How Much Coffee for French Press? The Golden Ratio Made Easy

TL;DR:

The magic ratio for French press coffee is **1:15** — that’s **1 gram of coffee for every 15 grams (or ml) of water**. For a standard 8-cup French press (1 liter/34 oz), use **60 to 70 grams of coffee** for a strong, balanced brew. That’s about **8 to 10 tablespoons** of coarsely ground coffee. ---

Quick Buyer Checklist

• French Press Size: 12 oz, 17 oz, 34 oz, or 51 oz?
• Coffee Roast: Medium to dark works best for French press.
• Grind Size: Use a coarse grind — think sea salt texture — to avoid sediment and clogging.
• Scale: Do you have a digital scale? That’s your new BFF.
• Beans: Fresher is better. Check out the Gaia line at Upscale Coffee.

Core Guide: Your Perfect French Press, Step-by-Step

Planning & Setup

Before brewing, measure how much coffee your press makes. A “3-cup” French press doesn’t give you three diner mugs of coffee—it gives you closer to 12 oz. Sizes range from travel-friendly single servings to party-sized presses. Bring your **filtered water** up to a near boil (195–205°F). Meanwhile, grind your beans coarsely and weigh them according to your ratio. We'll show you exactly how much to use. ---

Beans & Water

Here’s a cheat sheet for common press sizes:

• 12 oz press: ~23 g coffee / 345 g water (≈3 tbsp)
• 17 oz press: ~33 g coffee / 500 g water (≈5 tbsp)
• 34 oz press: ~60–70 g coffee / 1,000 g water (≈8–10 tbsp)
• 51 oz press: ~90 g coffee / 1,350 g water (≈12 tbsp)

Pour your hot water steadily into the coffee, stir gently with a wooden or plastic spoon, and cover. ---

Dial-In & Daily Routine

Set a timer for 4 minutes. When the timer dings, press down slowly and evenly. If it feels too loose or too tight, your grind may be off. Not strong enough? Add more coffee or steep longer by a minute. Too bitter? Shorten your steep time or coarsen your grind. ---

Maintenance & Longevity

Rinse all parts after every brew. Coffee oils love crusting onto mesh filters and glass bodies. A deep clean weekly with soap and warm water keeps your press—and your brews—fresh. Upscale Coffee stocks replacement French press filters, descalers, and grinder brushes that help keep your setup in prime shape. ---

Troubleshooting & Pro Tips

8 Common French Press Problems and Quick Fixes:

1. Coffee is too weak: Increase your coffee dose or extend steep time to 5 minutes.
2. Coffee is bitter: Steep for less time or use a coarser grind.
3. Plunger gets stuck: Coffee is ground too fine—grind coarser to sea salt level.
4. Too much sludge: Use a consistent burr grinder and don’t press all the way down.
5. Brews taste stale: Use fresher beans. Once ground, coffee stales in hours.
6. Glass carafe smells: Deep clean weekly with a mild baking soda scrub.
7. Foamy top layer (bloom) is missing: You may be using over-roasted or de-gassed beans. Try fresh Gaia beans from Upscale Coffee.
8. Uneven extraction: Stir right after pouring water, before placing the lid on.

Cost of Ownership

French press brewing is refreshingly affordable. Here’s what a year of good brews looks like: - **Beans (premium, fresh roasted):** $15 per 12 oz bag × 25 bags/year ≈ **$375** - **Grinder upkeep and filters:** ≈ **$25/year** - **Descaler for hard water areas:** ≈ **$10/year** - **Total Estimate: ~$410/year** With optimal care and low equipment failure rates, French press can be a low TCO (total cost of ownership) brewing method with no electronics or moving parts to worry about. ---

Sustainability & Health Notes

French press brewing is incredibly sustainable: - **No paper filters, no pods, no waste.** - Most presses are built from **glass, stainless steel, and BPA-free plastic**. - Compost your coffee grounds in your garden or houseplants. - Pro tip: The press method retains coffee oils, boosting antioxidants and mouthfeel—but if cholesterol is a concern, limit pressed coffee or intersperse with a filtered brew like a Moccamaster. ---

While French presses are simple tools, not all are created equal. At Upscale Coffee, we judge presses based on:

• Heat retention: Does it keep your brew warm for the full steep?
• Durability: How well does it stand up to daily use?
• Filter screen quality: Does it strain out fine grounds efficiently?
• Ease of cleaning: Removable components? Dishwasher-safe?
• Aesthetic: Do you want this on your countertop forever?

We only stock what we’d brew with at home—and we’re picky. ---

FAQs: French Press Brewing 101

1. What grind size should I use for a French press?

Use a coarse grind, similar to kosher salt. A burr grinder gives you the most consistent results—better flavor, less sludge.

2. Can I use pre-ground coffee?

You can, but most pre-ground coffee is too fine for French press. Expect more grit and over-extracted notes. If you must, look for French press–specific grinds.

3. Why does my French press coffee taste bitter?

Likely causes: steeping too long, using too fine a grind, or extra-dark beans. Start with 4-minute brews and adjust.

4. Does French press brew stronger coffee than drip?

It can, since it retains natural oils and finer particles. Flavor can be richer and bolder—but also more variable.

5. How many tablespoons is 30 grams of coffee?

Roughly 4 tablespoons. But volume varies by grind, so a scale is recommended for repeatable results.

6. What’s the best water temperature?

Aim for 195–205°F. That’s just off boil. Boiling water can scald the grounds and dull the taste.

7. Can I use dark roast coffee in a French press?

Absolutely, many do. Just ensure your beans are fresh and your grind coarse—it can be a match made in morning heaven.

8. How long should I wait before pressing?

Four minutes is the golden window. Stir once, place the lid, and let it steep.

9. How do I clean my French press?

Rinse after each use, deep clean weekly. Use a bottlebrush, mild soap, or baking soda to scrub oils stuck on the filter or carafe.

10. What’s better—glass or stainless steel French press?

Glass lets you see the brew and is classic, but can break easily. Stainless steel holds heat better and is more durable—great for daily brewers. --- Want a press that matches your pace? Visit Upscale Coffee to explore our curated gear and Gaia beans—your morning ritual deserves more than a guess.
