Costco shifts again on sourcing olive oil

After little more than a year of using olive oil from Greece for its Kirkland Siganture extra virgin olive oil, warehouse giant Costco has apparently switched back to Italy as the source for its green-gold elixir.

Costco switched to using extra-virgin olive oil (EVOO) from Greece for its private-label 2-liter bottles last year after the disastrous 2014-2015 harvest — plagued by bad weather, pests and wasting diseases — that saw Italy’s production plummet and prices soar.
