Harnett’s Oils

Northern Ireland has the ideal conditions for growing oilseeds. The Harnett family know that. That’s why the fields on their County Down farm are worthy of a Van Gogh painting when the crops are in flower. They grow oilseed rape and hemp, then cold press them and bottle them all on site.

These golden-hued bottles of loveliness are so healthy, it (doesn’t) hurt. We’re talking oodles of Essential Fatty Acids in the perfect ratio for the human metabolism as well as vital vitamins and terrifi c trace elements.

Usually things that are so good for you don’t tend to taste that great (wheatgrass shots, anyone?). Happily these are as nyummy (OK I made up that word, it’s more of a sound) as they are nutritious. Mix up a salad dressing, use the hemp oil as a dip and cook and marinade with the rapeseed oil. They can be used in a wide range of ways; as salad dressings or dips for the hemp oil and as a quality cooking oil or marinades for the rapeseed oil.

The Harnett family have also diversified into award-winning artisan sea salt under the brand Duvillaun Fine Foods.
