Do You Have To Thaw Frozen Coffee Beans Before Grinding?
Coffee and convenience are intertwined; for many, the beverage is an essential start to the day. Yet the coffee beans themselves are surprisingly delicate, and require care for optimal freshness. Once exposed to air, they'll only have around two weeks to remain flavorful. Simultaneously, the coffee roast date matters, too, which means you'll need to wait on a bag of fresh beans to lose gas.
For those who buy in large batches, chasing such a fresh window is complicated, so they turn to the freezer instead. Although the storage method does affect the flavor, it's a better bet than beans sitting on the shelf for months. In fact, if you freeze coffee beans the right way, then you'll even contain some of the fresh aromas.
Once you're retrieving those chilled beans, you may wonder if it's necessary to thaw them. The answer's contentious: Some baristas grind straight out of the freezer, while others prefer a slow overnight thaw. So as long as you have an ideal freezing process in place, then don't stress over the warming step — it won't damage your grinder.
Thawing frozen coffee isn't essential, but keep an eye on exposure to moisture
Prior to making a decision regarding thawing, it's helpful to understand the interactions of moisture and coffee bean quality. To put it succinctly, vapor is hugely detrimental to beans. Their structure soaks in airborne aromas, a reason why the fridge is not an apt storage place for coffee beans. Plus, moist air leads to rapid loss of flavor and even mold growth.
As a result, it's paramount to keep moisture in check. Ideally, vacuum seal your coffee before freezing, and don't open the package during storage. Furthermore, you don't want to refreeze your coffee beans again, so ration out portions that you'll use in one go. If you do choose to wait for them to thaw, then let the unopened bag slowly come to temperature in the fridge. Any amount of condensation on the bean will hurt the flavor, so if you do need to store them afterwards, keep them in an airtight container. Ideally, you'll need an efficient brewing process in place. So use a machine hack to craft some iced coffee in an instant, sip, and enjoy — that's when the fun part arrives.
