2 bags...1 tun

[Juiceyfruit152]

Hello All,

I'm going to brew an imperial Oktoberfest and I plan on indulging in my hard work when Oktoberfest come around in 2018. I have come to the point that the grain build that is being required is starting to exceed the amount of space in 1-5 gallon bag (Muslin or painters bag). With Macguyver skills and the forum and other resources I've been able to use a large cooler. As I've started to make high gravity brews I've started to run into the issue with the bag not being able to completely close. I've looked at the option of using cheese cloth, but the issue is cloth isn't wide enough holdall the grain. It may be a silly question, but if I was to use 2-5 gallon bags would the word be effected if I added the wort to my cooler. I've never separated the grain, but I think its possible. Any insight would be helpful The information for the recipe is below.

You can get a @wilserbrew bag or go the stainless braid with valve

And yes it is possible using 2 bags

You can buy Swiss Voile curtain material and make a custom bag to fit your cooler, buy one custom made by wilserbrewer, or use 2 bags. It all works.

I typically do biab for most of my beers, but I made a tun out of a cooler with a braid tube for larger grain bills. I batch sparge and have been seeing 75% or higher efficiency.

This is exactly the method that I use. However I have gotten to the point where my grain builds are starting to exceed the bags I'm using. I have been told I should just modify the cooler and dump the grains in but I like the easy cleanup method of just tossing the used bag and rinsing the cooler. I usually yield a 75% efficiency.
