Thats the Asian variety that uses Pyrazine. The native variety may be perfectly fine. Taste test it.

I am a great fan of Fer Servadou in Marcillac and elsewhere. However, in the San Juan Bautista area, it is just a pyrazine extract. Maybe suitable for inclusion in a recipe for pickled beets.

👋 Our new paper in @natchem.nature.com shows a molecular ferrimagnet that produces almost no external magnetic field and persists well above room temperature.🧲🌡️
Cr(pyrazine)₃ is a simple metal-organic framework with magnetic interactions comparable to the strongest known in inorganic materials.

Lunch at Les Antiquaires in Perpignan today. I took advantage of the fact they had wines outside the area and ordered this Pinot Noir from the Loire Valley. Very soft tannins, typical PN taste though with some pyrazine (green bell pepper) in the finish.

3-Isobutyl-2-Methoxypyrazine (IBMP) (2-methoxy-3-(2-methylpropyl)pyrazine) is an almost unavoidable but invariably detectable component in Sauvignon Blanc and Cabernet Sauvignon wines ... as creating the green bell pepper, pea, or asparagus aromas, with an astonishingly low detection threshold.

Excited to share a latest preprint on an ytterbium-pyrazine square! In this work, we provide evidence of charge transfer from Yb(II) to pyrazine, supported by a range of techniques.
Notably, this complex also shows solvent-dependent reversible electron transfer.
