Congratulations!! I rarely see someone say their first loaves of whole wheat bread came out well
. I cool my bread first, then put in a plastic bag overnight on the counter. The next day I slice the bread and put it all in the freezer. I remove the slices from the freezer as I need them. They are just like fresh baked.
It is best to store this bread either on the counter or in the freezer. Storing it in the refrigerator dies it out quickly. The quality starts to decline after about three days on the counter. That's why I freeze it all.
