Labels:text | black and white | screenshot | newspaper OCR: PAGE 10 Sections D & E - Instruments, Grain Mill Testing for Sugar, Alcohol, Temperature, and Acidity The potential alcohol level of beer or wine being made is measured by a Hydrometer. Before D-2 fermentation starts (at the time the yeast is pitched) the Hydrometer is floated in the beer wort or wine must. A reading is taken at the level the Hydrometer floats to; the surface of the liquid. This reading is the original, or starting, gravity. This number is read on the specific gravity scale of the hydrometer, and in recipes you will see it expressed as "O. G." or "S. G." - starting gravity. After fermentation is over, at bottling time, another reading is taken with the Hydrometer. This one is the final gravity, or terminal gravity. In recipes, it sometimes appears as "T. G." To find the alcohol content of the beer or wine, subtract the terminal gravity from the starting gravity and match that number with the alcohol scale on the hydrometer. A typical American beer might be S. G. 1.032 - T. G. 1.008 = . 024. Twenty-four points on the specific gravity scale equals 3.2% on the alcohol scale. A heavy English ale would be about S. G. 1.054 - T. G. 1.016, or 5.3% alcohol. Hydrometer D-2 TRIPLE SCALE HYDROMETER Glass. Has balling, specific gravity, and potential alcohol scales. This instrument is accurate and dependable. Float it in the beer or wine before and after fermentation to determine alcohol content. This can be floated directly in the fermenter or in a #D-5 Hydrometer Test Jar. .. 4.95 D-S HYDROMETER TEST JAR Plastic, used to hold a test sample for hydrometers. 1.75 D-7 BREWER'S SLIDE RULE This product is a handy reference calculator that helps you figure ingredients and D-7 Brewer's Slide Rule amounts for different styles of beer. It includes a lot of information and has useful conversion scales. 4.95 D.9 ALCOHOLMETER Also called a Proof & Tralis Hydrometer, these test for alcohol (proof) in whiskey and hard liquor. Not for wine or beer. 8.95 D-14 FERMOMETER" New Product. This is a liquid crystal thermometer for monitoring wort temperatures during pitching and fermentation. Place it on the outside of the fermenter with the self adhesive backing. The Fermometer has a temperature range of 36 to 78 degrees Fahrenheit with two degree increments. Green indicates the stated temperature, blue one degree above, and tan one degree below. 3.50 D-15 FLOATING THERMOMETER This is a glass dairy thermometer that floats. It is easy to read and goes to 212 degrees F. This is needed to monitor brewpot and mashing temperatures. 5.95 D-17 HOP AND GRAIN SCALE 18 oz. capacity in 1/4 og_ increments. This scale Corona includes an oversize detachable bowl. . .. 12.95 Grain Mill D-20 ACID TEST PAPER for beer. 100 strips of Litmus paper centered in the 5.5 range for mashing grain beer. Dip the strip of paper in the mash water, then determine acidity by matching colors. . . . . 2.95 D-20a ACID TEST PAPER for wine. The same as above, but in the acidity range for winemaking. .. 2.95 E-5 CORONA GRAIN MILL This mill is made from cast iron to crush grains for brewing. We offer free crushing, but if you are going to store grain, it is better to store it whole and crush for each brew. . . 49.95 E-6 PHILMILL Made by Listermann Mfg. Co ., this fine roller mill is machined from tempered steel. This Mill provides precision crushing. Hand-cranked, but easily motorized. 79.95
