Warm and cup the glass with your hands. This will aid in releasing the aromas.
Bring the glass to your nose and inhale the aroma (fragrance) two or three times.
Take a small sip of oil, allow it to slide onto your tongue, now with your mouth slightly open suck in some air.
I was taught how to taste olive oil by the ‘Filippo Berio ‘Master Taster’ Daniele who is based in Lucca Italy. This gave me a great foundation, along with an in-depth knowledge and understanding and I think more than anything a real love for good quality olive oil.
