A report on Wikipedia implicates varieties of pine from China.

Risks of eating pine nuts
A small minority of pine nuts can cause taste disturbances, developing 1–3 days after consumption and lasting for days or weeks. A bitter, metallic taste is described. Though very unpleasant, there are no lasting effects. This phenomenon was first described in a scientific paper in 2001.[12] Some publications have made reference to this phenomenon as "pine mouth".[13] This is a relatively newly noticed phenomenon. The Nestle Research Centre has hypothesized that a particular species of Chinese pine nuts is the cause of the problem. The suspect species of pine nuts are smaller, duller, and more rounded than typical pine nuts.[14] This agrees with the findings of fødevarestyrelsen (Danish food ministry), which ties the symptoms to "illegitimate" nuts from Pinus armandii (Chinese white pine) and Pinus massoniana (Chinese red pine), which have a different fatty acid than "genuine" pine nuts, being mixed with "genuine" pine nuts in China to meet export demands.[15] Metallic taste disturbance, known as metallogeusia, is reported 1–3 days after ingestion, being worse on day 2 and lasting for up to 2 weeks. Cases are self-limited and resolve without treatment.[16]
