Which of the following technologies significantly impacted brewing?

The choice indicating that all of the listed technologies significantly impacted brewing is accurate because each technology has played a crucial role in the development of brewing practices throughout history.

Kilning is the process in which malted grain is dried using hot air, which helps to develop color and flavor in the malt. This is fundamental for providing the base ingredient for brewing beer, and advancements in kilning techniques have allowed for better control over the roasting levels, which in turn impacts the taste and quality of beer.

Glass bottles revolutionized beer packaging and distribution. Before the widespread use of glass bottles, beer was often stored in less protective vessels, which could lead to spoilage or contamination. The introduction of glass bottles allowed for a better preservation of flavor and carbonation, while also making it easier for consumers to purchase and enjoy beer outside of taverns or breweries.

The stewing method of kilning refers to an alternative technique utilized in the malting process, where grains are subjected to lower temperatures and controlled humidity to produce a more aromatic malt. This method can influence the flavor profile of the final brew significantly, making it an important advancement in brewing technology.

Since each of these innovations has contributed to the progression and improvement of brewing practices, recognizing their collective significance in the history of brewing makes
