktails/comments/2msxfz/not_cocktail_of_the_week_98_harvard/

This is a promising "Manhattan with brandy instead of whiskey" & the low rating may be due to the cloying sweetness I'd expect with that much grenadine.
