What is the relevance of only buying wines ‘Under Bond’?
Giles Cadman is a great asset in answering this question when it comes to investing in fine wine. See what he says: http://gilescadman.com/wine-blog/
Taxes are only paid on wine when it is released into free circulation so it makes no sense to buy wine outside the bonded warehouse system. Additionally a wine stored in bond can be checked with regard to provenance and its storage conditions are virtually guaranteed unlike a case of wine in free circulation which may have spent 5 years in the wildly fluctuating temperatures of an uninsulated garage.
