WESTBROOK — When it first opened three months ago, Kassa Coffee in Riverbank Park didn’t have a logo, or even a credit card machine.

On the banks of the Presumpscot River, the small, white coffee trailer was quickly embraced by the Westbrook community.

“I don’t think I’ve ever seen this place once without a line,” a customer said while waiting for a coffee last week.

Iman Enan, the owner, said she owes it to the loyal customers who have supported the coffee trailer through word of mouth and social media.

Kassa Coffee brings something different to Westbrook, Enan said. She’s proud of the high-quality matcha and the creative flavors they offer.

And it’s the presentation of the drinks that have made them so popular on social media: “Come with me to try Kassa.” “Finally stopped by Kassa Coffee after hearing so many great things.” “Today, I’m trying a new coffee shop in Westbrook,” are a few of the posts.

On social media, people document their trips to the trailer. They twirl their straws, pose in front of the trailer, take a sip, and share reviews from their cars.

One customer told Enan she heard about the coffee trailer from her daughter, who lives in New York and somehow came across a video about Kassa Coffee. Another customer came down from Lewiston just for the coffee.

Enan moved to Maine from Iraq when she was a teenager. She attended Deering High School and studied psychology at Southern Maine Community College and the University of Southern Maine. Her last year of college was remote, so she spent most of her time studying in different coffee shops, constantly surrounded by the smell of coffee.

“Coffee shops were like my home,” Enan said.

Opening her own always felt like an unrealizable dream, until she got laid off from her job as a case manager. Her husband told her it was an opportunity to follow her dream of making coffee.

When Enan’s husband bought the trailer, it was more like an ugly, red, empty metal box than anything resembling a coffee trailer. It took four months for him to turn the box into a functioning business.

Inside, it’s very simple: a coffee machine, a fridge, a sink — all secondhand.

It’s a tiny business, Enan said, just her and her husband, and her sister who helps out after school.

Enan makes the coffee, which she learned from working at Starbucks for a few years and from watching people work in coffee shops. Her husband does all the math, drives the trailer to the park every morning and makes drinks.

Many customers have asked them to open up a coffee shop year-round or to come to different areas, but commercial spaces are expensive, and their license restricts where they can work, she said.

They’re exploring different possibilities for the future — such as closing down for the winter — but for now, they’re open 8 a.m. to 6 p.m. every day except Wednesdays.

“We’re trying to build community here,” Enan said.

The proximity to the park’s playground is good for business, and it’s convenient for Enan, a new mom. The couple doesn’t have a babysitter, they just take turns taking care of their 18-month-old daughter while taking orders and making drinks.

Running the coffee trailer feels like raising a second baby.

While Enan feels very lucky the business became successful so quickly, it wasn’t without its challenges.

On the first day the trailer opened, a man began harassing Enan and making racist comments.

“You’re taking over the park. You’re too loud. You shouldn’t be here,” Enan remembers him saying.

On the second day, he called the police. A few weeks later, when he came back, Enan offered him some coffee. He told her she didn’t belong here.

He returned again one day when customers wearing head coverings were ordering coffee. He screamed at everyone to get out of the country.

Enan talked about the incident with a customer who happened to have a large following on TikTok, and the customer posted a video about it. The video got a lot of attention, and news of the coffee trailer spread on social media.

The following weekend, there was such a long line in front of the coffee trailer, Enan was overwhelmed by the support and cried.

Afterward, she decided not to talk about the incident anymore. She appreciated everyone’s support, but she didn’t want her coffee trailer to be known for that. She didn’t want to be known as a victim of racism.

“I want people to like us for the coffee, not because they feel bad for us,” Enan said. “I want to represent my business as a Muslim woman that serves something good.”
