I'm told that 12 beers equals half a loaf of bread.
On the whole I favour coffee/water. Pity the water at my new place tastes kak. Still need to install that filtration system thing...
You should try Oasis water. R160 for a 25l canister and then R1 per liter to refill... We started buying it after we realized the water at our new place tasted way too metallic.
