How Much Coffee Should You Order? A Simple Bag Guide

How much coffee should you order? The most reliable answer starts with the grams of dry coffee your household actually brews each day. Once you know that number, you can calculate how many bags to buy, when to reorder, and whether a subscription interval fits your routine.

“Cups per bag” sounds simple, yet it can create confusion. A brewer’s cup and the mug you drink from may be very different sizes. Your dose also changes by brew method, recipe, and how many people reach for coffee each morning. A short measurement period gives you a plan that feels practical from the first bag to the next.

At Café Nairobi, that daily ritual begins with single-origin Kenyan Arabica from the Mount Kenya highlands. The coffee is shade-grown in mineral-rich volcanic soil, fully washed, sun-dried, and roasted in Jacksonville, Florida. Expect a smooth, low-acid cup with bright floral notes and full body—whether you are brewing one quiet pour-over or setting up coffee for a busy household.

How Much Coffee Should You Order? Start With Daily Use

Measure one typical week before placing a larger order or choosing a recurring delivery. Record every gram of dry coffee you put into your brewer. Include the coffee used for recipe testing and espresso dial-ins, since those beans still come from your bag.

1. Write down the dry-coffee dose for each brew.
2. Add the doses for seven days.
3. Divide the weekly total by seven to find your average daily use.
4. Check how much usable coffee is already in your pantry.

For example, a household that brews 20 grams every morning uses 140 grams in a week. A household that makes two 20-gram brews daily uses 280 grams each week, or 40 grams per day. The second household will move through coffee far faster, even if both describe their routine as “a couple cups.”

Use a kitchen scale when possible. Grams provide a repeatable measurement, while scoops and tablespoons vary with bean size, grind size, and how full the scoop is.

Begin with the recipe you already enjoy

Your successful recipe is the best basis for ordering. For filter coffee, Moccamaster suggests 55 grams of coffee per liter of brewing water, or 28 grams per 500 mL, as a starting point. Treat that as a useful reference for filter brewing rather than a rule for every device.

French press, pour-over, drip machines, espresso, and cold brew each call for their own recipe. Espresso is especially dose-specific because small adjustments can meaningfully change extraction and flavor. Keep using the dose that delivers the cup you enjoy, then let that dose guide your bag calculation.

Do the Coffee Bag Math in Four Steps

Once you have daily use, the calculation is straightforward:

Needed grams = daily use × days to cover − usable coffee already on hand.

Then divide the result by the bag weight and round up to a whole bag. Carry any leftover coffee into the next calculation. This approach helps you order for your actual calendar rather than guessing from a general bag estimate.

A 12-ounce bag contains about 340 grams of coffee. Here is what that means when you begin with no coffee at home:

• 20 grams per day: One 12-ounce bag lasts about 17 days. A 30-day supply is 600 grams, so plan on 2 bags.
• 40 grams per day: One 12-ounce bag lasts about 8.5 days. A 30-day supply is 1,200 grams, so plan on 4 bags.
• 60 grams per day: One 12-ounce bag lasts about 5.7 days. A 30-day supply is 1,800 grams, so plan on 6 bags.

These examples are planning tools, not freshness deadlines. You can split a month’s projected usage into smaller orders that better match how quickly your household opens a bag.

A worked example for a two-person home

Imagine two people each brew a 20-gram morning coffee. Their daily use is 40 grams. They have 100 grams left in an open bag and want enough coffee for the next 21 days.

Multiply 40 grams by 21 days for a total of 840 grams. Subtract the 100 grams already available. They need 740 grams more. Dividing 740 by 340 grams per 12-ounce bag gives a little over two bags, so they should order 3 bags.

That third bag creates room for a slightly stronger brew, a guest, or a few rounds of dialing in a new grinder setting. When the next order comes around, they count whatever remains and subtract it from the new calculation.

Choose a Bag Size That Matches Your Brewing Pace

Bag size should support fresh, enjoyable coffee throughout your routine. The National Coffee Association recommends buying smaller amounts for one or two weeks. Think of that as practical freshness guidance that you can adapt to your household’s pace and storage habits.

