Squeezing the bag of grain and tannins are not synonymous. Excerpted and paraphrased from the books “Water - A Comprehensive Guide for Brewers” and “Malt - A Practical Guide From Field to Brewhouse” - Tannins, a subset of polyphenols, are present in grain husks and cell walls.

In conjunction with a pH above 6, excess tannins are extracted and impart an astringent flavor - they can not be produced by pressure.

Have you considered making bags to fit mash tun coolers for sparging?

This title of the blog is a real question we received from a curious brewer. It's worth noting that we have a photo of a cooler on the first page of our site, and yes, we've made hundreds of cooler bags. Perhaps brewers are beginning to realize that The Brew Bag, a fabric filter, is simply an alternative to the PVC, copper, or braided cord filter, and that using fabric simplifies lautering and makes for a stress free brew day. A stuck sparge can be a thing of the past. Spending hours constructing the mash tun filter can be a...

PVC Manifold Help Page - actual comments from non-fabric filter users.

mash tun PVC manifiold stuck sparge

Mines not glued either but I made slits in my manifold I had holes but kept getting plugged I don't have my manifold glued. I take it apart after every mash and its real easy to clean that way. You guys ever use a braided tube(outside mesh of a washing machine hose)? Any difference in efficiency, draining time etc? DONT glue it, makes cleaning much easier. Also, turn the holes downwards, so they don't get clogged as easy and if still having drainage issue, wrap the thing in a "boil in a bag" bag and then have fun  If your efficiency is...

So, you're into your brew day, and as usual you think "what if I could transfer ALL the sugars left in the grain to the boil kettle, there's beer waiting to be born!" And then you brew, clean up, have a brew, and realize you made 5 or 10 gallons in 3.5 hours (BIAB), or 6 hours (non BIAB), so you have another brew and forget about it.
