Frequently Asked Questions

Our courses cover sensory analysis, brewing science, microbiology, and quality control for the food and beverage industry. We're adding new courses regularly.

For the full and current list of available courses, please see our Courses page. Each course page sets out what's covered, who it's for, and what's included.

Our courses are designed for professionals working in the food and beverage industry — particularly in brewing, beverage production, quality control, and sensory analysis.

Each course page sets out who it's suited to and any prior knowledge that's helpful. Most of our courses don't require specific entry qualifications.

All courses are delivered entirely online through our learning platform. You'll work through video lessons, written content, and interactive quizzes at your own pace.

Some courses include a physical training kit (containing reference compounds, flavour standards, or other materials) shipped separately to your address. The course page tells you what's included. The digital course content can be started immediately — you don't need to wait for the kit to arrive.

Yes. When you successfully complete a course (which usually means working through all the content and passing the assessments), you'll receive a digital completion certificate in your name. Certificates remain accessible in your account.

Our certificates are completion certificates. They evidence that you've successfully completed the course on Nexus. Any external accreditation for a specific course will be noted on the course page.

It depends on the course. Each course page on our Courses page gives an estimate of typical study time.

Your access period is designed to be generous — with plenty of time to work through the content at your own pace. The exact access period for each course is shown on the course page and again at checkout.

Browse our courses, add what you'd like to your cart, and check out. You'll need to create an account during checkout (if you don't have one already). Once payment is confirmed, your course access is activated immediately.

Yes. We work with businesses of all sizes, from independent breweries to multinational beverage companies. At checkout, you can enter your business details and VAT number. For larger orders, we also offer Group Seats and purchase order terms (see the Payment section below).

Yes — particularly useful for businesses needing internal approval or budget allocation. Email hello@nexusbycara.com with the courses and quantities you need, and we'll send you a formal quotation or proforma invoice.

Quotes and proforma invoices are valid for 30 days. After that period, please request a fresh quote.

Once payment is confirmed and your account is enrolled, your access begins immediately. You can request a refund within 14 days, with the amount depending on how much of the content you've accessed.

Our full position — including worked examples — is set out in our Refund & Cancellation Policy.

We accept all major credit and debit cards (Visa, Mastercard, American Express) via Stripe, and payments via PayPal. For business customers, we also offer purchase order terms (see below).

We display prices in British Pounds Sterling (GBP), US Dollars (USD), and Euros (EUR). The currency conversion is based on prevailing exchange rates at the time of purchase and may fluctuate from day to day.

If you pay in a currency other than GBP, your bank or card issuer may apply additional conversion charges — these are your responsibility.

Yes, for business customers. We accept purchase orders subject to certain conditions including a minimum order value, standard payment terms, and a valid PO number from an authorised representative. Longer terms can sometimes be agreed in writing on a case-by-case basis.

To discuss purchase order terms or check current minimum order values, email hello@nexusbycara.com. Full terms are set out in our Terms and Conditions.

Yes. We issue VAT invoices electronically for all purchases. Business customers can provide a VAT number at checkout, which will appear on the invoice. Our VAT number is GB 492 3199 23.

Yes. Payments are processed directly by Stripe or PayPal — both PCI DSS compliant providers used by millions of businesses worldwide. We don't see or store your card details; only a transaction confirmation and the last four digits of the card used.

Each course has its own access period, which is shown on the course page and confirmed at checkout. Individual courses and bundled programmes have different access periods reflecting their relative content.

Your access period starts on the date your account is enrolled, regardless of when you first log in.

Our access periods are designed to be generous, and we expect most learners to complete well within them. We don't routinely offer extensions for personal reasons or workload, but we will extend access for free if a technical issue caused by us prevented you accessing the course (for example, a platform outage).

If you've run out of time and want to continue, you're welcome to purchase the course again.

Your certificates remain accessible in your account even after course access expires. You can log in and download them at any time, as long as your account remains active.

No. Each account is for a single named individual. Sharing accounts is a breach of our Terms and Conditions and can result in account suspension without refund.

If you need access for multiple people, look at our Group Seats option below — it's specifically designed for organisations enrolling several team members.

Our certificates are completion certificates issued by Cara Technology Limited. They demonstrate that you've successfully completed the course content and assessments on the Nexus platform.

If a specific course has external accreditation, it will be noted on the course page.

No — some courses are digital only, and some include an accompanying physical training kit. The course page tells you what's included before you buy.

Physical kits typically contain reference compounds, flavour standards, or other materials used for sensory training and evaluation.

We dispatch kits via door-to-door international courier services. Transit times depend on your destination and customs clearance.

You don't need to wait for the kit to start the course. Digital course access begins immediately on payment, and you can typically complete the early lessons without the physical materials.

Our delivery charge covers shipment from the UK to your address. It does not cover customs duties, import VAT, or any other charges levied by your country's customs authority on arrival — these are your responsibility as the importer.

Import costs vary significantly by country. If you're unsure what to expect, your local customs authority or a customs broker can typically advise. You can also email hello@nexusbycara.com before ordering if you'd like to discuss.

Full details are in our Shipping & Customs Policy.

If the delivery fails because of something we or our courier did wrong, we'll fix it and re-dispatch at no extra cost to you.

If the delivery fails because of something at your end (such as an incorrect address or unavailability to accept delivery), we'll arrange a re-delivery attempt at your expense. After two unsuccessful attempts, we'll cancel the kit portion and refund the kit price (delivery charges are not refundable in these cases).

Yes, but only if the kit is returned unopened and undamaged within 14 days of delivery, at your own cost. Once opened or used, kits cannot be refunded for hygiene and safety reasons.

Most kit contents should be stored cool, dry, and away from direct sunlight. Detailed storage and handling instructions are supplied with each kit — please review them carefully on arrival.

You're responsible for complying with local laws on storage, handling, and disposal of the kit contents, and for ensuring the kit is used only for its intended purpose.

Yes. Our Group Seats option lets you buy multiple licences in one purchase and allocate them to named individuals within your organisation. Ideal for training a whole QC team or onboarding new sensory panellists.

To discuss group purchases, email hello@nexusbycara.com with the number of seats you need.

Once a seat has been enrolled against a named user, it can't be reassigned. This is to protect the integrity of completion certificates — certificates are issued in the name of the person who completed the training.

If you have unallocated seats (purchased but not yet enrolled to a person), you have a window to allocate them. The exact window is set out in our Terms and Conditions.

As a Group Administrator, you can see the following for each user enrolled against your Group Seats:

• Name and email address
• Courses they're enrolled in
• Enrolment date and access expiry date
• Their progress through each course (typically as a percentage)
• Quiz and assessment scores
• Whether they've received a completion certificate

You don't have access to their detailed lesson-by-lesson interactions or any personal information they've shared with us beyond the basics needed for training administration.

The seat that employee was enrolled against remains with them — it can't be transferred to a different person. Their progress and any certificates earned go with them as a personal record.

If you have unallocated seats remaining (within the allocation window set out in our Terms), you can enrol a different person into one of those.

For larger group purchases, we're happy to discuss volume pricing. Email hello@nexusbycara.com with the courses and number of seats you're considering.
