Noticed a typo in the last table...0.80 lb DME + 1 gal H2O yields 1.035 OG NOT 1.025... darn these fat fingers...

0.45 lb DME + 1 Gallon water = 1.020 OG
0.57 lb DME + 1 Gallon water = 1.025
0.68 lb DME + 1 Gallon water = 1.030
0.80 lb DME + 1 Gallon water = 1.035
0.91 lb DME + 1 Gallon water = 1.040
1.00 lb DME + 1 Gallon water = 1.044

Jensen,

So you add 0.125 lb DME per pt or 0.25 lb per qt?

When/how much of the yeast food do you add, if any?

I thought distilling water strips most if not all the minerals out and make the end solution a neutral pH sans ions?

I filtered my water to get the heavy metal and chlorine out and buffer the wort with 5.2. Am i missing something?

You are thinking about all-grain mash chemistry and water Jason. You need good water chemistry to get the best conversion and conditions for yeast when dealing with all-grain. With DME or LME the maltster has done all or the work for you and has made the best mash they can... it only needs re-hydrating, and distilled is the best answer. Actually "mineralized" water can undermine all their efforts-- this is true for starters and actual batches of brewing.

I only know the "10" rule, so I trust your math conversions are correct.

As far as yeast nutrient goes, it is hard to find concise data. What I use is a level 1/8tsp in my quart liter mason jars and 1/4tsp in my 1/2gal mason jars. I put it in the mix before the lid and band go on. Probably should try to really define the correct amounts for these, but yet have done so. I do believe that the brown powdered yeast nutrients are better to use than the white crystal yeast nutrient though.

Thanks for the water info, was stuck in "brew mode". Have not worked much with DME, went straight into all grain.

On the yeast nutrient, I use 10 g per 1 L (1.0 % w/v)

Thanks for all the input from everyone...good topic.

Andy, I have canning "envy", one hell of a setup. Beats the dog crap out of my little 8 qt deal
