Default Help! In the middle of my first mash!

I'm brewing a 1 gal SMaSH right now with 2lbs of Marris Otter malt- I calculated that I was going to get a gravity of 1.050 from the malt, but I just sparged and checked the gravity, and it is only at 1.025.

My thermometer is a piece of **** so the mash was all over the place (I can barely read the damn thing)

I sparged into colonder & muslin bag so the grains are still in the bag. I'm currently thinking I should switch to a brew in the bag on the fly, til I get closer to my intended gavity. Is this plausable? I really don't know what to do, this is my first time doing all grain.

As wort reduces during the boil your gravity will increase.

If you sampled the wort hot, that will also give you a false low gravity reading...a one gallon batch, what is that a starter?

Get yourself a good thermometer. When you extract brew the temperature isn't really critical but for mashing you need good temperature control. The difference between mashing at 152 and 148 is a big difference. That mistake caused me to get a very dry red ale as it finished at 1.002 instead of 1.015 like I intended.

Which thermometer do you use?

I actually use 3 thermometers, a Taylor digital (stem is too short, I have to hold it in the mash), a long stem dial thermometer that I can clip to the side of the pot or insert through a hole in the lid (favorite as I can see the temperature rise as I mill my grain) and a glass lab grade that I use to verify the accuracy of the dial as I approach strike temp. I don't like using the glass thermometer but it is the best trade-off for accuracy and reach.

Thanks for the help, folks! Gravity ended up a bit short (.006 short) but I think it was a water miscalculation. Holy hell, I hate that thermometer! Grabbin a new one before the next batch for sure!
