Thanks mystic. Excellent ideas. I'm wondering if my probe is going to work again when it dries out. I presume it should. Anyone have experience.

Answered my own question (and learned to read at the same time). It was about three posts down from the post showing the technique. Just bake the probe and wire for 20 min at 350 (leave the plug outside the oven). let's see if it works.......... (30 min later)...............Yep, It works!!!!!

Thanks.

I used this digital candy thermometer with good results until I allowed the display to get wet with the battery in it (then it broke...). The only other problem I've found with it is it uses watch batteries.

Next, I made sure to hit all my temperatures properly. In addition, I used a digital probe thermometer to probe the grist during the BIAB and found I needed a lot more stirring and agitation than I normally use. My approach was to stir with a paddle and to move the grain around on the way to strike temperature by pulling up on 1 side of the bag and then the other to sort of roll the grain around in the bag. This worked very well. Finally, I did a 2 gallon batch sparge at 175 after mashing out. Overall I got 78% efficiency on a 15.5 lb grain bill. That is better than I have done. Add to that 2lb of sugar and this should be a nice brew!

Pitched yeast recovered from Pranqster Golden Ale. Already bubbling away.

78% on a 15.5 lb grain bill is a big improvement over what you were getting before! Just curious, how much water did you start with this time? (you mentioned adjusting for pH, but not volume)

Stirring enough to circulate the mash will make a big difference on making sure that all of the grist is at temp for the mash. I have found a traditional paddle can be a pain with the bag, so I went the route someone else suggested (not sure if it is back on this thread or a different one) of using a "wall board mud hand mixer" that can be found at most larger hardware stores for around $10. They basically look like a large potato masher with a longer handle, and stirring the mash with a vertical "plunging" motion is very effective and avoids getting your paddle twisted up in the bag.

here's a link to the one on HDs website.

To squeeze or not to squeeze ?
When doing extract with speciality grains the directions always say don't squeeze or you will get tannins, for BIAB it seems a lot of folks squeeze the bag. What is right?

here's a way to look at it.... in a commercial brewery where they are HUGE batches of beer. The weight of the grains alone pressing down on the grains at the bottom of a mash tun alone is greater than the amount of pressure you can apply by hand.

to extract tannins it takes PH that is to high along with high temp (mainly the PH as a decoction mash boils the grain and doesn't extract tannins). Squeeze that bag and enjoy the beer

Thanks!
I did my second BIAB last weekend and got to thinking about this, I won't worry.

I mashed with 7.5 gallons and sparged with 1.6 gallons.

That is a great idea. Thanks for that. I did notice that moving the bag up and down was very effective because it brought up hot water from the bottom of the keggle. But I would like to swap out the handle for a long one, maybe 2-3 ft.

The one I have (picked up mine from the local HD store so the link I provided should be the same thing) has a long handle already. Overall length with handle and mixer head is a few inches past 3' (sorry no tape nearby so I am estimating based on 12" ceramic tiles on the floor). Would imagine it to work fine in a Keggle as is.


For roughly $10 you can't go wrong. Perfect BIAB mash paddle.

Default Thanks for telling me what BIAB Brewing Means

Reading another thread about BIAB brewing (with no explanation of the term), I had to do a google search for BIAB. One of the links, of course, was HBT.

That click lead me here. So much information on HBT. I appreciate your taking the time to share your set-up, and to include pictures.

Although I am in a few beer clubs, and they are great, but finding HBT, via BargainFitting's Wayne, has been the icing on the beer glass. It gives you lots of good ideas, but the key is to brew, not just read, read, read, and I need to brew more.