A 5-pound bag contains about 2,268 grams. At 40 grams per day, that is nearly 57 days of coffee. It can suit high-volume homes, offices, and serious daily brewers. For many households, several smaller bags make it easier to open coffee closer to the time you plan to enjoy it.

Keep unopened bags in a cool, dry place, and seal your open bag carefully between brews. Buy whole bean if you grind at home, then grind shortly before brewing for a particularly aromatic cup. Café Nairobi’s Kenyan coffee brings out floral brightness, full body, and a smooth low-acid character when you give the beans a consistent recipe and fresh grind.

Match the roast to the way you brew

Ordering enough coffee also means ordering coffee that suits your preferred method. A balanced daily drip routine can start with Café Nairobi’s Medium Roast Kenyan coffee, which offers the smooth, expressive profile many home brewers want from a dependable everyday bag.

For immersion brewing, Kenyan coffee roasted for French press brewing is a natural fit for a full-bodied pot to share. If espresso is part of your weekday rhythm, choose Café Nairobi’s Espresso Roast Kenyan coffee and include your dial-in doses in the weekly total.

Set a Reorder Point Before the Last Scoop

A reorder point is the amount of coffee you want left when you place your next order. It protects your routine by allowing for processing, transit, weekends, holidays, and a personal buffer.

Reorder threshold = daily use × planned calendar-day lead time, including your buffer.

Choose a lead time that feels comfortable for your location and schedule, then apply your own daily-use number. If you brew 40 grams per day and prefer to have 10 days of coverage once you reorder, your threshold is 400 grams. That is a little more than one 12-ounce bag.

Place your order when your usable coffee reaches that level rather than waiting until the bag is nearly empty. A simple note on your phone, a calendar reminder, or a label on the pantry shelf can make the habit easy. Recheck your lead time after a few orders and adjust your buffer to fit real life.

Make Sure a Coffee Subscription Fits Your Schedule

A subscription can simplify repeat purchases when its quantity and delivery interval match your actual usage. The key is doing the bag math first. At 40 grams per day, two 12-ounce bags last about 17 days, not a full month.

Before enrolling, confirm the available delivery intervals, quantities, charge dates, and skip or cancellation terms at checkout. After two deliveries, compare what arrived with what remains in your pantry. If bags are accumulating, extend the interval or reduce the quantity. If you are running low early, add a bag or shorten the interval.

Clean Coffee Is Part of a Confident Reorder

For label readers, dependable coffee means knowing what has been checked. Café Nairobi coffee has been third-party tested by Cambium Analytica, an ISO/IEC 17025 accredited laboratory. The reported results show yeast and mold at 0 CFU/g. Aflatoxins B1, B2, G1, and G2, plus Ochratoxin A, were not detected.

These results give customers a specific, documented detail to consider alongside roast preference, flavor, and origin. You can view Café Nairobi’s coffee lab results directly before choosing your next bag.

Frequently Asked Questions

How long does a 12-ounce bag of coffee last?

A 12-ounce bag is about 340 grams. At 20 grams per day, it lasts about 17 days. At 40 grams per day, it lasts about 8.5 days. Divide 340 by your own daily dose for the most accurate estimate.

How many bags of coffee do I need for a month?

Multiply your daily coffee use by 30, subtract the usable coffee you already have, and divide by the bag weight. At 40 grams per day with no coffee on hand, a 30-day supply is 1,200 grams, or 4 twelve-ounce bags.

Should I order a 5-pound bag or smaller bags?

Choose the size that fits your consumption pace. A 5-pound bag is about 2,268 grams and can work well for high-volume use. Smaller bags are practical for many households because they can be opened closer to when you plan to brew them.

When should I reorder coffee?

Reorder when your remaining coffee reaches your personal threshold: daily use multiplied by your planned calendar-day lead time, plus a buffer for your routine. Track this for a few orders and refine it as needed.
