Koshu

 

            Beaujolais Nouveau still had a following in Japan when I lived there. The rest of the world had had enough, but the glory days hadn’t yet ended in Japan. I remember going to a British pub in Kyoto one December, shortly after the release of the latest Nouveau, and asking the Japanese bartender if they had a red wine other than Bo-joh-reh. Sorry, but no, was the answer. They did have Beaujolais, of course, but that was it. I declined and had a beer.



While Beaujolais Nouveau was worthy of a large sales display in convenience stores like Lawson and 7-11, nobody ever mentioned to me that I ought to give the Japanese grape Koshu a shot. It could be that I was simply moving in the wrong circles, in which beer, plum wine and shochu (a fearsome and, to me, mysterious spirit) were the kings. Then again, maybe it just wasn’t very well-known.

            Almost a decade after leaving Japan, I finally decided to see what Koshu was like. I did a modicum of research and learned that the grape is associated with Yamanashi prefecture, the location of Mount Fuji, so it is unsurprisingly well-adapted to volcanic soils. It’s also disease resistant, which is a real plus point. I spent a year in Shizuoka prefecture, which shares Mount Fuji with Yamanashi, so I can speak with authority on this matter. The rain in that part of Japan could be like something out of The Old Testament and the humidity was intolerable in the summer. Not ideal conditions for growing vines, in short.

            It’s not that easy to obtain Koshu in the U.K. They don’t even have one at Majestic Wine, for goodness’ sake. The first bottle I sampled was a 2011 Koshu ‘Sol Lucet’ from Yamanashi Wine Co., which I optimistically purchased online about fourteen years after the vintage. It had a very dusty shoulder and cap, and a wonky label on the front. Not promising. ‘The characteristic parts of this wine are Japanese citrus notes’, I read on the back label. The flavour was in fact indescribable, and the bottle probably should have been drunk a decade before I opened it.



            Next up was Château Mercian’s Koshu Gris de Gris 2022. I’m not generally partial to orange wines, as I find it hard to get my head around the concept of a tannic wine made from white grapes. More importantly, the flavours are often just plain odd. If it doesn’t taste weird, I think there’s a strong chance that an orange wine will taste of apples – baked, most likely, or something akin to a carton of apple juice. Such was the case with this wine. It was pleasant, but when the bottle was empty I was still scratching my head about the varietal character of Koshu.



            I finally tracked down a bottle of Koshu which had undergone a standard steel fermentation and was not past its best in the handsome cathedral city of Lincoln. As I climbed an empty street appropriately called Steep Hill, I saw a wine shop. I was shocked to see a bottle of Koshu in the window, as well as a bottle of Springbank 10 Year Old Campbeltown whisky. This had to be a good place.

            I went back the following morning and bought a bottle of Grace Wine’s Kayagatake Koshu 2023. Alas, I found the wine underwhelming. I concurred with the producer’s tasting note in so far as it had ‘lively acidity’, but it was a rather neutral wine. I picked up a touch of green apple and my tasting partner felt there was a chamomile note, but that was about it. Even more disappointingly, the shop didn’t have any older Springbank whiskies.

            Earlier this year, I almost bought a ticket to London in order to attend a tasting devoted to Koshu. In the end, the Scottish side of me won, and I went to Campbeltown instead. I’m aware that I didn’t try very much, but if I ever go back to Japan, I don’t envision myself seeking Koshu out. Give me a glass of plum wine on the rocks instead.
