Munich should be mashed, as the starch is not converted like crystal malts. Technicially Melanoidin malt should be mashed too.
You can easily make change from steeping to mash with a small kitchen pot on your stove and a thermometer:
- Use 5 cups of water for every 1 pound of grain.
- Heat water to approx 160-165F (no hotter)
- Crush grains and put them in a muslin or nylon mesh bag
- Mix grain bag into the water, making sure to break up grain clumps in bag.
- Cover pot and let grain rest for 30 minutes in hot water.
- Add VERY LOW heat at 15 minutes, be careful not to burn muslin bag to pot. Temp should be no colder than 145F, no hotter than 160F. Do not add heat if you want to keep it simple to start.
- After 30 minutes, remove grain bag, let drip dry. Do not squeeze.
- Pour this new wort into your main boil kettle, add water and extract to complete the brew.
I hope this helps!
