Can I drink it? Rosemary simple syrup edition
June 30, 2018 1:56 PM   Subscribe

28 days ago I made a syrup with 1:1 sugar:water plus a bunch of rosemary. Used a little and forgot about it until today, and it had some sort of cloudy thing floating around the bottom. That's mold right? I can't tell if weird colony or just weird precipitate.

Hard to get a picture of but I tried.

I'm sufficiently grossed out by the idea of drinking mold that I would not even consider doing anything with that except for pouring it down the drain. My experience of refrigerated sugar syrup is that it does indeed grow mold after a few weeks.

The cloudy thing is definitely mold, or whatever thing it is that grows in 1:1 simple syrup. That always happens with mine after a few weeks.

For the next batch, I've heard you can extend the fridge lifespan by adding a bit of vodka. If you want really long lasting, you can use light corn syrup instead of the 1:1 simple, although you'd have to thin it out for easy use in drinks.

Stringy? 100% mold.

I wouldn't drink it. For future reference though, simple syrup freezes really well.

Was it refrigerated?

A 'rich' simple syrup (2:1 instead of 1:1) has a longer shelf-life. In the fridge, 2:1 will last about six months; 1:1 will last no more than a month, even in a clean and sealed container in the fridge, before doing the thing you're currently observing.

Yeah, that's mold. Pitch it. Next time, maybe freeze portions in an ice cube tray for doling out over time.

Down the sink he went. Lesson learned, add vodka or freeze next time.
