At its European production facilities, Germany-based Miele is continually walking the fine line between quality and efficiency when it comes to manufacturing luxury appliances.

But even within that juggling act, there’s still room for the finer things in life, which is why production workers at its Oelde, Germany, plant, where its cooking range is put together entirely by hand, always keep a supply of ladies hosiery within easy reach.

“We still use a silk-stocking test on the factory line for every machine that comes off,” says Kelly Lam, a vice-president of Miele Canada. “The assembly worker actually takes a silk stocking and runs it along and makes sure there are no rough edges or snags on the stainless steel.”

That attention to detail on its $20,000 flagship product, and the rest of its extensive product portfolio, which includes coffee machines, refrigerators and dishwashers is paying off. In its 2016-17 fiscal year, which ended June 30, Miele reported sales of €3.93-billion ($5.86-billion), a 5.9-per-cent year-on-year growth, with the majority of that (€2.75-billion) coming from overseas sales.

But while quality is important to everything manufactured by the company, which has been family owned and operated since its founding in 1899, financial considerations still have to be made. In one example, Mr. Lam says it would have been easy to look to offshore manufacturing in the production of its vacuum cleaners some years back to achieve certain efficiencies.

But instead the company built an entirely robotic production factory to manufacture the product at home.

“That allows us to still have the exact quality because obviously it’s completely controlled by us in Germany, but still allow us to hit some strategic price points in the vacuum category,” he says.

In Mr. Lam’s opinion, that insistence on quality is what is defining the luxury appliance sector. As a result, every product put on the market by Miele is tested to last the equivalent of 20 years of use.

“Nobody switches out their kitchen every five years,” he says. “It’s not a car lease or anything like that.”

Competing companies share this philosophy. Sub-Zero and Wolf, for example, utilizes extremes such as electric jolts and vibrations equivalent to a car crash at more than 72 kilometres an hour to ensure its own products can operate effectively for 20 years.

Customers have noticed. The kitchen appliance market globally was valued at $150-billion (U.S.) in 2015, according to Global Markets Insight, and expected to jump to $250-billion by 2023. Other research organizations, such at Trend-Monitor, say luxury items are helping fuel the growth, with their popularity rising “steeply” over the past 12 months. Canada’s buoyant real estate market and renovation craze promise to keep the trend going.

That customer appetite for quality and detail is why Marco Tallarico carries just a small number of brands at his Appliance Love stores, one in downtown Toronto and the other in neighbouring Mississauga. After-market care is partly why he chose the brands, which includes Miele, Jenn-Air, Sub-Zero and La Cornue, a handmade French brand of cookers which can range from $40,000 to $100,000.

“They’re very romantic, they have a story behind them,” Mr. Tallarico says. “People come in just for that … They’re just focused on this big significant piece.”

A focus on the appliances first, and then the remainder of the kitchen design, is exactly what Mr. Tallarico stresses to customers. It’s a philosophy that runs in his family; his father, Frank, owned Morley’s Appliance Centre in Toronto for 35 years.

“Design your kitchen with the appliances in mind, not the opposite,” he says. “Too many designers, what they’ll do is they’ll design the kitchen and say, ‘Go pick your appliances,’ after designing the kitchen. It shouldn’t be that way.”

With regards to trends in the industry, Mr. Tallarico says that increasingly customers are looking for smaller appliances, or appliances that offer dual functionality, such an oven that can offer steam and convection or speed and convection together. People don’t necessarily want the huge oven that comes into play only at Christmas and Thanksgiving, he says, and takes forever and a day to heat up. Speed is now of the essence.

“The customer is becoming way more savvy and way more sophisticated when it comes to cooking so they’re looking for the companies that offer this dual functionality and these are usually the higher-end companies,” he says.

While he says the majority of his customers want things that complement, or accentuate, their cooking skills first and foremost, some of the manufacturers that he carries offer innovative technology incorporated into their designs.
