🍷 Found old bottles in a private wine cellar – stored horizontally for decades. Any chance they survived?

I recently discovered these bottles in a private wine cellar that appears to have been untouched for many years, possibly decades.

Known details:

• Private cellar, not commercial storage

• Bottles stored lying flat, directly on simple shelving

• Cool, dark environment, no light exposure

• Heavy dust buildup, some labels missing or illegible

• Exact origin and vintages unknown

I know that age alone means nothing and that most old wine doesn’t make it – but the horizontal storage and stable cellar conditions made me curious enough to ask here before touching anything.

Questions for the r/wine community:

• Based on storage conditions alone, is it reasonable to assume any survivability?

• What would you check first: fill levels, capsule seepage, cork integrity?

• Would you open a “sacrifice bottle” or leave everything untouched?

Not expecting hidden gems – genuinely interested in learning how experienced wine people would approach this situation.

Thanks in advance 🍷
