Рисовая водка. Часть 2. Ректификация. Буфер Шульмана.

In my previous video (Rice Vodka. Part 1), I talked about how I prepared the mash for rice vodka and how I distilled this mash into raw alcohol.    • Рисовая водка. Часть 1. Подготовка браги и...   This video is about the rectification of raw alcohol to obtain ethyl alcohol, which is used to make rice vodka. During the rectification, I used a device called "Buffer 2.0," "Buffer 2020," or "Shulman Buffer" (named after the inventor who proposed his modification of this device). You can also see more details about this buffer (I mention it at the 32nd minute) in the following videos:    • Новый буфер и паровой отбор - что может бы...      • Буфер 2020|Игорь Шульман|винокурение|самог...   The results of the GC analysis of the resulting rectified spirit and the tasting of the rice vodka will be discussed in the final part of the series. Throughout the video, I mention some stories from my channel "We Will Overcome": About Gabriel's method (7th min.)    • Ржаной дистиллят. Метод Габриэля   About the short-body method (ringing the heads and tails) (8th min.)    • Метод короткого тела (МКТ). Кольцевание го...   About the theoretical foundations of rectification on a packed column (16th min.)    • Популярная физическая химия для винокуров....   About the errors of electronic thermometers (46th min.)    • Какой у Вас градус?   Timecodes: 0:00:14 Introduction: my attitude toward vodka in general and rice vodka in particular. 0:05:44 Distillers and rectifiers.
