I've recently discovered that the beer Oude Geuze Boon can be stored up to 20 years and only improve in flavor. Seeing as this beer is rather special and might not exist any more in x years time due to the changing climate it might be a fun endeavor to buy some crates and see what they'll be worth in 5-15 years time.
Now, wine and whiskey are established beverages to invest in but I've yet to really see any old beers on the market besides some very strong, brown beers.
Are people actually willing to buy old beers? Would they prefer 33cl or 75cl? Is it feasible to store beer up to 10+ years?
Thanks in advance!
