You’ll have better results with DME, not LME. Because all minerals were included when the extract was made, use distilled water, but you can add sulfate of chloride for flavor if you want to… No pH worries unless you start steeping a lot of grain.
I think so too that’s why I’m going to do it. Short of a long story I’m s tradesman but my ankle won’t last the next 25 years of my career. I’m a pretty good cook, especially southern BBQ. I hope to open a small BBQ and beer shack. It’s something our small town is missing.
Water adjustments
Water for the boil should have alkalinity below 50 ppm. The need for adjustment depends on your water. Bru’n Water can help figure how much acid to use.
CaCl and gypsum might help, depending on your water and the extract manufacturer’s mash water chemistry. Making up dilute solutions and adding to a glass of beer can help you decide whether, and how much, to add.
DMS: It doesn’t seem to be a problem. I’ve never had a problem with it, even when doing covered hop stands.
Adding LME: Late extract addition has become popular. I add enough extract at the beginning to get about 1.040 SG in the boil. Then add the rest at flameout. Also, make sure the kettle bottom won’t scorch the extract - I wait one minute after taking it off the burner before adding extract.
I’ve gone to a 40 minute boil. This seems to be getting popular.
There is at least one LME you can’t get in DME form. That is Briess Munich. That one is 50/50 Munich/Pils malt. I think some of the recipes will benefit from Munich malt. If you see Munich in the book’s all grain version you might try to use it in the extract version.
Another place to consider LME is when you want to use continental malts. William’s brewing has several LME varieties based on European malts.
