River Rock Roasting Company Coffee Guide

River Rock Roasting Company is a coffee roaster, not a single dish, so there is no one recipe associated with the name. This practical guide shows how to brew its whole-bean coffee as a balanced pour-over, with clear measurements, timing, and adjustments for different brewing preferences.

Ingredients

30 g (about 5 tablespoons) River Rock Roasting Company whole-bean coffee
500 ml (2 cups plus 2 tablespoons) filtered water
Additional hot water, about 250 ml (1 cup), for warming the brewer and serving vessel; discard before brewing

Instructions

Heat and rinse. Bring the water to a boil, then let it stand for about 30 seconds; aim for roughly 200°F (93°C). Meanwhile, place a paper filter in a pour-over dripper set over a heatproof carafe. Pour the extra hot water through the filter to rinse away any papery taste and warm the dripper and carafe. Discard the rinse water.
Grind the coffee. Grind 30 g of beans to a medium-fine texture, similar to table salt. Grind just before brewing for the clearest aroma. If using pre-ground coffee, choose a medium grind intended for drip brewing and keep the same weight.
Add the grounds. Tip the grounds into the rinsed filter and gently shake the dripper so the bed is level. Set the dripper and carafe on a scale and tare it to zero, if available. A scale makes it easier to repeat the 1:16.7 coffee-to-water ratio.
Bloom the coffee. Start a timer and pour 60 ml (¼ cup) of the brewing water evenly over the grounds, making sure they are all wet. Wait 30 seconds. Fresh coffee may bubble as trapped gas escapes; this is normal.
Pour in stages. Slowly pour in about 220 ml (scant 1 cup) of water in a gentle spiral, starting in the center and moving outward without pouring directly onto the filter walls. Let the water level fall slightly, then pour the remaining 220 ml (scant 1 cup) the same way. Pour steadily rather than in a strong stream that disturbs the coffee bed.
Let it drain and serve. The full brew should take about 3½ to 4 minutes from the first pour. Remove the dripper when the water has drained; a small amount of water left in the grounds is fine. Swirl the coffee in the carafe to even out its strength, then pour into two cups. If it finishes much faster or slower, adjust the grind as described in Tips.

Tips

Use the grind to correct the timing. If the coffee drains in under 3 minutes and tastes thin or sour, grind a little finer. If it takes over 4½ minutes and tastes harsh or bitter, grind a little coarser. Make small changes so you can tell what helped.
Adjust the strength by weight. For a lighter cup, try 27 g coffee to 500 ml water; for a stronger cup, try 32 g. Keep the pour method the same while changing the ratio, rather than changing several variables at once.
Water matters. Filtered water with a clean, neutral taste helps the coffee’s character come through. Very hard or strongly chlorinated water can make a cup taste dull or unpleasant; avoid distilled water, which can produce a flat-tasting brew.
Store beans well. Keep whole beans in an airtight container in a cool, dry cupboard, away from sunlight, heat, and moisture. Avoid refrigerating beans, where they can absorb odors and condensation. Grind only what you need for each brew.

Serving Suggestions

Serve the coffee freshly brewed, either black or with milk, cream, or a plant-based alternative. A small amount of sweetener is optional; taste the coffee first, since different roasts can vary in bitterness, sweetness, and acidity. It pairs naturally with breakfast pastries, toast, oatmeal, or a simple afternoon snack. If serving a group, prewarm the carafe and pour soon after brewing so the coffee stays hot without sitting on a heating plate, which can make it taste stale.

Variations

Make a single cup: Use 15 g coffee and 250 ml (1 cup plus 1 tablespoon) water. Keep the same grind and pour stages, scaling the bloom to 30 ml (2 tablespoons). The smaller batch may drain slightly faster.
Use a drip coffee maker: Add 60 g coffee per 1 liter (4¼ cups) of water as a starting ratio. Use the machine’s paper filter and follow its normal brew cycle; adjust the coffee amount to taste.
Try a French press: Use 30 g coarsely ground coffee and 500 ml hot water. Stir gently, steep for 4 minutes, then press slowly and serve immediately to limit continued extraction.
Brew it over ice: For two servings, use 30 g coffee and 300 ml (1¼ cups) water, then brew directly over 200 g (about 1¼ cups) ice in a heatproof carafe. The melting ice brings the finished drink close to the original volume. Use a slightly finer grind than for the standard pour-over if the result tastes weak.

Storage and Reheating

Fresh-brewed coffee is best served promptly. If you have leftovers, transfer them to a clean, covered container and refrigerate within 2 hours; use within 3 to 4 days. Reheat only the amount you plan to drink, in a microwave-safe cup or small saucepan, until hot, and avoid boiling it because that can intensify bitterness. Refrigerated coffee also works well poured over ice. Do not leave brewed coffee with milk at room temperature for more than 2 hours; discard it if it has been sitting out longer.

Frequently Asked Questions

What coffee-to-water ratio should I use?
Start with 30 g coffee to 500 ml water, approximately a 1:16.7 ratio by weight. A kitchen scale gives the most consistent results, but the listed tablespoon measure is a practical backup; bean size and grind make volume less exact.

What grind should I use for pour-over?
A medium-fine grind, roughly like table salt, is a useful starting point. The right setting depends on the dripper, filter, and grinder, so use the brew time and taste together to guide adjustments.

Can I use pre-ground River Rock coffee?
Yes. Choose a grind labeled for drip coffee or pour-over and use 30 g for 500 ml water. Pre-ground coffee loses its aroma faster than whole beans, so keep the bag tightly closed and follow its freshness guidance.

Why does my coffee taste bitter?
Common causes include a grind that is too fine, water that is too hot, or a brew that drains slowly. Try a slightly coarser grind first and keep the pour gentle. Also check that the coffee and filter are fresh and clean.

Why is my coffee watery or sour?
A very fast drain, coarse grind, or too little coffee can leave a cup weak and under-extracted. Grind a little finer or increase the coffee slightly, changing one thing per brew so you can identify the cause.

Does the name refer to a specific roast or blend?
The name alone does not identify a particular bag, roast level, or flavor profile. Check the package for the coffee’s origin, roast date, and recommended brewing notes, then use this recipe as a starting point rather than assuming every coffee will taste the same.
