BAC, in distillery, vessels into which the liquor to be fermented is pumped from the cooler, in order to be worked with yeast.
Bac-Maker, is one who makes liquor-baes, under baes, coolers, mash-tuns, working-tuns, &c. for the brewers. The workmanship is partly carpentry, in a particular manner, for it must be tight enough to hold liquor; and partly cooperage, viz. the mash-tun, or vat, which is hooped. There are not many of this trade; and it requires chiefly strength, with a little art. A small stock of stuff, besides tools, will set a man up tolerably well; but, with 2000. or 3000. he will make a good figure in business.
