In Madeira, you won't be drinking Guinness but poncha, which is made from sugar cane rum and either orange or lemon juice. It's sweet and sour and a couple of them will make you forget your troubles.
Since we've been drinking it with folks from Scandinavia, we've been saying "cheers!" or skål!" rather than the Portuguese "saúde!"
But today we really should say, "sláinte!"
