Default Batch and Fly sparging. Whats the difference?

Kinda ridiculous but Im having trouble figuring out the difference between batch and fly sparging. Can anyone explain it in Leymans terms for a knucklehead like myself?

Fly sparging is a continuous rinsing of the grain, water in equals water out of the mash tun. The tun is drained out the bottom as sparge water is added to the top continuosly w/out stirring the grain.

Batch sparging is where "batches" of sparge water are added to the tun, stirred and drained completely, and then repeated 1 or a few times.

Some argue fly sparging has benifits, but IMHO batching is simpler and less equipment sensitive, yet will also produce acceptable results.

In fly sparging do you keep rinsing with wort, or keep adding new liquor?

You add water, generally from the HLT with a hose or other system with a gentle inflow as to not disturb the grainbed or to flow faster than the draining. About an inch of water above the grainbed is sufficient. Usually, a fly sparge (also continuous sparge) takes 40-60 minutes.

Batch spaging is better!

I just did my first fly sparge on my last batch, I didn't notice a huge differance in the wort so far but I added another 5% efficiency over my normal 70%. I will try it again this weekend to see if it was a fluke or if it really is better (for me).

With the right equipment and done properly, fly sparging can produce a slightly higher efficiency than batch sparging; but with the wrong equipment, or done improperly, fly sparging can be much less efficient because of channeling. It is also very easy to over sparge when fly sparging resulting in excess tannin extraction, while it is virtually impossible to do this with a batch sparge.

I can get over 90% batch sparging, averaging 87%. Fly sparging is a waste of my time and money.

Here is a pretty comprehensive run down of both sparge procedures along with some pros and cons... good read.

Batch vs Fly is as rediculous as Aluminum vs Stainless, Pellet vs Leaf, HERMS vs RIMS or Chill vs No Chill. None of them, really matter or make that big of a difference. You will probably screw something up that is simple, that would contribute more to a difference in your final product than any of these differences combined.

People like thier soap boxes... but none of the above make an appreciable difference in your beer. Do what fits your style or your system. After all, this is just a hobby.
