Read over all the instructions before you begin, then, when you have all the supplies to hand, have fun making mead. Reasonable cleanliness and accuracy is all that's required, not laboratory precision. The supplies you need for mead-making are easily obtained, even if there is no homebrew shop in your immediate vicinity. Try your nearest Boots for the demijohn, rubber bung, airlock, siphon, Campden tablets, acid blend, yeast nutrient and champagne yeast. You could make mead the old-fashioned way with just honey, water, and yeast, but it would take several years to mature and lack complexity of flavour.
Yeast nutrient helps the yeast to ferment more quickly.
The acid blend gives the finished mead a subtle fruitiness and balanced taste. When purchasing honey for use in mead, the important thing to keep in mind is that bland, tasteless honey makes bland, tasteless mead. Locally produced honey from a farmshop varies in flavour and quality depending on where the bees get their nectar. Some is very good indeed and some is less tasty than cheaper supermarket honey. Try it on your toast before you use it in your brew.
