Keely's beer bread

My cousin-in-law Keely sent me a recipe for a simple beer bread

3 cups mixed grain self-rising flour
2 Tbsp sugar
1 cup beer, warmed to 110 degrees

Mix flour and sugar in a large bowl. Add beer and mix well. Knead on floured surface until smooth. Place in an oiled bowl and let rise one hour or until double in size.

Punch dough down and shape into a loaf. Place in loaf pan and cover lightly with Sarran Wrap. Let rise 30 minutes.

Bake at 375 degrees for 30 minutes. How to tell if your bread is done?
