Research seeks to tap into craft-brewing potential of Maritime wild hops


4 minute read

HALIFAX — Two federal research scientists are working with varieties of wild hops found in the Maritimes to see if some of their unique aromas can eventually be incorporated in craft beers.

Jason McCallum and Aaron Mills have spent the last two years searching out wild hops that grow mainly along creek beds and heavily forested areas in Nova Scotia, New Brunswick and Prince Edward Island.

McCallum said in addition to the native wild hops, there are also hops varieties from Europe that have flourished since their introduction by settlers during the early colonization of North America.

As a result, the plants grow relatively abundantly and are easily recognizable to someone who knows what they are looking for.

“Just driving around you can spot it in your car at 80 kilometres an hour …. Some of the sites we found were just through random road scouting like that,” McCallum said.

The plants can be quite tall — growing as high as 10 metres — and they can be found climbing up dead trees, utility pole guide wires and bridge embankments. Their leaves look similar to grape leaves.

“We often found the hops growing up apple trees on old farmsteads,” Mills said.

The pair found more than 60 different wild-growing hop populations and subsequently planted samples at Agriculture and Agri-Food Canada’s Harrington Research Farm near Charlottetown.

They’ve since been researching the chemical composition of the varieties to determine their origin and to see which hold promise for the brewing industry.

McCallum said a particular attraction for brewers are bitter chemical compounds found in the plants known as alpha acids. The native variety that has evolved solely in the Maritimes has shown the most unique potential he said.

“All of the Maritime (native) stuff has adequate alpha acids for brewing purposes. But one thing that really stands out about them is that they have very unusual smells and flavour characteristics.”

McCallum said that once dried and rubbed together, the plant’s flowers produce such smells as melon, cucumber and even bubble gum.

Mills said the research is now moving into a second phase that will eventually see the hops move from the federal farm to commercial breeders.

But first the researchers have to figure out such things as the plants’ yield potential and resistance to disease.

“The craft brewers will take anything and brew with it if there is a story attached to it,” Mills said. “But we want to make sure that the quantity is consistent and we have a handle on the flavours.”

Data will be submitted over the next two years to the Canadian Food Inspection Agency’s Plant Breeders Rights Office, which provides legal protection for new plant varieties. McCallum and Mills also plan to work with producers across P.E.I, Quebec and British Columbia to see if the Maritimes’ wild hops varieties can be grown in other parts of Canada.

Mills said if everything goes as planned, the first plant material could go to commercial partners for planting in another two years. After that, it could take a few more years before beer incorporating the hops appears on local shelves.

McCallum said they believe they have found something that could potentially provide brewers in the Maritimes with some intriguing new products in an industry that embraces novelty.

“With the craft brewing revolution in North America, it’s kind of the wild west in what’s the craziest thing you can come up with that’s new, and people kind of chase that,” he said.

Why Canadians Should Care About Land Loss

Why Canadians Should Care About Land Loss

Developments are increasingly taking over Canadian farmland. Farms once took up much of Canadian land. However, that case is not true today. Only about 5% of Canada’s land is considered prime farmland. This prime land borders one of Canada’s fastest-growing regions, and once suburban development overtakes it, Canadian farmers will have a challenging time providing food for the cities.

Farmers in Canada make their livelihood by planting, growing, harvesting and distributing food to the Canadian populations. Without land, both farmers and the rest of those living in Canada will not get fresh, Canadian grown produce.

Here are some reasons why Canadian farmers should care about land loss:

  1. Farmland Provides Food

While this is an apparent reason, it’s an essential one. Prime farmland in Canada produces food for major Canadian cities. As farmers continue to lose land, they have to rely on a smaller acreage to make the same amount of food — if not more — for the growing population.

Over the past 10 years, almost 1 million hectares of agricultural land has diminished due to development and growing populations. Agriculture continues to adapt to land loss. However, further technological advancements must first take place to grow enough produce vertically rather than horizontally.

  1. Land Preservation Will Help the Economy

Farmland preservations come with a wealth of economic benefits. Agriculture contributes to the economy through the following ways:

  • Sales: For the economy to survive, there needs to be consumer demands and sales. Almost everyone purchases produce, so there will always be a demand for those goods. Without land to grow agricultural products, no sales will be made, and the economy could suffer.
  • Job opportunities: Less than 2% of Canada’s population works in the agriculture industry. While it’s not much, that’s still over 750,000 people. Preserving farmland shows a commitment to the industry. Land loss would create job loss. However, maintaining the farmland — and even reclaiming it, along with pastures — could boost the sector and, therefore, the economy. It would provide unemployed people with job security.
  • Secondary markets: Farmers are just one part of the food business. Because of farmers and farmland, secondary markets can thrive. These would include processing businesses, restaurants, schools, grocery stores and even waste management companies.

