First of all congrats on your blog/site/podcasts. Great stuff with lots of interesting information.
Nevertheless, there's a mistake in your text when you say that "In the Alentejo region of southern Spain". I'm sure you wanted to write "Portugal" (or "Iberia"), instead of Spain.
Btw, in portuguese, "Bastardo" is an illegitimate son, but I don't know if the grape name is related to that.
