Sanitize Cold-Brewed Coffee?

[filthyastronaut]

Made a coffee porter recently that turned out real nice, and I shared those sanitation concerns. To play it safe, I opted not to make any cold brew and I just doused the beans in vodka and threw them in whole like dry hops for a week. It was likely a waste of vodka, but nothing wrong with a little insurance. It also avoids even remotely watering down the beer with added liquid. Another way to play it safe is to get Trader Joe's cold brew coffee concentrate and add that. If the package is opened right before adding, it will be sanitary.
