A creamery is a place where milk is turned into cream, butter, and cheese, or where those things are sold. It is a dairy word, a little old-fashioned and a little countryside: you meet it on farm signs, on butter packets, in food history, and on some modern ice-cream or cheese shops that want a handmade feel. Neutral, not slang; more written and commercial than café chat in Taiwan. Though actually, many new shops call themselves a creamery when they mainly sell ice cream, not when they churn butter — they are borrowing the old farm picture. It is not a bakery, and it is not the word for cream itself. English reshaped French crémerie to look like cream plus -ery, the usual “place of” ending.
