Research carried out at the University of East Anglia has suggested that when it comes to fine wine portfolios, it’s diversity that truly is the key.

French wines such as Burgundy and Bordeaux vintages are generally considered the must-buys among wine aficionados but those behind the study have suggested that in terms of value, it’s best to have a well-rounded selection.

Instead of simply choosing to buy wines from across the Channel, the study suggested that wines from countries such as Italy, Australia and even Portugal could surprise a few.

The researchers arrived at this conclusion after investigating price fluctuations and finding that any falls seen in value tended to be clustered geographically, the Telegraph reports.

This signals very clearly that if just one French wine begins to lose value, then chances are that most others will do the same.

While this isn’t always the case, and fine wine is largely considered to be among the most robust in the world, it certainly does point to the fact that putting all your eggs in one basket, financially speaking, isn’t the way to go.

This was echoed by Professor Raphael Markellos, one of the authors of the study, when he summed up his findings.

Professor Markellos is quoted by the newspaper as saying: "From a purely financial perspective it makes sense to not put all your eggs in one basket – invest in French wine but also wine from other countries."

Factors such as bad weather were highlighted as a strong reason why wines lost value but there were also others such as availability of stock and the wider economy climate that played their part as well.

Italian, Australian and Portuguese wines named as the least likely to follow the same volatile trends as French wines.

The findings of the study may not be particularly groundbreaking but what they do say clearly is that French wine remains highly sought after, just don’t rely solely on them.

Instead, opt for a diverse, well-rounded group consisting of wines from all over the world.
