That brandy, while cheap, is actually really good and mixes well with regular egg nog and chocolate milk (separately). (It's made locally here and I've been to the winery / distillery and they do a good job). I've tried a number of different boozes and this seems to work well. To each their own. Sadly I have a massive sweet tooth.
I love some eggnog and some brandy. Just not a fan of all the ”flavored" crap that is being manufactured. I find you can usually get a better product by blending your own ingredients - in this instance perhaps a decent vanilla extract. And the liquor industry generally does NOT have to disclose additives/adulterants in their products. For instance, Fireball "Whiskey" contains polyethylene glycol - an additive that prevents it's legal sale in Europe.
Many such products easily fall within the "goyslop" category. But yes - to each their own. Keep an eye out for my eggnog recipe though - good shit even without the littany of booze.
