Freezing Coffee: Does it REALLY Affect Your Grind Size?

Unlocking the secrets of coffee preservation!  Many coffee aficionados focus on roast level and brewing methods, but what about freezing?  This post dives into the fascinating world of how freezing impacts your coffee's grind size and flavor profile, especially for light and ultralight roasts.  I've been meticulously tracking micron changes in my Aeropress and flat burr grinder setup, discovering a consistent coarsening of around 5 microns per week.  However, freezing introduces a wild card. While some frozen coffees behave similarly to their non-frozen counterparts, others, like one I froze for two months, exhibited unexpected muted and astringent flavors—a clear sign of over-extraction. My experiments suggest that freezing might slow down the 'sweet spot' shift, but the effect isn't consistent.  Some sources claim one month of freezing equals 2-3 days of aging, which aligns with my recent findings. To revive my two-month-frozen coffee, I had to adjust my grind size significantly coarser than usual—a testament to the subtle yet impactful changes freezing can cause.
