Learning how to brew medium roast coffee at home in Murphy requires a 1:16 coffee-to-water ratio and filtered water. This method creates a balanced cup in about 5 minutes for only a few cents.
Brewing equipment for medium roast coffee
| Item | How much | Why it’s needed | A substitute |
|---|---|---|---|
| Coffee beans | 20 grams | Provides the base flavor | Pre-ground coffee |
| Water | 320 milliliters | Extracts the coffee oils | none — don’t swap this |
| Grinder | 1 unit | Ensures uniform particle size | Pre-ground coffee |
| Scale | 1 unit | Measures precise ratios | Measuring spoons |
| Kettle | 1 unit | Heats water to 200°F | Stovetop pot |
| Filter | 1 piece | Removes fine sediment | Metal mesh strainer |
Before you start
Clean your brewing equipment thoroughly to remove old oils. Rancid residue introduces off-flavors that mask the delicate notes of your fresh beans.
Use filtered water to prevent mineral buildup and off-flavors. High mineral content masks acidity and creates a flat, chalky mouthfeel.
Grind beans immediately before brewing. Oxygen exposure degrades volatile aromatics rapidly. If your grounds sit longer, you lose the floral essence that justifies buying premium coffee.
Don’t use boiling water. Aim for 195°F to 205°F. If you lack a temperature-controlled kettle, wait sixty seconds after the boil to avoid over-extracting bitter compounds.
How to brew medium roast coffee at home in Murphy
- Weigh 20 grams of whole-bean medium roast coffee using your digital scale.
- Grind the beans to a texture that looks like coarse sea salt.
- Heat 320 milliliters of filtered water to 200°F, which is the ideal range for medium roasts.
- Rinse your paper filter with hot water to remove any papery taste.
- Place the ground coffee into the filter and ensure the bed is flat.
- Pour 40 milliliters of water over the grounds to let them bloom for 30 seconds.

- Wait for the water to drain completely, which should take about 3 minutes total.
- Remove the filter and discard the grounds before serving the coffee immediately.
How to know it worked

The coffee should have a clear, bright color and a smooth finish without any harsh bitterness. If the brew tastes sour or thin, your grind was likely too coarse or the water was too cool. If it tastes overly bitter or heavy, your grind was too fine. A successful brew produces a consistent stream during the pour and leaves a flat, even bed of grounds at the bottom of the filter once the water has finished passing through the coffee.
If something goes wrong
| What happened | Why | What to do |
|---|---|---|
| Coffee tastes sour | Under-extraction | Use a finer grind |
| Coffee tastes bitter | Over-extraction | Use a coarser grind |
| Slow flow rate | Filter is clogged | Grind less finely |
| Weak flavor | Low coffee ratio | Increase coffee weight |
| Lukewarm coffee | Heat loss | Pre-heat your mug |
How often to do this
You can brew fresh coffee daily to ensure the best flavor profile. The frequency depends mostly on your personal consumption habits and how much coffee you store at once. If you buy a large bag, keep it in an airtight container away from light to maintain freshness for up to two weeks. If you notice the beans losing their aroma, increase your usage to finish the bag faster.
Frequently asked questions

Can I use tap water?
Yes, you can use tap water if it’s filtered to remove chlorine and odors. If your tap water has a strong metallic taste, it will negatively affect the final flavor of your brew.
Why is my coffee watery?
Your coffee is likely watery because the ratio of water to grounds is too high. Try adjusting your scale to ensure you’re using exactly 20 grams of coffee per 320 milliliters of water.
How long should the brewing process take?
The brewing process should take about 3 minutes from the first pour to the final drip. If it takes much longer, your grind size is likely too fine for your specific filter type.
Is it safe to leave coffee in the pot?
No, it isn’t ideal to leave coffee in the pot for more than an hour. The flavor will degrade quickly, and the heat source can cause the coffee to become bitter over time.
Does the roast level change the water temperature?
Yes, medium roasts perform best at 200°F, while darker roasts often taste better at slightly lower temperatures. Always check the coffee bag for specific brewing recommendations from the roaster.
What happens if I don’t bloom the coffee?
If you skip the bloom, the trapped gases in the coffee grounds will prevent even water contact. This results in an uneven extraction and a less balanced cup of coffee.
Final Thoughts
Once you’ve found your favorite local beans, try experimenting with your grind size to see how it changes the flavor profile. Don’t be afraid to adjust your technique until the taste is just right for your palate. You’ll soon look forward to that perfect, comforting mug waiting for you each dawn.
