Giving Organic September the green light and choosing to buy organic wines not only takes the guesswork out of buying a bottle that may contain pesticides and chemicals, it may even taste better.

With more of us choosing to buy organic - according to the Soil Association's Organic Market Report, sales of organic beers, wines and spirits saw an increase of 5.35% in 2015 - it could be that organic wines are not only earth-friendly, but we prefer the taste of the grapes.

"Recent news has told us again and again that organic wines taste better - perhaps due to the way they are made, with less intensive production using fewer synthetic chemicals," says Lee Holdstock, trade association manager, Soil Association.

"Some believe that the 'terroir', the unique environment and farming practices used to grow the grapes, affects the quality of the wine. It's a long-lasting belief that you can taste good earth in wine, and as organic farming keeps the soil at its core, it makes sense that organic wines should taste more of earthy goodness than others."

Here are some wines around the world you may like to try...

1. Cheers to Chile

With its near-perfect growing conditions and zero phylloxera (an insect pest), Chilean wine producers need minimal intervention in the vineyard to produce their sustainably farmed organic grapes.

At the forefront of organic wine production, the Miguel Torres winery hasn't used chemical insecticides or pesticides on their land for more than 25 years.

Try Miguel Torres Las Mulas Organic Sauvignon Blanc 2015 with just the right degree of tangy tartness, notes of citrus and tropical fruit and a crisp, refreshing finish.

2. Little Italy

One of the best Italian varieties from southern Italy, Fiano is one those bone dry, delicately fragrant whites you want to drink all year long.

A beautiful expression, try Zensa Fiano Organic 2015, which displays peaches and blossom on the nose, with mango and peach flavours and a touch of exotic fruit, with an oily texture that's balanced by zesty acidity.

3. French Flair

With Burgundy predicting a shortage of Chablis after suffering poor weather this year, choosing to buy organic Chablis is all the more meaningful.

Produced for M&S by Jean Marc Brocard and one of Chablis' leading producers, Organic Chablis Brocard 2014, Burgundy, offers a textbook stony minerality with pure, ripe citrus fruits, and an elegant creamy texture.

 A delightful expression from the chalky soils of this famous terroir.

4. So very good in South Africa

Could there be a better bargain than this smooth, easy drinking South African red.

Not the prettiest label to bring to the table, but Sainsbury's So Organic Cabernet Sauvignon punches above its weight with its vibrant, berry rich black fruits, blackcurrant aromas and full, flavoursome finish.

5. Postcard from Portugal

One of the largest farmers of organic wines in Portugal, Altano Organic Red 2014, Douro is an expertly balanced, concentrated red from the Symington family's stable of wines and ports.

A blend of touriga nacional and other native grapes, the wine is loaded with ripe, soft, blackberry and raspberry fruits with a light dusting of spice and a richly fruited finish.

6. California calling

A wine that you won't get tired of drinking, Bonterra Organic Merlot 2013, is marked by plums, cherries, toasty oak and vanilla spice.

Bonterra meaning 'good earth', it's soft, velvety and mellow, with lovely forest floor aromas and a juicy long finish.
