에스프레소=다크로스팅 원두?

“원두를 사러갔더니 어떻게 커피를 내려마시는지 물어보더라고요. 브루잉이라고 했더니 미디엄 로스팅을 추천해주던데 왜 그럴까요?”

선호하는 커피원산지 뿐만 아니라, 로스팅 정도 또한 개인별 선호가 다르기때문에 ‘브루잉=미디엄 로스팅’이라고 꼭 집어 말하기는 어렵지만, 많은 이들이 ‘에스프레소=다크로스팅’, ‘브루잉=미디엄로스팅’을 권하는 경우가 많습니다. 반드시 지켜야될 철칙이 아니지만, 에스프레소 커피에 다크로스팅 원두를 사용하게 된 이유에 대해 해외 미디어(scottrao)의 기사를 소개해드리겠습니다.

#1. 온도

커피는 저온에서 추출할수록 신 맛이 강해지는 경향이 있습니다.

신 맛을 좋아하는 고객도 있겠지만, 만일 신 맛을 싫어하는 고객이 노멀한 맛의 커피를 주문했다면 어떻게 해야할까요? 해결책은 간단합니다. 보다 고온에서 커피를 추출하거나, 강배전(다크로스팅)된 원두를 사용하면 됩니다.  그렇다면 브루잉과 에스프레소 중 어떤 쪽이 좀더 신 맛이 날 여지가 많은지에 대해 아래의 식을 살펴보겠습니다.

브루잉 에스프레소
무게 온도 무게 온도
커피가루 100g 25℃ 20g 25℃
1,600g 94℃ 70g 94℃
혼합물 1,700g 90℃  90g 79℃

독자들의 이해를 돕기위해 원문에서도 언급(I know this a gross oversimplification of slurry temperature. Please bear with me and focus on the forest, not the trees.)된 것처럼 지나치게 단순화했지만,  보다 많은 양의 뜨거운 물을 사용하는 브루잉에 비해 적은 물을 사용하는 에스프레소는 초반(“front loaded,” meaning a disproportionate amount (>50%) of coffee solids are removed in the first few seconds of an extraction) 추출단계에서 낮은 온도의 커피가루와 접촉하면서 온도 감소로 인한 신 맛의 커피가 나올 가능성이 높아진다는 점을 설명하고 있습니다.

물론 보일러 열용량 등 머신 성능이 개선되면서 이러한 상황이 발생할 가능성은 적어지고 있으니, ‘브루잉에 비해 에스프레소가 신 맛이 나올 가능성이 있다’는 정도로 이해하면 될 것 같습니다.


#2. 과소 추출

최근 다양한 커피 도구들이 나오고 있지만, 얼마전까지는 그라인더의 원두 분쇄도가 일정하지 않거나 너무 많은 원두로 추출하는 등의 이유로 과소추출이 생기는 경우가 종종 있었습니다. 이때 과소 추출로 생길 수 있는 신 맛을 줄이기 위해 다크 로스팅원두를 선택하는 경우가 많았습니다.

다만, 균일한 분쇄도의 그라인더, VST 바스켓, 커피굴절계 등의 다양한 커피 도구들이 나오면서 과소추출이 줄어들고 있기때문에, 단순히 과소추출로 인한 신맛을 피하기위해 다크로스팅을 사용한다는 생각은 잠시 접어둬도 될 것 같습니다.

#3. 우유 사용

카페에서 추출된 에스프레소는 바로 마시기보다는 라떼 등 우유베이스 음료에 활용되는 경우가 많은데, 이때 우유의 단백질/지방 성분이 커피의 플레이버를 낮추게 됩니다. 원문(scottrao)에서는 우유음료에 에스프레소를 넣을 때 커피의 플레이버가 가려지는 것을 막기위해 좀더 강한(다크) 로스팅이 적합할 수 있다는 의견을 제시하고 있습니다.

물론 음료의 종류(핫 or 아이스)와 원두의 특성에 따라 달라질 수 있으니, 손님이 오기 전 미리 음료를 만들어서 어떤 원두로 어떻게 추출할 지 조정하는 것이 중요합니다.
