Brewing Process Logic - A Comparison of Methodology

When using a fabric filter and the full volume of mash water without sparging, the gravity is set when the mash is complete - unless adjusting for volume in the kettle or the fermenter - it is never diluted. In addition the pH is fixed in both the mash tun and the kettle. The entire sparge process can be eliminated, saving time, effort, equipment and energy expense. The use of one kettle, one burner, and one bag with no mash out produces comparable results to sparging.

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. They are released at mash temps and bind with proteins to form haze. In conjunction with a pH above 6, excess tannins are extracted and impart an astringent flavor - they can not be produced by pressure.

This title of the blog is a real question we received from a curious brewer.

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...

As time passes, more and more folks find The Brew Bag and wonder if the filtering capability could be applied to their processes. Some call and speak with us, while others simply order and include the name of their business in the address. The business name prompts us to call them and ask what they're up to and why they think The Brew Bag will solve their filtering issues.  We've filled two orders for commercial coffee brewers and based on a conversation with one on the East coast, we think there have been more but we don't recognize as them...

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.