Canadian farmers should care about land loss because standing back and allowing companies to overtake the farmland could seriously affect the economy.

  1. Farmland Benefits the Environment

Wildlife often depends upon farmland for both food and habitat. Various types of farmland create diverse habitats for many different species. Without land protection, these habitats and food sources would be destroyed, leaving many animals without a place to survive. Many would have difficulty finding a native habitat.

Additionally, growing crops helps eliminate some of the carbon dioxide released into the air. Air pollution could decrease for Canadian cities as long as no more farmland is used for development.

One major problem occurring with Canadian farmland is desertification. This happens when the soil loses nutrients and becomes barren. The urbanization of Canadian farmland is the primary contributor to desertification, which speeds up climate change and harms the environment. Keeping farmland as-is will slow down climate change.

  1. Land Loss Affects Farmers’ Jobs

Perhaps the main reason why Canadian farmers should care about land loss is because their livelihood could be taken away. If they don’t have the means to keep up with technological advancements in the agricultural industry, they will not be able to continue their jobs if they experience land loss.

Agriculture is an essential industry. Not everyone can pick up the skills needed to grow their own food, and so many people depend upon farmers for nutrition and goods.

Take a Stand to Preserve Farmland

Farmland is a worthwhile and precious resource for many people. Reduction in farmland acreage will hurt Canadian farmers and the rest of the population, the economy and the environment. Taking steps to prevent more land loss can slow the rates of destruction and keep natural habitats thriving for both humans and animalls.

Canadian Agriculture More Energy Intensive, More Efficient

Canadian Agriculture More Energy Intensive, More Efficient

It’s no secret that agriculture has contributed to climate change through various means. For example, you may know that livestock generates greenhouse gas emissions due to how farms process it. That said, it’s now clear that farmers have found sustainable ways to offset those contributions. In Canada, it’s all about energy use.

Here’s how Canadian farmers have become more efficient as they raise crops and livestock, setting a standard the world should follow.

Energy Demand and Consumption Have Fluctuated

The demand for energy has increased across the agricultural sector as a whole. However, it’s key to note that farmers have begun to use less energy despite that fact. That points to more efficient practices. The farmers who complete their work productively save time, money and energy. As a result, Canadian workers have reduced their energy consumption per dollar by 17%. That’s thanks to sustainability.

The most common energy sources include fuel, gas and electricity. It’s how farmers use those resources that counts. Combined with technology choices and new practices, it’s clear that efficiency is more achievable than ever.

What Contributes to This Phenomenon?

It’s crucial for people in agriculture to explore eco-friendly alternatives. The grasslands that many western Canadian farmers cultivate contains excess carbon, so you can imagine what the country as a whole holds underneath its surface. Farmers have now adopted new methods to adjust how they harvest their crops. These systems are better for production, as well as soil and seed health overall.

The agriculture industry has gone through many changes, too. There are fewer farms — but those that still operate have employed agricultural technology to be as efficient as possible. These tools include different equipment that cuts down on time to increase proficiency. Plus, it’s now more common to use solar power as an alternative to traditional energy solutions.

Why Accuracy and Precision Matters

It’s a lot easier to be energy efficient when you don’t waste your resources. The means farmers practiced before they used specific innovations often created a time deficit. If you have a smaller machine, you likely need to do twice as much work. However, when you have access to equipment that fits your field, you don’t have to be as wasteful. The accuracy and precision created by technology make this a reality.

Soil Conservation Is Led by Ranchers

Many farmers have looked to ranchers for help. It’s a native part of ranching to preserve topsoil and other elements that are inherently sustainable. As a result, it seems like ranchers have been leading the charge against climate change for decades. The tactics they use to avoid tilling soil, for example, help preserve the amount of carbon that lies underneath the Earth’s surface.

The “no-till” practice is efficient in its own right. Rather than till your soil to plant a new crop, you simply leave behind what’s already there. This method is much better for soil nutrition, and it can keep carbon exposure at bay. As a result, you have much fewer carbon emissions. In general, the idea of soil conservation isn’t a new one, but old tricks can still work alongside modern technology.

The Future of Agriculture in Canada Looks Bright

If farmers continue on this path, it’ll be clear that climate solutions are at the forefront of their minds. These efforts create more benefits for them as they save time and money. Plus, there’s always the responsibility of maintaining the planet’s health. After all, without a strong ecosystem, agriculture would suffer. Through means that are more accurate and conservative, Canadian farmers have been able to become more efficient. Click here read more stories by Emily Folk.
