Coffee is a multi-billion-dollar business. However, is it a good dropshipping niche?
In this post, we’ll try to answer whether you should dropship coffee and coffee-related products such as coffee machines or coffee mugs. And, if you insist on starting a coffee dropshipping business, we’ll also show you the best tips and resources to start selling coffee products without inventory in a smart way.
Is Coffee A Good Dropshipping Niche?
Coffee is not a good dropshipping niche. Although the global coffee market is enormous, which was valued at $102.02 billion in 2020 and is anticipated to register a CAGR of 4.28% over 2021-2026, it’s highly competitive and dominated by established players. They are Nestle, JM Smucker Company, The Kraft Heinz Company, and Starbucks Coffee Company.
By 2025, researchers predict that 84% of spending on coffee will be attributable to out-of-home consumption. This essentially means that unless you’re a wholesaler, the eCommerce coffee segment left to dropship is not that big.
In addition, private-label brands, such as Massimo Zanetti Beverage Group or Tchibo GmbH, are regularly engaging customers with innovation and expansion strategies, making the competition even more fierce.
What is more, over the past few years, consumers are getting more conscious about coffee manufacturing. As a result, they’re constantly looking for the credibility of their coffee purchase.
Having said that, if you’re an experienced dropshipper, you can still compete in this niche with trustworthy coffee suppliers, unique selling points, and creative marketing strategies.
How About Dropshipping Coffee Machines And Other Coffee-Related Products?
According to GrandViewResearch, the global coffee machine market size was valued at $5.88 billion in 2018 and is anticipated to expand at a CAGR of 3.7% from 2019 to 2025. Although it’s highly competitive with prominent companies like Keurig, Panasonic Malaysia, Nestle Nespresso, De’Longhi, Electrolux, or Morphy Richards, there isn’t a brand that truly stands out.
For example, statistics show that leading companies that sell office coffee machines only account for 34% of the overall market revenue.
Hence, we think you have a chance to compete in the coffee machine dropshipping niche and make some money out of it.
Regarding other coffee-related products like coffee mugs or coffee tumblers, we don’t have any concrete numbers for them. But, they should be fairly easy to dropship.
How Much Money Can You Make Dropshipping Coffee?
Now, it comes to the most important question you need to ask before jumping into the coffee dropshipping niche: “How much money can I make?”
To answer the question, let’s do a little bit of math.
The average customer lifetime value of a coffee eCommerce brand is $203. With an average conversion rate of 10% and a profit margin of 10%, if you get 10,000 visitors to your store, your profit would be 10,000 * $203 * 10% * 10% = $20,300.
Advantages And Disadvantages Of Dropshipping Coffee
Understanding the benefits as well as drawbacks of dropshipping coffee will allow you to better prepare and adapt to various circumstances during your business life cycle.
Below are the benefits:
- Large Audience Base: There are at least 1 billion coffee drinkers worldwide. In the US, 63% of adults regularly consume coffee, while the number is 67% for Europe.
- Sustainable Business: ECommerce coffee usually runs on a subscription model. Therefore, you can build a sustainable dropshipping business.
And, here are drawbacks of the coffee dropshipping niche:
- Super Competitive: As we have mentioned, the global coffee market is dominated by established players and other famous private label brands.
- Hard To Promote: If you don’t have competitive advantages, it’s challenging to convince people to try your coffee products.
- Little Control Over Coffee Quality: Unlike clothing dropshipping, coffee beans are vulnerable to factors like temperature, weather, or seasons. And, you wouldn’t know if your suppliers suddenly deliver your customers low-quality and unfresh bags of coffee.
How To Start Dropshipping Coffee Profitably
To help you start dropshipping coffee profitably, we provide you with 7 tips and resources worth looking into.
1. Best ECommerce Platform For Dropshipping Coffee
We’ll recommend using Shopify for coffee dropshipping. The reason is that the platform is easy to use, fast to set up, stable, and effortless to scale up. On top of that, Shopify provides you with 21+ themes tailored-made for selling drinks like coffee and 4200+ apps to extend your store functionality.
You can also check out this article on how to start dropshipping with Shopify for more information.
2. Best Themes For Coffee Dropshipping
As we have mentioned, Shopify has a lot of themes. However, we think these 4 themes are the greatest for coffee dropshipping.
