Conditioning in bottle

The test bench, entirely automated as described in Figure 9.14, allows us to simultaneously test 4 sensors using electronic cards. These sensors are tested in the same conditions thanks to Labview software controlling the automatic opening and the closing of the electro-valves. The gas nsed is conditioned in bottles and then mixed with air. At the exit of the bottles, a series of automated mass flow meters allow us to regulate the gas flow, fixed at 41/hr for each unit. 

In the past many beers were racked from wooden casks into bottles and the various maturation and clarification processes continued within the bottles. With a few notable exceptions beers are not now produced in this way. Beers conditioned in bottle have a sediment and tend to have distinctive flavours and aromas.
