Bob & Judith have come for the weekend, and I opened this as an aperitif (if you don't count the half bottle of wine that we 'tidied up' beforehand). I made them guess the ingredients and they failed miserably, with Judith running through all citrus flavours. When told, Judith and I agreed that rhubarb was prominent, though Claire said the dominant flavour was elderflower. Whichever, this was an excellent and refreshing wine. Bob said he thought it was about 13%, whereas everyone else gave it an eight out of ten.
