A standard length and diameter single punch cork in a high quality grading at a reasonable price. Corks are typically graded on a scale of 1-10, 1 being the best score, based on the degree of porousness that the actual punch of cork exhibits. Cork trees that show a higher population of worms or fungi tend to yield cork crops which are more porous. The Grade 3 corks show less than average porousness and are on par with the quality of cork used in many commercial facilities. Grade 1 & 2 corks are almost completely solid and sell at very high prices.
These corks are harvested and punched in Portugal, like the majority of the rest of the corks available today.
Grade 3 natural wine corks are rated for 5-10 years
