Featured Soda--Extremely Rare, pontiled Mystery SQUAT

Though not a soda, this DYER has the form and qualities of a beefy porter, with yes, a master ink style modified Saratoga top with pour spout. I have only seen one other, the smaller one--years ago. This larger one, though lighter in color, could be unique. But is it a food? flavoring? medicine? I listed it as a "soda" in the spirit of the rare, pontiled Dr. Thornton, Lewisburg, PA "syrup of wild cherry" squat blob. But research has uncovered that Dyer invented the extract in 1860 for Civil War Soldiers to make "instant" coffee in the field. Who knows? Maybe that's why the yanks won? It may have been a short production run in 1860 only, as both examples I've seen are pontiled, and by 1860 most of the glasshouses were converted to the snap case. Of course the caffeine content would have been high. A big gulp of the undiluted, syrupy extract might do well for a hangover--so I guess it could be categorized as "whatever used for". In any case - BEEFY !