Express – Best Free Theme For Coffee Stores
Although Express only receives 30% positive reviews on Shopify, we think it’s still a theme worth trying out because of its uniqueness. It’s a one-page stylish store design theme made specifically for mobile devices, requiring little content and photography.
In addition, with quick buy and slide-out cart features, customers can quickly add multiple items without leaving their current page.
Editions – Best For Showcasing Coffee Dropshipping Products
Editions has a simple, clean, and spacious design, putting a heavy focus on showcasing your products. The theme also provides an infinite scrolling feature to let customers easily surf through all of your store’s items without leaving the homepage.
Editions currently receives 95% positive reviews and costs $100.00.
Blockshop – Best For Product Promotion
The next one is Blockshop. With multiple slideshows, homepage videos, and marketing popups, this theme is great for introducing your newest coffee products as well as promoting special offers.
Another thing we love about Blockshop is its full-width layout design. It gives you an excellent opportunity to impress visitors with high definition and large imagery.
Blockshop costs $180.00 and receives 96% positive reviews on Shopify.
Story – Best For Storytelling
Finally, we have Story. Living up to the name, the theme helps you capture your customers’ attention and tells your brand stories with a built-in timeline tool and story-focused product pages. Plus, you have a lookbook feature to display your collections in an editorial-style spread.
As of now, Story costs $180.00 and has 100% positive reviews on Shopify.
3. Store Design Tips For Coffee Dropshipping
Design components like color, typography, and graphics can greatly impact customer emotion and sometimes even alter their perception of your store.
Different colors mean different things and have different effects on the human brain. For example, you will often see technology companies like Paypal or Facebook use blue because it denotes professionalism and security. On the other hand, brands like Nintendo or Lego use red as it stands for passion and excitement.
For a coffee brand, black and white will trigger a sense of healthiness and cleanliness. You can also use brown to evoke a rugged and earthy mood.
With orange and yellow, customers will feel lively and energetic. On the contrary, use light blue if you want to exude freedom and tranquility.
Finally, green is great to signify growth and a connection to nature.
Typography is the next design element you should pay attention to. Similar to color, each type of font is suitable for a specific kind of business.
In the case of a coffee store, we recommend using display fonts with hard edges such as Bebas Neue, Righteous, Odibee Sans, or Special Elite for your logo and social media images.
With heading and body text, sans-serif or serif fonts are both fine. Examples are Meriweather, Roboto, Noto, Raleway, or Oswald.
You don’t need to use high-definition images for your coffee products as customers care more about the flavors and benefits your coffee provides or the functions of your coffee-related products. However, they still must be clear enough (at least 500 pixels x 500 pixels) to make your store look trustworthy and professional.
4. Facebook Ad Target Audience For Coffee Products
Facebook is the biggest social media network on the internet. With more than 2.74 billion monthly active users, it becomes the destination for over 200 million active businesses of all sizes and shapes to connect with customers.
Dropshippers also choose Facebook Advertising as the number one platform to promote their products. The reason is that it’s simple to use, powerful, and tailored to various needs. Furthermore, Facebook Advertising can automatically find all people with specified characteristics and scale with business goals on autopilot.
For the food & drink industry, the average conversion rate for Facebook ads can be as high as 3.98%.
When setting up a Facebook ad campaign for your coffee dropshipping store, audience targeting is one of the most important elements. Picking the wrong audience makes it hard for Facebook to find the right customers for your products. Choosing the same audience as competitors in your niche lowers your conversion rates as customers have alternative options.
Understanding the problems, we’ll present you with some tips for better coffee audience targeting.
Finland, Norway, Iceland, Denmark, Netherlands, Sweden, Switzerland, Belgium, Luxembourg, Canada, Australia, Germany, France, Italy, Brazil, United States (USA), Spain, Britain (UK), and Portugal are the top countries with the highest coffee consumption.
When you’re just getting started, you can create an ad campaign targeting all locations listed above. Then, run it for a few days to let Facebook figure out the best countries for your coffee dropshipping product. After that, you can create an additional campaign targeting specifically those countries to compare the performance between the two.
Ages, Genders, And Languages
Research shows that 34% of people started drinking coffee before turning 17, and roughly 70% did so before turning 25. More surprisingly, the level of coffee consumption only increases over time.
