Now that I have a few batches under my belt (literally) I am starting to look for recipes on the web beyond the basic kits and I have noticed that some instruct to steep the specialty grains in 1 gallon of 150 degree water, then strain back into the brew kettle, and then sparge the grains with another gallon of 150 degree water. All of the kits and recipes I have brewed thus far have specified steeping the grains in a bag and the kits include a bag. Is there any difference one way or the other? Steeping without the bag definitely is not as easy, but maybe has better saturation due to the exposed surface area?
