For a long time, man has brewed beer without the aid of the most basic equipment. Thus we had to wait until 1760 before our breweries were equipped with the first thermometer. The densimeter made its appearance in 1705. And it wasn't until 1784 that the English brewery, Whitbread, used the first steam-driven machine. On a different note, microbiological discoveries brought about progress in our knowledge of beer. 

Louis Pasteur himself discovered that yeast is a microorganism that can be affected by bacteria. Nowadays, scientific experts are continuing to study the relationship between the taste and the aroma, along with beer's stability. The elegant copper brewing vats have been replaced by stainless steel models, which give better results. The various production phases have undergone remarkable technological progress.
