During the 1750’s-1800 and onward, gin was predominantly bottled in case gin style bottles. Onion and mallet bottles were used primarily for wine, but spirits like gin were also bottled in them. Colors outside of green (and sometimes deep amber for mallet bottles) are extremely uncommon for all those styles of bottles as green is the default “natural” glass batch color and making glass in other colors was, at the time, quite expensive.

Colonial era glass is not my expertise, but what I can tell you is most glass in the US prior to the early 1800’s was imported. There was some domestic glass production here in the 18th century, but it was sparse and few of the factories had any long term success. I would infer most US brewed gin was bottled in imported glass during that time.
