Despite hailing from Adelaide, over the past 30 years McKenna has forged a reputation for being one of New Zealand's greatest winemakers, and it's his international success producing premium pinot noir that's earned him the moniker "Larry McPinot" or "Mr Pinot Noir".
Cutting his teeth on pinot back in 1986 as the winemaker for Martinborough Vineyards, he catapulted the company to international stardom when its 1998 Martinborough Reserve Pinot Noir - which he crafted - won a place in the World's Top 20 Pinot Noirs competition held in the US last year.
McKenna also established his own operation, Escarpment Vineyards, in 1998 with three other directors on Martinborough's rocky Te Muna river terraces. Te Muna translates to "secret" or "special" place and with its sweeping kilometre-long escarpment and vertiginously steep 30m drop to the river, it's an incredible site.
Under McKenna's eye for eking excellence from the soil into the vine, the vines are planted very close to one another (6700 vines/ha) and produce a minuscule 1kg of fruit per vine which, if you do the maths, is roughly one bottle per precious plant. Despite firmly believing Martinborough to be the location of his pinot noir-vana, during the development of Escarpment, Larry spent time as a consultant to pinot noir producers around New Zealand and Australia just to keep his hand in the multi-regional mix.
Anyone in the wine business will tell you that good pinot noir is notoriously difficult to make. Even if you have the best site in the world it's a variety that, despite being one of the sexiest, most beguiling wines you'll ever come across, can curl up into a moody, thin-lipped, weedy nightmare if you're not careful, which is why I so admire what Larry manages to produce.
Not content with the stress of trying to create just one or two great pinots from his vines, McKenna makes five.
In only the exceptional years since 2006 "the pinnacle of our winegrowing achievements" is bottled under his Insight Series label.
Designed for time in the cellar, tiny quantities of these wines are crafted from each of his single vineyard sites, and help to explain his passion for expressing the individual "terroirs" of the Martinborough region.
On March 1 he released his famous five from the 2010 vintage which, according to McKenna, was an exceptional year in Martinborough.
The Escarpment "Kupe" Pinot Noir 2010 ($85) is deeply dark and inky with a core of vibrant rhubarb, clove, cherrywood smoke and wild strawberry characters. Fresh acidity adds a layer of lush, textural intensity to the finish. It's a sexy, succulent wine with a huge future.
The Escarpment "Kiwa" Pinot Noir 2010 ($65) has baked strawberry, redcurrant and sweet oak aromas on the nose and boasts a lovely mid-palate presence and a deliciously spicy, tea leaf note on the finish.
The Escarpment "Te Rehua" Pinot Noir 2010 ($65) boasts ripe, juicy japonica and cherry notes and I love the multi-dimensional, slippery, silky mouthfeel of this wine. Hedgerow fruit, spices and a hint of cocoa make this a superb sip, indeed.
If you want to be completely seduced by something then try the Escarpment "Pahi" Pinot Noir 2010 ($65).
A mouthful of this wine is like tasting a handful of ripe, black cherries freshly squashed between dust-covered fingers and smeared over something old and leathery (not Joan Rivers old-and-leathery but a seasoned, weathered satchel strapped to a cowboy's saddle). It's a magical wine that offers plush, succulent fruit, spicy complexity and impressive persistence of flavour.
Finally, the Escarpment Martinborough Pinot Noir 2010 ($49) is a multi-site, district-blend which shows lovely soft plum, cherry and berry flavours sewn together with vibrant, tangy acidity to create juicy length and definite drinkability.
McKenna's wines are a reflection of his passion and pedigree, but his personality is anything but posh as I found out while standing at that smorgasbord all those years ago.
"Hey, Yvonne," he whispered in my ear, "when you're done with that shank bone would you mind chucking it on my plate? I'm gonna wrap up as many as I can bludge in some tinfoil and take them home for my old dog."
We've been firm friends ever since.
