Makes a big difference in taste & burn! Improper cure either makes it burn too fast or doesn't stay lit. You can overdry then rehydrate and still have decent taste sometimes it's even helpful as it's a "cooler" smoke. If you ever are given something that's just too harsh to smoke, that's how I fix it. Dry the crap outta it then rehydrate it. At least it's smokable then.

Grew up around tobacco plants, granddad & dad were also big cigar & pipe smokers, that's how I learned the importance of proper curing.
