Four Grain Ale

Last night I brewed what I call a Four Grain Ale. I used Oats, Wheat, Rye, and Barley. I based the recipe off some rye recipes. It came out to a nice mellow 1.046 original gravity, I wasn't aiming for anything to  high in alcohol. I attempted to brew this as a partial mash and comparing with my Beersmith notes It looks like I hit about 70 percent efficiency.I added a majority of the extract in late to keep the color light.
