<pre>Can anyone provide any background or history about these two Italian
cultivars: Bosana & Madonna dell'Impruneta? It's my understanding that
Bosana is Sardinian and Madonna dell'Impruneta is Tuscan.

Thanks

Yes, Bosana is Sardinian, that's for sure. We had data from quite a lot of
Bosana from Sardinia to examine, a few years ago when I was carrying out
data analysis on different italian varieties. Most of the Sardinia samples
(maybe all - I'm not sure) were Bosana. There were no Bosana from elsewhere.

Not surprisingly, being a native variety to Sardinia, we were able to
distinguish Bosana oil from other varieties with our instruments. I don't
know how the taste may differ, though.
