In the case of hop powder, hop powder with higher lupulin content, extract of hops and mixed hop products, the attestation may only be recognised as being equivalent to the certificate if the alpha acid content of these products is not lower than that of the hops from which they have been prepared.
Humalapulbri, suurema lupuliinisisaldusega humalapulbri, humalaekstrakti ja segatud humalatoodete kohta võib tõendit sertifikaadi asemel tunnustada ainult siis, kui alfahappe sisaldus nendes toodetes ei ole väiksem kui humalas, millest need toodetud on.
