I see your point, Lisa. That does present a problem. There are some social funds that do not restrict alcohol.
Plus, I did some research and found out that there are a very few funds devoted strictly to wine and/or vineyards. Sadly, from a financial perspective, they have not produced the best financial gains. I honestly had never thought about wine as an investment before. The few funds I looked at all had very high initial investments (like 25,000 Canadian dollars) or were private equity investments that get very complex.
But this is a very good example of how an investment portfolio can be structured to take into each individual's values and tastes. Although alcohol is excluded from many social funds, wineries and particularly vineyards, do offer their own environmental benefits.
Perhaps a better alternative for supporting wineries would be to engage in peer-to-peer lending through one of the online p2p sites. Or, perhaps a local winery in your area is looking for an investor.
And there are alcohol companies that can be invested in such as Diageo which does produce wine. You could always buy stock in this company.
