It only produces 0.7 per cent of the world's hops. Two varieties that have been barnstorming the British beer scene make up less than ten per cent of that crop. So how the hell did New Zealand begin to punch way above its weight in the hop world?
Hops have been in-country since arriving with European settlers in the mid-nineteenth century. Nelson province on the South Island became the industry's cradle, benefiting from a temperate climate, high number of sunshine hours, regular rainfall and relatively wind free conditions. The imported varieties were moderately successful, but the industry was transformed by the introduction of an West Coast American hop in the 1920's.
'Late Cluster', known in NZ as 'Cali', offered better growth and greater yields and became the hop crop of choice. But twenty years later, Cali was crippled by a soilborne root rotting disease, phytophthora, and the country's hop industry was in dire straits.
The response was the establishment of the Hop Research Station at Riwaka in 1949. Tasked with breeding new high-yield varieties resistant to phytophthora, three cultivars were developed (Smoothcone, First Choice and Calicross). By the mid-sixties when these hops were well established, the industry faced a new challenge.
Lager's growing popularity boosted the worldwide requirement for seedless aromatic hops. Whilst Europe was busy eliminating the seeded male hop plant, New Zealand took a different tack. They developed a virtually sterile seedless plant that still retained the aroma and bitterness characteristics of its lineage. The varieties produced (Green Bullet, Harley's Fullbright, Sticklebract and Super Alpha) became the world's first commercially produced triploid hops (ones having three chromosomes).
Further developments saw New Zealand carry out extensive research into aroma cultivars that were adapted to the country's growing conditions. Out of that program came New Zealand Hallertau, currently the most-produced hop in the country at 42% of the total acreage.
Hop production trebled through the eighties and nineties, and today over 80 percent of the crop is exported. But it's still responsible for less than one percent of the world hop trade. Perhaps the true value of its contribution can be found in two unique offerings.
Less than four percent of New Zealand hop production is of the varietal Nelson Sauvin. But, what a hop it is. Released in 2000, it offers an unmistakable aroma of gooseberries that's almost identical to that of the Sauvignon Blanc grape (hence the varietal's name). It's used by British brewers such as Brewdog to enhance the complexity of pale hoppy beers such as Punk IPA. Thornbridge showcase the hop to incredible effect in their South Pacific Pale Ale, Kipling. It's a hop whose impact can only widen as more drinkers experience it and fall in love with it.
There's also major potential for the production of organic hops. With typical viral and fungal hop diseases not an issue and the only significant pest (the two-spotted mite) controlled by a predator, no pesticide use is needed. Nor are herbicides - instead there's a well-engineered solution that both clears foliage around the hop bines whilst depositing natural organic fertiliser at the same time. It's called sheep grazing.
Unique varieties and organic credentials ought to make New Zealand an expanding player in the world hop market. The cost of freighting the end product out internationally may be the major obstacle to rapid returns on export. But when it results in beer that offers a real 'wow!' factor, perhaps it's a price well worth paying.

Now, I wouldn't usually bother with the likes of a CAMRA festival in Coventry. But this trip had several factors in its favour; a direct train service from Derby, an interesting venue (Coventry rugby club) and the chance to meet up with some of the England Ratebeer.com crew.
It was a gorgeous blue sky morning, so with an early arrival into Cov I set up off to the cathedral for a spot of photography and a trip up the old tower. All 180 steps to the top where you're rewarded with a sobering view of the bombed out shell of the old cathedral. And a view of the multi-story IKEA, where (apparently) devout flatpackers flock on a Sunday morning...
With my heart beating its way out of my chest, I decided a beer stop was in order. Fortunately, there was a Spoons/Lloyds close by, the Earl of Mercia. As well as intermittent free wifi, I got the 'other' foreign-brewer-brewing-in-the-UK-Spoons-fest beer, Tokyo Yoho black. Which wasn't that great - if I hadn't seen it come out of the cask, I'd have questioned whether they'd given me extra cold Guinness.
So, after a tramp around Cov's exquisite ring road (having asked a policeman the way) I found the rugby club. And a fine place it looked, too. Sadly, there was no drinking in the stands which I thought might have been the case.
It was a busy place, a cram of tables in one room and a stillage in a room further along. Getting warm , too - more about that later. Ratebeer stalwart Glen from Oxford was already there and had secured a table. Mark and friends had made the trip up from Northamptonshire and were there too, busy tucking in to some decent ales.
And those ales - some -though not a lot of - fun local beers (Discovery Darwin's Delight was probably the best), good beers from further flung parts (Dark Star Over The Moon) and the occasional standout (Fullers London Porter, Leyden Raglan Sleeve). The beer of the fest for me, though, was Alehouse Sauvin So Good; good to see the Nelson Sauvin hop being used more (as it is to stunning effect in Thornbridge Kipling).
Whilst at the bar, I spotted a familiar face; Mes and Sim without the Sim. He'd blagged a trip in the Phil L beer taxi. Always good to share a few beers and more than a few laughs with him, particularly as he never fails to remind me how good my ratebeer review of Full Mash Drizzlecombe Porter is ;-)
As for Phil L; first time I'd met the man and what fun it was - a genuine, knowledgable, affable guy who knows his onions but doesn't ram them down your throat. If you see what I mean. And, what's more, he brought a couple of bottles to share round the table; Dragonmead Final Absolution (a US Belgian-tripel style) and my first Finnish beer, the incredibly moreish Mikkeller Santas Little Helper.
So, a fest of fun? Just. The venue was OK; a little cramped perhaps and certainly on the warm side. Just before kick-out time (4pm) the beers were getting decidedly warm. The loos worked most of the time. Access was on the level but it was a bit of a struggle for some wheelchair users as everywhere in the place had drinkers dripping off the walls. I didn't try the food (as I did take a Walter Smith pork pie) but the trays of chips seemed to be going down well. And it was a bit of a hike in the wrong direction from the rest of the city.
Let's be clear - it needs a bigger venue (or perhaps a marquee on the pitch after the season's finished). But the beer list was interesting and the ratebeer company was as fun as ever.
Will I be back? Get some coolers on the casks, let us sit in the stands, get Phil L to smuggle some more foreign beers in and I'll seriously think about it.
