Certain differences are immediately noticeable between France and the UK; the most obvious being the price of wine.
For our everyday throwing wine, I tend to buy it in boxes. There are two main advantages to this, firstly the wine stays fresh for well over a week (if it lasts that long), and secondly I don't end-up with piles of empty glass bottles. The wine itself is also perfectly acceptable.
However, the price is very different on either side of the Channel. In France I buy 5 litre boxes at just under €10 (about £7.30), and here I buy 3 bottle boxes (2.25 Litres) for £13.50.
Yes, 5 litres for £7.30 in France, and 2.25 litres for £13.50 here in the UK. WHY? Less that half the quantity in the UK for around twice the price!
It's exactly the same product, there is no shortage, and its transport is no different to anything else.
Well the answer is very simple; it's tax. In the UK the greedy tax folk take 14.5% tax and another 20% VAT on all wine over 11 degrees. This excessive, and you can guarantee that it will rise again with every budget.
