I was looking at my false bottom today and it has got a small "bow" in it from lots of use:rockin: It is for my keggle and it is very heavy duty. It got me thinking about all the weight pushing down on. Isn't this weight essentially "squeezing" the bottom of my grain bed? It just reminded me of how everyone tells you not to squeeze your grain bag because you might get some tannins from the husks. Now I have noticed a slight astringency in some of my beers. I wonder if it could be from batch sparging and draining every ounce of wort out my mash tun? Thoughts??
