"Owing to the difference in climate, wines that taste austere in Jerez taste even more austere in the northern countries, and the further north you go, the more you notice it: you can even tell the difference after a journey from London to Edinburgh. One shipper claims that a trace of sweet wine in a fino merely robs it of this excessive austerity, and that his slightly sweetened fino tastes the same in London as the natural wine does in Jerez."
