What is meant by a noggin of cider?

A "noggin of cider" is a rather old-fashioned and quaint way of saying a small amount of cider.

Here's why:

* Noggin: This term, now mostly used figuratively, refers to a small wooden cup or mug, often used for drinking ale or cider in the past.

* Cider: A fermented apple juice beverage.

Therefore, a noggin of cider would be a single serving, likely a few ounces, poured into a small cup.

While the term "noggin" itself isn't very common today, it adds a touch of old-world charm to the image of enjoying a simple cider.
