The range includes a high cocoa content, lower sugar milk chocolate.

An artisan chocolate business near Norwich has just launched eight new single origin bars.

Produced using premium, ethically-sourced beans, the bars from Saffire (based in Taverham) include a milk chocolate with one of the highest cocoa contents in the UK.

Angela Ruthven, the creator behind Saffire (known for its truffles, bars and novelties) said of the new range: 'After 12 years in business we decided to shake things up a bit. We have always tried to be ahead of the market and this is where we think we are with our new range of single origin chocolate bars.'

Each of the eight bars has been decorated individually by hand so no two look alike, and they've been cast in specially commissioned Union Jack moulds.

'We are delighted to be able to introduce our customers to a new chocolate experience,' Angela continued. 'All single origin chocolate is limited in availability and is only 5% of the world's chocolate. We have chosen this small range because the chocolate has all been fairly traded and also theses are the chocolates we like the best – so they come highly recommended.'

In the range is the Columbian 65% Dark, using cocoa from the slopes of the Andes, and with tasting notes revealing hints of vanilla and rich fruits.

The Equadorian 70% is on the bitter side, with elements of tea and a sour bite.

And, in good news for milk chocolate lovers, the Madagascan 65% Dark Milk is a smooth creamy chocolate with a high cocoa content but less sugar than a typical 80% dark chocolate bar!

These single origin bars are only available in store in Taverham or on the Saffire website.