With the information, we recommend simply selecting 18 and 65+ for the age section of your Facebook ad campaign and let the algorithm do its job.
In regards to genders, 50% of men consume coffee compared to 32% of women. However, males typically spend less money on coffee than females. Therefore, you can just target both genders and again let the Facebook algorithm do the hard job.
For languages, choose one depending on your store language. For instance, if your store is in English only, choose English (All).
Target interests like Coffee, Coffee Bean, or Coffee Roasting are too broad. Plus, they’re super competitive as nearly every advertiser in your niche will target them.
Therefore, it’s best to go for more specific ones with an audience size of less than 2 million. We recommend White Coffee (1,511,500), Organic Coffee (1,276,740), Coffee Cake (1,136,790), Frappé Coffee (1,017,430), Coffee Milk (957,760), Fika (903670), Single-Origin Coffee (915,260), or Green Coffee (229,720). It’s important to note that your products have to possess similar characteristics as your target audience for maximum marketing effectiveness.
For coffee machines and coffee makers, Drip Brew (2,630,280) or French Press (953,270) are great alternatives for Coffeemaker (19,114,900). You can also do the same thing for other coffee-related products.
Remember to exclude Dropshipping from your ad campaigns to reduce the possibility of being spied on by other dropshippers.

5. SEO Keyword Ideas To Rank Your Coffee Dropshipping Store
SEO (Search Engine Optimization) is a crucial element for the success of eCommerce. According to a study, 51% of website traffic is driven by search traffic. Researchers also show that 40% of companies’ revenue is generated through search users.
Regarding buying behavior, 81% of customers do online research before making a large purchase. Additionally, 69% of mobile device shoppers are more likely to buy from a store that addresses their queries.
When you’re just getting started optimizing your coffee dropshipping store for SEO, it’s nearly impossible to rank for competitive keywords like Coffee, Coffee Maker, or Coffee Machine. As calculated by Ubersuggest, they all have SEO difficulty of at least 70, and websites ranking for these terms are all long-term and established ones, like Amazon, Target, BestBuy, or Peets.
We recommend aiming for keywords with an SEO difficulty of less than or equal to 30, such as Coffee addict (5,400 monthly searches in the US – 20 SEO difficulty), Caffeine Decaf Coffee (5,400 – 19), Coffee deserts (1,900 – 20), Clean a coffee maker with vinegar (5,400 – 14), or Japanese coffee maker (880 – 30).
You can also write articles to rank for question keywords like Is coffee a drug (2,900 – 6), How decaf coffee is made (2,900 – 7), Where coffee beans grow (320 – 7), Will coffee stunt your growth (210 – 7), or Where coffee comes from (210 – 6).
6. Building A Pinterest Profile For Your Coffee Dropshipping Business
Besides Facebook and SEO, you should also take advantage of Pinterest to drive traffic to your store.
Launched in March 2010, Pinterest was the fastest site in history to reach 10 million unique monthly visitors. Now, the platform has over 459 million monthly active users.
In addition to impressive user statistics, Pinterest is the number one social media in terms of social engagement. More than 40% of users earn at least $100K per year. Moreover, 66% make purchases after seeing a brand’s Pins.
Speaking of coffee, it belongs to the food & drink category, which is the 3rd-largest category on Pinterest and accounts for over 55% of all users.
Since Pinterest is a visual image search engine, you should aim to create coffee content that is not only Pinterest SEO friendly but also visually appealing.
Another important note is that Pinterest SEO shares some similarities with Google SEO. Hence, when you’re just getting started, it’s best to aim to rank for long-tail keywords as they’re less competitive. Examples are Coffee drinks at home, Watercolor coffee mugs, or Personal coffee mugs.
7. Tips To Increase Your Coffee Sales
Coffee subscription is the number one strategy almost every coffee dropshipping store uses to boost sales as well as customer lifetime value.
As straightforward as it sounds, your customers can choose to have their coffee automatically shipped to them on a weekly or monthly basis in exchange for discounts on each order.
Another way to increase your revenue is to cross-sell other related products like coffee mugs, coffee tumblers, coffee filters, coffee warming coasters, or affordable coffee makers.
We also often see many coffee stores expand their business by dropshipping tea.
