Turnaround Times for Smoke Impact Testing

For Current Clients

We are currently reporting from grape berry smoke impact samples received 28 August, and from wine samples received 3 September. Grape berry samples received early today are projected to be reportable in mid November, and wine samples received early today are projected to be reportable by 7 November. Projected reporting dates for samples received later in the day will depend upon the number of samples received during the day. Estimated due dates for samples in the laboratory may be viewed in your client portal. For help with understanding estimated reporting dates, please click here.


For Those Not Yet Clients

If you are a new client, we will be pleased to set you up and to accept your samples. Samples other than smoke impact analysis samples will be accepted and processed immediately with pleasure. Smoke impact samples will also be accepted, and we anticipate that we will be able to start processing these samples not sooner than the end of November. We understand that this may not meet your needs. Here is a list of other laboratories who are offering smoke impact analyses.
