Please help with hyrbid BIAB/batch sparge cheap mash tun!
Hello fellow brewers!
We are beginners and live in an apartment so we don't have a lot of space. We also have a pretty tight budget. This is not our first brew but we're definitely still novice brewers...and for some reason we thought it would be a good idea to try an all-grain brew!
Since we're space limited, we're doing a 1-gallon batch as our first foray into all grain brewing. We are trying to make a cost-effective 2 gallon cooler mash tun. We're not really looking into any ball valve or woven steel manifold stuff, mostly because it's a little more complicated and would require the additional purchase of tools to be able to build it properly. We may want to do this in the future with a 5-gallon set up, but we need more space and time to invest.
After reading some of Palmer's book and perusing these forums, we want to try to do a BIAB/batch sparge hybrid...a grain bag on top of a false bottom, basically.
For the false bottom, we're thinking of putting some glass marbles in the cooler to come up right above the spigot, then topping that with a layer of wire mesh fitted into silicone piping so that it's flush against the sides of the cooler. On top of that mesh we will put our grain bag. We want to try to mash, recirculate and sparge all in this container.
Does this sound like something that would work?
We've also seen a cheap build using a steamer basket as a false bottom, then a brew bag on top...any thoughts on which one is better/more effective?
Why do you want to use a false bottom? False bottoms are intended to help the grain create a filter bed so your wort will come out without all the grain particles. With BIAB, the bag creates the filter. You really don't need to use the cooler either, just put the correct amount of water in the pot, bring it to temperature, put the bag into the pot and stir the grains in so they don't clump up.
At the end of the mash period, pull the bag out and let it drain a bit, slip a pan with a colander inside it under the bag and set it on the counter to let it drain some more. As it drains, add the wort collected to the pot. If you aren't getting enough wort to fit the recipe, pour some cold water into the bag of grains and stir a bit, then squeeze it all out and add that to the pot.
Yea just use the pain bag in the cooler. When you pull the bag set it in a collendar over a big pot and using coffee cups, one in each hand press every drop of wort out of the grain.[IMG][/IMG]
