Default Slotted Stainless vs. Perforated Stainless False Bottem

I've been looking into making a new mash tun for a while now to try out fly sparging and I was wondering if anyone knows which is more efficient: a perforated ss false bottom or a slotted false bottom. I spent some time looking through the archives, but I could only find comparisons between false bottoms and slotted manifolds.

Thanks,

Tommy

It doesn't matter as long as you have equivalent rinsing of the grains. See How to Brew - By John Palmer - Tun Geometry and Flow Potential

All things being equal, I suppose theoretically perforated would be better, since you can get more holes per sq in than slots. But I really don't think it matters.

Yeah, uniform flow is what you are after. I don't think in this case it is going to make a difference at all. As long as everything else is pretty much equal anyway.

Thanks for the responses. Looks like I'll go with perforated since there's no price difference.
