Sorry to say, but you had really terrible Latin teachers. There's simply no way that the first i in Plinius can be pronounced like an English long i sound, simply because the latter sound is a diphthong, and Latin speakers never represented diphthongs with a single vowel. Even in English that sound could never be achieved with a single letter until after the Great Vowel Shift in the 15th century: when Chaucer wrote "I" in the 14th century, he rhymed it with the modern English "tree." In classical Latin the first syllable of Pliny, as (mis)pronounced by Vinny Cilurzo and those who chose to emulate him, would have been spelled Plae, not Pli. One could reasonably dispute whether the first i should be pronounced as a short or a long vowel, i.e. "ih" vs. "ee", but it can never become a diphthong. So, to sum up: there's no controversy over how to pronounce the Anglicized name of the historical figure - it's with short i as in, well, "in." The only reason to pronounce the beer differently is the fact that its brewer was ignorant as to the accepted pronunciation of the historical figure after whom he named the beer. Personally, I don't feel that Vinnie's ignorance should take precedence over centuries of accepted pronunciation, and that if he wants to capitalize on an existing name he should be humble enough to admit his mistake and pronounce the name correctly. If he had genuinely made up the name, then he would have the right to dictate its pronunciation; he chose to name his beer after a preexisting figure, however, and thereby gave up his right to decide how it should sound since his creation came after the creation of the name. So much for my subjective assessment of the matter; of far greater importance is the fact that this dispute doesn't matter in the least, and anyone who gets upset about it on either side is a pedantic asshole. You say Ply-nee, I'll say Plih-nee, and if you have the decency not to "correct" me I'll have the decency to do the same. Either way it's delicious! Cheers!
