Do you need filtered water for cold brew?
That said, filtered water is generally a good choice for making cold-brewed coffee. Water filtration systems work by removing undesirable minerals from drinking water. But they usually do not filter out the calcium and magnesium that makes water hard – because, remember, hard water makes tastier coffee than soft water.
Can I use a plastic container for cold brew?
Choose your container
You can steep coffee for cold brew in just about any watertight vessel, from mason jars or glass pitchers, to even plastic buckets.
Is cold brew coffee potentially hazardous?
Overall, our survey results indicate that most cold brewed coffees are safe for consumption as most samples appear to have been produced under sanitary conditions. However, contamination by bacterial pathogens can occur occasionally, and a loss of sanitation controls along the food production chain can occur as well.
What is the shelf life of cold brew coffee?
Unlike hot coffee, which is pretty much crap after a few hours, cold brew will keep in your fridge. As an undiluted concentrate, it’ll keep for up to two weeks, although the flavor quality will degrade after the first week. If you’ve cut the concentrate with water, that shortens the shelf life to a mere 2-3 days.
Does cold brew have to be made in an airtight container?
All you’ll need are pods, a pitcher or an airtight container (the latter is recommended to prevent a slight film from forming on the coffee’s surface), and pods.
