The article seems less about the toxicity of the cesium levels, and more about their use as a signature in dating the wine, which I find is still interesting.

And rightly so, by far the most toxic thing in these bottles is alcohol, not vanishingly small traces of cesium.

If the bottle was sealed, it won't pick up measurable cesium. That arrives via atmospheric transport, being picked up by rain water and eventually grape plants.

> So nothing to see here, move along.

The unit of measure in this are mBq/l; millibecquerel per liter. The paper reports 14 mBq/l in CA wine immediately after Fukushima. So the common 750ml bottle of 2011 CA wine will average one cesium-137 decay event every 53.5 seconds.
